Wish it just connected to the OBD-II port.
The best thing about the engine cover is that it doubles as a boomerang. I’ve seen several videos with Paul throwing the cover in a bin, but it’s always back on the car in the next video.
I did a update on my GTi MK8. At the dealership they told me that they have to remove the engine cover. I asked why and the answer was it could break off and light the car on fire 😅😅😅😅
lol ask to see it now
Paul out here helping the community 👏
I had a JB4 on my N55 335i, using both 93 and also a 60/40 E85 mix using the Flex Fuel addon. It made a massive difference, wheelspin in 3rd gear on a bone dry surface and pulled like a champ. Ran it for 3 years and never had a single issue. Never went crazy with the tuning so it was perfect for me.
The piggyback explanation had me rolling 🤣😂!
I went by your guys shop to try and see if the shop would be interested in doing service on my mk7 gti and they really weren't interested do to me being an APR stage 3+ with a custom mapped JB4 on top. But the workers were very nice and respectful over all! Even with 2 years of owning the car still learning on the jb4 side of things and the car in general.
Ran the JB4 for nearly 3 years and zero DT1 or warranty issues. Didn’t even really hide mine well at all and no tech even asked me about it. So at least in my Mk7 GLI no problems. However now that I’m out of warranty and running a flash tune I have to admit they are way better.
Usually you need more octane to make better power on the higher maps... Blending in some E85 does wonders on JB4. Piggybacks cannot modify ignition timing. You run into a situation where ignition timing is over advanced for the actual boost level. You need more octane to combat timing pull.
Just purchased my JB4 from shopdap because of this video and the $50 I saved compared to my other favorite store (BMP). Thank you for the install video for when it arrives! Have you considered doing a video on intercoolers? I’m interested in MK7 models.
I opted for the Bluespark Pickyback.
Works great adding 40 extra hp. 👍
i hid my jb4 box behind the battery. wiring is pretty tight that way but it reaches all the way to the lower boost pipe just enough to not stress the connectors.
Great explenation!!
I recently saw a jcw countryman mini cooper with a piggy back on it and it was throwing a check engine light for the waste gate. I honestly couldn't feel enough of a difference between it and a stock one to recommend it to anyone over an actual tune.
I'm running a JB4 on my S3, very happy with it. I ran one on a F30 328 as well with good results. A few notes, the USB cable can also interface with the app on your phone by using an OTG cable with compatible phones. Also, there really is no great place to mount the JB4 on these platforms, I squeezed mine between the battery and airbox.
Did you get a check engine light and other lights after your install? I got a few just now after completing my install
Those soft engine covers are wild, they look like solid plastic so it really surprises you when you touch and feel it's foam
Just wait till they start disintegrating in like 5 yrs
They are gonna make a real mess when they fall apart
@@j.m.5995 There has actually been a recall on these engine covers.
Took mine off lol
I had a friend with a mk7.5 with a jb4 and a catback. That thing was neck and neck with mustang GT’s and Camaro SS/LT1
Great review.. Normally a splash of E85 such as 4-5 gallons is recommended for map 5 for that much boost and fueling. The HP and torque numbers would be dramatically higher. Would love to see another vid with a custom map with higher octane and/or E blend. Also 1/4 mile run with the JB4 for comparison. Great explanation and install👍
I hate that not many people know about the Octane benefits that E85 brings to the table for turbocharged engines.
Weird in UK our petrol went from E5 to E 10. Or 10% ethenol and my car puts out less power, worse mpg on it. Golf Gti mark 6.
But doesn't piggyback cause the engine to only allow boost with high octane or running methanol injection? So therefore it ramps up fuel pump and therefore it can become where your 5 gallon tank of methanol is depleted in 30mins in your small engine turbo vehicle but you only hit half throttle in those 30mins?
@@knightrider1545 The 5 gallons mixes with the 91 or 93 and raises the overall octane level. The ethanol burns cooler as it's alcohol based. You don't burn through that 5 gallons separately, this has been used for years in tuning. There are many E85 calculators available online for reference. JB4 has logging capability so it can be analyzed how the E-blend is affecting fuel trims and AFR'S. Then you can make a custom map accordingly or just add power to the OTS maps as they will auto-tune for it.
@@lotusluke86 You can run up to an E30 blend with a JB4 with no flash.
JB4 Stacking is basically essential on the MK6 Gen 3 non MQB while taking advantage of the custom turbo swaps for ISXX turbos! Since most custom tunes aren't available for everyone! Just a friendly info plug :)
Being familiar in Jersey accents after working in the state for 5+ years, I can confirm Paul's Jersey accent is official.
Holy fucking shit a My New Haircut reference in a GTI video? AMAZING
Nicely done. Ihave a mk7 R but notice there was no posit tap to connect on your mk8. Has there been a revise change to mk8 install?
The bluetooth connect module is only required if you have an iPhone. If you have an Android device, the wired USB cable from the JB4 will work with a USB OTG adapter connected to your Android smartphone. I ran my setup like this for a while on my previous MK7 Golf R.
Isn't the cost of the adapter and the jb4 data cable close to the cost of the bt adapter?
@@catinthehat5140 Not even close. The JB4 data cable is currently $40 (I bought it when it was $30), and any USB OTG adapter on Amazon costs $10 or less. Compared to $140 for the BT connect kit, that $100 delta was hard to ignore. Personally, I didn't find the wired solution to be that inconvenient.
What are your wheel fitment dimensions? Any rubbing? Looks good!
OMFG!!! I love that T-Shirt!!!
I had a JB1 on our MK7 Golf R for years and was always happy with it, especially given the cost. I recently moved from the JB1 to a 93 octane 034Motorsport tune and while it's a night and day difference, the full ECU/TCU tune was significantly more expensive.
The JB4 on the other hand, the prices are much closer to the costs of full ECU tunes. But, at least in the case of my B9.5 SQ5, the power increases aren't that far off from full ECU tunes.
I had the exact same thing as you and when I upgraded to a Stage 1+ and also had the TCU tuned and it was a noticeable difference. And the car drove better thru the whole power band and shifted better. Once being on a tune I would never go back to a JB. But they are a good option for folks for sure!
Good job
Can you perform a 30 or 40 mph pull between mk7.5 and mk8?
Another great video !
So would you recommend a piggy back is one is concerned about warranty? I was thinking one could remove the piggy back when you take the car the the dealership for maintenance, but clearly looking at the install, no. Or is there an easier way to do this?
Can a IE intake and turbo inlet cause the same kind of air volume issues and suck up the boost on a stock tune? Planned a stage 1 tune but probably gonna wait till the fall now but I already put in the intake mods and car feels like it lost a little pep at times. Especially when it hot a humid. -Mk7 GLI
Also I'm local to Reflect tuning!
Badass !
I missed the video you mention, that should show how can I plug the piggyback to the turbo sensor in the lower part of the engine comprtament.
Where can I find it?
Thanks!
Hey, not about this vid but you do you have a video on how to do a transmission guild oil change on 2013 Audi a4 2.0tsfi??
Last time I installed a piggyback the ColorShare where not correct either. And the reason was the item was build in England and they have all cables on the opposite spots
what octane fuel are u running? I have mk8 and a jb4 being shipped to me but I only have access to 91 hopefully I can still make some good power also doing cold air intake and cat back full exhaust.
Jb4 is good for its safety features, it's good for its boost control logging and monitoring... not keen to it making power when I ran it I used a backend flash. How I would continue to run it
Stacking is good for more than just WMI or trying to override a tune for the same fuel with even more boost. You can use it to buy a lower octane tune if say you only have 91 available normally, but can find 93 or e85 sometimes too, dial in some Map 6 settings for each and save them as profiles to use to make your tune far more flexible.. It also doesn't override ECU safeties, it takes a LOT to blow your engine that way! LOL... Love ya Paul, you are a great asset to the community!
Maybe it's different on this car, but on my mk7 Golf R you had to do 3 to 4 pulls in higher gears before you would get all the power from the JB4.
Did you do that on the dyno?
Is that because something the jb4 is doing?
@@catinthehat5140 yes. It needs a couple of pulls before it knows what's what😁
@@ProjectSimRacing why?
@@catinthehat5140 I guess it's because it needs some readings of the car first
Nice
Good job , I think race chip is much easier
For some reason I also remember having to tap into AFR wire when I installed this on my R.
varies by car
Yeah I had to as well on mk7 r.
was just going to say the same thing. Had to tap into the wire and get that lambda for my mk7 install
I had cam, boost,map,afr and fuel rail for mk7 gli
I'd recommend buying the cable and then picking up a USB-A to USB-C adapter to plug into your phone. I do it and you get app access without paying $150 for the Bluetooth
Can u use E30 mix with stock fueling in the JB4? I have a 2021 GLI S
Wait so you have to pull wires through from the engine bay to the inside of the car? Man I think I’m gonna order Racechip instead I can’t be doing that everytime after a service from the dealership
Which version of the app is this? I have a JB4 for my mk7 and I don't have the PSI numbers and octane on the Map selection page. I'm on the current version of the JB4 app. The PSI numbers for Maps 1 through 3 are 1psi lower compared to the Mk7.
"Map 1: Tuned map with a average of 4.0psi over stock. This is the shipped map and is compatible for both 91 and 93 and can be used with cars on hardware.
Map 2: Tuned map with 5.0psi peak boost over stock. 93AKI/98Ron recommended
Map 3 Peak boost 6psi 93AKI/98Ron recommended"
Can you use these on custom turbo builds that were originally N/A? Or is it only for factory turbo cars...
I ran 95 octane for 10 000km in my GTI MK8. It has a piggyback installed. Should a run 98. Is it safe to switch now ?
HGP Turbo in Germany has mk8 ECU „cracked“ they are the only one world wide at the moment, afaik….
@William Arrington wow, i think you dont know HGP Turbo.....how about google the company first and look for some videos here on TH-cam? you make yourself look kinda stupid, sry.....
Great camera work on this one.
Also, is the clutch slipping yet?
Nope. Not sure it will since the power bump isn’t huge
JB4 for mk8r's different than mk7r's? My S3 8V unit has AFR tap as well
So I finally was able to test drive a GTI S manual. I liked a ton about it other than two things. The tech interface and just adjusting the hvac, radio, etc was a pain. You need a tutorial before you try to do this and drive. The other is it felt like the computer was reducing boost in 1st and 2nd gears. It didn’t feel like a gear ratio thing to me as when I shifted to 3rd or 4th at whatever rpm, the boost hit almost immediately. I prefer the mk7’s dash design, but things change and I don’t buy used cars anymore. Is there a handheld tuner coming? That might dramatically help 1st and 2nd gears.
Boost reduction to help prevent wheel spin totally makes sense, the JB4 also offers this in its settings as well... but yeah, if you don't like it most likely will have to wait for a real ECU flash tune that eliminates this.... Also, the S at least has a volume and tuner knob, that does help quite a bit but indeed there is a learning curve and becoming accustomed to the controls, I can see that being frustrating at first!
Too much power causes wheel hop in 1st even with the LSD on the gti. Seems though if you get a certain sticky tire this can be reduced
Did you connect the AFR wire? My understanding is this is how it monitors and manages the fuel bias. Without tapping the AFR, you aren’t allowing the piggyback access to any of the information that separates the JB1 from the JB4 and it defaults to the lower boost levels for the other maps since it is missing information. This may also explain why there wasn't more power difference between the maps. Just a thought....
Not needed on the mk8, that varies by car
@Stephen Romano Oh, OK, didnt know that. I just know on the MK7.5 it makes a big difference without the afr wire connected.
When you don't install the AFR wire on MK7 it does NOT default to lower boost levels at all, it just can't add fuel to keep up with extra boost and you will run lean if you push it too hard. For instance, I tried Maps 1-3 without the AFR wire on my MK7 1.8 and once on Map 3 I could see my AFR's creeping up a little, I had perfect AFR's under Maps 1-2. Then, once I got the right connector and hooked up the AFR wire, my fuel trims went up as it added fuel and my AFR's went more rich and I went on to dial in Map 6 from there.
with all the mod's you do in performance, what mod's would you suggest to increase fuel mileage considering price of fuel going up???? sure that would make for nice vid.
not much will help with mileage.. 90% gonna be from the way you drive the car. MAYBE you could ask a tuner to tune the car for gas mileage but no "mods" you bolt on will help lol
Did you log the dynoruns? You where likely pulling timing so log trims and AFR with 2 gallons E85 to see if it can handle it and put it back on the dyno.
probably true. We did not log
Question, do you have any idea what DSG and ECU firmware updates do in practical terms to Audi cars?
Do they help drivability (smoother gas or gear change)?
The tcu I upgraded to stage 1 and it made the transmission perform and behave much better even in normal driving mode. I think its a very good upgrade. The ecu tune I did to a stage 1+ which really made the car fast, not just quick. And yet it drove just like a normal car otherwise. I've been running it for 3 years and its a great change I would never want to go back to stock.
@@vroomgc I am sorry I didnt make it clear when I said firmware upgrade. I mean the updates supplied by Audi and VW that are sometimes installed to fix some issue or just during regular maintenance :)
I know how much a Stage tune benefits the car. I was just interested in those OEM firmware updates:)
@@F.S92 Oh ok Ive never had one of those for the 5 years Ive owned the car
Good video as always. I feel like you slightly poo pooed the jb4 in the past. Tunes are probably better but the jb4 has it's place and some advantages if you're running like a stage 1 just bolt on type of car newer car. Either way seems like both companies have a huge VW following.
Never intended to poo poo. Just previous discussions were in comparison to tunes.
One issue is that the jb4 ÷ Bluetooth + app is close to $700.
I'm about to install this tomorrow on a 21 Acura TLX TYPE-S it will also get a high flow catted downpipe with 200 cell & a cat back non resonated exhaust with valvetronic, so I'm looking for a pretty good sound plus that Jb4 experience, hopefully is much easier to unplug than it is to install it at least on this car it doesn't look that easy to uninstall quickly
What’s the verdict? Was it worth it? Please don’t just say yes cause you spent money on it lol, would you have rather gotten a tune?
@@A_Guy123 Yes! definitely worth it but it depends on what you're looking for, for me I like a deep sounding exhaust which is exactly what I got plus it gave me a little more HP, now just waiting for K-tuner too come out with more units & maps to me Jb4 isn't the same but it's ok.
@@djsthemetereman lol I was talking Jb4 specifically as I know I’ll get a down pipe on my MK8 GTI whenever I get a flash tune. However with being tired of waiting and wanting to keep my warranty I was wondering if the JB4 was viable over a tune if it actually did anything noticeable as most people say “it needs time to see real gains”
@@A_Guy123 I gotta say I didn't feel that much of a difference personally & wish I just would've waited for K-tuner, now with that you can really feel a difference also there's no worry about warranty, I flashed my 18 Acura TLX aspec multiple times & the dealer never mentioned it because I'd flash it back to stock so apparently they weren't even looking for it & that's even after the crankshaft went on it causing me to have to get a new engine
Paul did your clutch slip on the jb4 tune? Did you ever end up replacing it or still running stock? It's comical this thing can produce so much power with just a jb4 that you have to worry about your clutch. I want it!
Stock clutch still no slipping
How did you get your map settings to show the octane and psi? My app doesn’t have that so I have no clue what map is made for what. Are they the same for my mk7 GLI jb4?
I'm also interested in this, mine just says map 1, map 2 etc
Month ago i bought RaceChip for my VW Polo 1.4tsi. Also a good product from germans.
I understand why OEMs like VW lock down the ECU so well (warranty,emissions,EPA,CARB 😔), but can’t they just open up the ECU for the end user and allow aftermarket users to get a remap/tune?
We’re constantly in this dance where tuners are cracking the ECU locks and validations and then months, sometimes years go by and then finally tunes are available.
This is a decent stop gap in tandem of stock calibration; it’s a cool way to get quick power and safely with warranty. Yes there’s ways to detect this but the effort to go through would be almost moot. Just take it off before going to the dealer and you’re safe.
Great Video! Wish I got to make a way out to Lindsay VW when you picked it up!
We will be at Wookies, and Alpine both east coast events

Apr is sending me a piggyback until a tune is available and no cost too me!!!...all I have to do is give them feedback.
Hi used to be red chipz on here now watching all your vids again, as email was hacked, nota problem, do you know as your always tossing your top engine cover in the trash, that you can order revised one from vw, just got mine only £135 uk price tc love watching them all again only took2days from ordering
the jb4 fits inside the cloth battery cover just down the side of it
We want tuned Golf Gte and compare it to
Gti.. power torque and mpg. These fuel prices.. 🥶
All I want is stock tune without speed limit (My 1600 kilometers MK8 GTI can't go faster than 206km/h).
Hell yeah the "My New Haircut" video made a comeback!!! F'N SKANKS!!! "My New Honda" is a great parody of that one. Well worth a watch if you haven't seen it.😂🤣😂🤣
The kicks look great on your car btw Paul! Worlds better than the OEM ones IMO 👍👍😎
Nice review. When I switch maps on my MK7.5 R JB4 it does not have the map notes in the IOS app like in this video. Can those be turned on, or how did they get there?
I think BMS gave him a Beta version of the app to use or something...
302 HP at the wheels stock??
Pretty impressive, and hugely under rated, if that's true.
Ah! Thanks!
That was the torque, they got around 250ps which is 246hp
I’m a owner of the mk8 GTI clubsport not the 245 GTI
Iv been meaning to ask this but a little bit afraid of been called a idiot
The CS mk8’s engine, turbo EVERYTHING is exactly the same as the golf mk8 R
it bhp figure runs with what the R is doing on tests
320 (340/350 really the R)
300 (320/325 in the CS)
I know this because it’s been dyno’d now 3 times
My question is this
Would the mk8 R software for its bhp output work on the CS? like Iv said everything inc the ecu (serial numbers etc) are the same on both models except the 245 GTI
I’m just curious thats all
Surprised that they are still using DB9 ports
ok i’m confused will cobb be doing flash tunes?
I have a issue with my Mk7 with 100,000 miles.
A misfire on cylinder 3 only, misfire is only on idle.
Did compression test 190 on 1,2,4 and 160 on 3. Changed spark plugs, coils, injectors, and did a carb clean.
Any help on what it could be the issue would be appreciate it.
What happened when you plugged in the jb4 and boosted it up?
Based on historic VW trends, get a new clutch ready. The tissue paper they call a clutch disc is already inadequate at stock power levels. The dyno results show that the turbo is already at its max with the 1st tune used. Past that point all you may see is a low RPM boost spike. After that just blowing jot air and losing turbo efficiency.
I was watching another company here on youtube. They installed an exhaust, intercooler, intake and the JB4. Power numbers were higher. But after a few runs on the dyno he said he smells the clutch.
It’s a weak pressure plate, not the actual clutch disc that’s the issue.
Surprisingly my EQT stage 1 MK7 is holding strong on the stock clutch for now, then again, I don’t floor it in 5th
Is this only on 91+? Could I use these maps if I’m running on 87?
Is the JB4 as good as the RACECHIP unit?
Paul I need one of those chain gang shirts please
make something for the Elantra N :)
Does the car log data for a set amount of time/distance? If so, couldn't the shop detect you have over boosted in the last 50 miles?
The ECU doesn’t know it‘s „overboosting“ that’s what the JB4 does. The ECU thinks it’s all normal.
@S B i know the ECU doesn't produce an error code. However, the pressure will still increase. I can see this on live data on my Audi. So, I was wondering if this information is cashed somewhere. Also, the probability of a shop finding this data is slim to none.
@@macrolosses the ECU doesn't see the pressure increase, that's exactly how this system works.
Makes the ECU think it isn't making enough boost.
@@mwmm exactly
So I was under the impression that the jb1/jb4 takes a while to fully trick the system. Maybe if you left it on the 5psi map and came back to the dyno a different day with similar weather would have different results?
Possible. We will test more in the future and let Charles’s know to dyno on the tuned version first
Have you found that the Jb4 hasn’t made a such a big improvement on the MK8 GTI than with the IS20 turbo in the mk7 GTI? I have the Mk4 VRS (2021) same as MK8 GTI and in Australia they didn’t come with the Garrett turbo, they came with the IS20 (but same ECU that hasn’t been cracked yet as the euro Mk8 GTI). Kinda wondering whether it was a blessing in disguise to get the IS20…
you don't have the new gen 4 ea888 in the VRS, you still have the gen 3 ea888 that's why you have an IS20.
@@tf6437 You sure? There are differences from the mk7.5 GTI / Mk3.5 VRS ie it doesn’t have port injection anymore. Might be a blessing in disguise the is20 is bigger than the Garrett by a small margin. Exhausts will sound better with no OPF. We do have the newer ECU though which is annoying as it can’t be tuned yet
@@Dave-gg6vl yes I'm sure, MK8 in certain markets didn't get the Gen 4 yet either
@@tf6437 do you know why this is? What is the justification?
im getting a mk8 gti at the end of next month and im wondering about the reliability of the JB4, is it safe for the motor and the ecm in the long term?
On my audi i turned down map 1. Gives more power with as little as 1-2 psi extra boost. Mine runs at 3psi all day instead of the default on 93 octane.
yes as long as you run the correct map for your fuel octane
Today's ECU's are so powerful they can pull timing near instantly when needed, but VW/Audi leaves *so* much on the table for power that with a JB4 that keeps you from running lean it's no big deal at all.
Probably a stupid question, but will the jb4 be okay with everything else stock? Or would I need to add some modifications ?
Normally fine, stock intakes aren't a constraints for small hp increases
Jagerbombs....you started with Jagerbombs.... LMAO!
safety recall 10h5 / engine design cover.. good thing you tossed it in the trash
Hey, do you know if the jb4 says all of those readings for the mk7.5. When I click on maps all I see are the individual maps and not like the +4.5 psi or whatever
I hear it's an app version thing, maybe only for iPhone I believe or they gave him some Beta version of the app to try.
Is there a piggy back upgrade for a 150 hp Gen 3 TDI engine
Sounds great but it's all going to have to come off if you want to sell or lease return through VW as the first thing they'll ask is "has it been modified"? If the answer is "no", you're likely to get a nice fat cheque since new cars are in such short supply.
Doesn't take *too* long to remove at all, these have been around for a while on a number of models, what sucks is if you do want to make a warranty claim it has to come out too, including the PIA OBD wire through the firewall.
Why is there no ecu tunes for the mk8 ?
Did i miss a video? It has an intercooler and wheels now.
Intercooler was testing fitment which is why we didn’t make a video. We will have one in the future.
Hey Paul, the trim around the sunroof on my mk7 gti is cracked on both sides. How difficult is it to replace?
Not sure what trim you’re referring to but email us with a picture and we can help you find the part.
I've done it 3 times. It's like 4-5 houers of work and I wouldn't say that's easy. And I think it costs around 700€ only for the trim.
Has anyone installed one on a manual mk8? I bought the JB4 not knowing that you have to connect to the OBD. All videos so far only show the dsg installation. There really doesn’t seem an easy way to go through the firewall to get to the engine bay. I’m almost thinking of selling it and look for another option.
Power numbers from JB4 alone?
Does the EA888 gen 4, US version, have dual injection...or still only direct?
No Gen 4 engine have dual injection. They are all direct injection.
Can something like this piggy back help with “rev hang” as found in the MK7 Jetta 1.4t ?
Nope, it really just adds boost and some fuel as needed, doesn't change any characteristics of the tune other than if you want to add *more* boost by gear reduction if you have too much wheel spin/hop.
Can the stock clutch handle it? A lot of people say their clutch slips after tuning their car.
Just replying to follow the answers
With this much power yes I don’t think it’s a major concern.
Hi have you experienced any "Error: Drive System. Please visit workshop" if so what do you do to get it back to normal
Still waiting on a reply... im pretty sure it does but you guys are not mentioning it... The sensors is very sensitive and can pick up changes in boost.
Is it true that there's no power difference between 87 and premium? I haven't seen any dynos or track times proving or disproving it
Good question, I want to know as well and I wish he mentioned fuel quality... but with a JB4 you def need premium to get gains, the added octane will keep it from knocking with the added boost, so for now it one of the few ways to add power with premium on these.
Stacking is what blew my mk7 gti motor, def not doing that again.
Is it just me or does the bonnet fit really badly by the headlights on this mk8?
