Approx. 2% of builds need a Aftermarket ECU, it's generally the tuner who doesn't know how to tune a factory ECU why they go to a x brand ECU because they know/understand it. We have been fighting this for decades with right to repair, where companies won't let you into their computers so your screwed. In this caes it's open source so you can so why bother with an aftermarket one it's pointless. Though you do ride a King Till Monday junk I won't hold that against you.

While i agree you should keep a stock ECU as long it does whatever you want only because of the quality of the circuit, i think you're making it harder than it should be. I've worked on and have an aftermarket ECU and based to my knowledge all your concerns are technically invalid, maybe you think more of the hassle to getting things work, but even a 200$ DIY Speeduino board is more than capable. Like i said i don't disagree but i have some things to point out. 1) Most sensors you have are out of spec anyways and no two sensors are the same, with an aftermarket ECU you can calibrate each one based on their actual values whereas in stock ECU you usually have an expected range or have limited abilities. Also if you want a reliable build throwing a sensor on a plug and calling it a day while having no idea about it is irresponsible, you will see what i'm talking about especially with TPS if you read them on an aftermarket ECU. 2) You can use any type sensor you want out of any car, you can go MAP, MAF, Hall, VR, disable Lamda, disable everything except TPS and MAP, add sensors like FlexFuel in cars they don't have, change ignition type, ignition trigger pattern, and many other things. Also have boost modes and octane modes with the press of a switch. 3) Automatic transmissions are not an issue, most aftermarket ECUs can even be used as a stand alone transmission controller. 4) You can have sensor diagnostics and see logs which are more useful than seeing a Check Engine light and finding a misfire code leading to nowhere. 5) Also most important: With an aftermarket ECU you have the ability to program it easily, you can use the software provided with it, or a free version of Tunerstudio or even open source software for many of things. Don't expect me to pay big bucks just to connect to an ECU, while most stock ECUs have solutions for this, it's not always the case. But if you just drop your car to a tuner and then take it back programmed i don't think you will understand this. I have a lot more to say but maybe for *this specific* build a stock ECU is better, and like i said you should not change to aftermarket as long a stock one has the functionality you want due to ECU quality cause i've never seen an aftermarket without looking a cheap junk compared to a stock ECU, there can be waterproofing issues, interference issues etc. Another cheap and better solution is to find a stock ECU that is tunable and has potential, there are many cars out there having them, and then wire it up to work with your engine just like an aftermarket ECU, it might need a trigger wheel and a few sensors, a circuit converting the RPM pulse for the cluster instrument etc. But don't expect a guy with a 90's car and an ECU with removable chips that you take out to flash a premade ROM using a serial programmer take our advice, or an '07 Corolla when you plan to build the engine and run 3 bars of boost on it.

the humor and jabs at everything are highly entertaining. as a fellow Syd region Aussie Mozzie who's doing a significantly less complicated swap (v6 into manual forester) I appreciate the deadpan honesty that you don't need & won't take dingleberry sponsorships to do a good build. will be definitely keeping an eye out for any bright red shorties that fly past on two wheels, though.

Why use a product designed for user feedback and ease of accessibility with instaneous results when you can hack into an over-engineered OE system that was never designed for the end user to get into and change parameters with unreliable third party softwares for modified engines beyond the scope of the original intended use.

Well you said to correct you if you said anything wrong so ya I what you said was the map sensor i don't think it is that looks like a maf and generally have a temp sensor it could be a map sensor but I haven't seen them in that format

Excellent Presentation. I have encouraged a lot of people to stay OEM ECU instead of Aftermarket especially if not going beyond OEM power. Doesnt mean just because you could put an aftermarket ecu you should. However Aftermarket do provide excellent engine protection and performance enhancing features and capabilities which i believe is best suited for someone trying to push a build to competitive levels.

The old Budweiser commercial made me subscribe 😂😂

It is quite clear you don't know much about ecu's, but in this instance quite obviously when there is already an ecu available to run the setup that is tuned etc and it's a pretty bog standard conversion of an entire drivetrain, it makes sense to use the OEM ecu. Your talk of the map sensor, which would literally take 2 minutes to calibrate on any decent ecu, just shows you do indeed know little. Most are linear, but whether linear or not makes zero difference to your calibration process. Only a complete idiot would check two points and assume the rest. But there are ecu's and systems available to run an engine like that with all the aspects you refer to including talking to the trans, but no, theya re not cheap. And neither would the OEM ecu be cheap if you had to buy them brand new from a dealer. But equally it would make sense to use OEM chargecooling instead of those tiny pieces of shit chargecoolers shown in the video. For all the same reasons you criticise aftermarket, your aftermarket tiny coolers are overpriced, and shit.

The aftermarket ECU guys have been pretty quiet since this video dropped... Just sayin'

Its funny people out side the VAG world really don't know how flashable and adjustable they are . I generally put haltech on stuff because I'm not smart enough to work out factory ECUS . i agree aftermarket ECUS have been pretty slow coming to the gearbox control party I've only seen the real expensive gucci stuff like Syvex motec bosche work with factory TCUs .

Wazzzupppp!!! Nicely done. 👍

no, just no. ahh face tok , everybody with a spinal cord seems to think they have ceased to exist if they aren't 'sharing' there feeble personal conclusion n rationale in the interwad. as if ur cut that the deep fried snickers u had today is the same as everyone else's or we even care u got 3rd degree burns down ur throat. there is way better candies to snack on n don't require skin grafts , you just haven't found them yet, thats y ur sad.. but of course I'm sure you'll fire up you ring light again n tell us all when u do. whoo hoo.

Yeah, sure, but, Why don't you just put a haltech in it? 🥸

Decent rant but unless you shit into a pan during a live video and throw said shit at the camera all while cussing with all ur mite….I can only give it a 4 outa 10 rant points but I understand!!…

The long and winding road to completion. Trouble with 1 off jobs. Have to learn a lot about something probably only doing once. Can't wait to see it on the road. Merry Chrissy, to you and lol, "the net experts".

Great stuff mate! Merry Christmas. Cheers Steve

The AI generated german audio track is painful to listen. So good it`s possible to switch back to the original. Greetings from germany.

I agree with almost everything you said except the part about build quality. Sure it varies from brand to brand depending how much you want to spend, but I am sure any aftermarket ECU (for the most part, a couple of exceptions) is IP67 rated at least for water/dust ingress.

man i feel your words in my skin......i have a volvo c30 t5, i love this car, one of the few coupes volvo made, but it doesnt have the manual m66 6-speed tranny and i cant find one to buy.........it has the aw55 auto gearbox....plus, the car has SIXTEEN interconnected modules for everything you can imagine.....hopeless is the true word for this if you want a manual swap.

Can we all appreciate how good of a channel this is? The guy is a fabricator that is swapping probably the most complicated diesel ever made, restoring the car to a condition better that new, he films himself, does all the editing and on top of that he is bloody funny? Congratulations Sir. Please keep those videos coming.

hey mate, how you finding those SAAS airbox things?

Finally someone on TH-cam is talking sense

For a electricity controlled diesel injection system, a aftermarket ecu is quit pointless! Allot of funky stuff is going on with those modern direct injectors, even gasoline DI. But it would be interesting to see how such a modern diesel engine would act when controlled like a dumb one. How would power and emissions change if you just control injection start and duration instead of those multiple injections and pre injection schemes.

So what I got from all that is that everything is tightly locked up and proprietary, information is not easily accessible (if at all) and you are better off not even trying to decipher all that because everything is set up so you can't and even if you manage to, comfort features will probably go bye bye

Can't argue your points basically anything apart from a port injected engine its better to stick with factory.

Factory ECU's are brilliant. Code support is the key to using them successfully. You can always get spares and they are ultra reliable. Only reason to use aftermarket is if the factory ECU doesn't do what you need.

You spend too much time on comments reading! WTF how dumb is the idea to swap a haltech into a VW. Clearly a keyboard mechanic. I would not even argue with that. I recently cam back to the idea to build a humvee in GER, as a fun rig with some stuff on the tail and a 496 in front of a 4L80 instead of a more common LS. In THAT case a Holley EFI makes sense, in addition to alu heads and a cam. But this is a pretty dumb engine, w/o any boost etc. pp.

Merry Christmas thanks for the content

10:10 There actually are: Turbo Lamik and HTG for the ZF 8HP. But this doesn´t prove you different: Lamik looks to have done a good job, from what I "have read" (what ever this means). But I also heard of cases when these aftermarket TCUs FAIL. And If so, you can get in serious trouble on the street, as well as offroad. This can be pretty dangerous! There is also at least 1 piggy box for the 8HP that "just" translates what the ZF needs to know W/O the setting of a different firmware. All of the above are roughly 1 grand!

Without a doubt this talk was required to stamp out the keyboard warriors. There are very specialised techs in the aftermarket ECU industry, but unless they produce an ECU that is specific for diesel and V10 there is zero chance of getting an aftermarket ecu this anyway? Even the diesel torque tuning place that was a few sheds up from where I worked nearly all of the vehicles came in and had the stock ECU remapped in most cases, reflashed with firmware that then enable remapping or they had a chip installed that allowed bypass of specific functions to be remotely controlled. Almost none of them had a standalone ECU? In fact with diesel engines they tend to go backwards rather than forwards to tune for more hp and torque? As in deleting everything electronic and all of injection system to an older all mechanical style of injection? But no older "V10" style diesels exist that have compatibility with the VW V10? It's not impossible but man it would be unbelievably expensive and therefore not even feasible consideration for anyone unless they are competing in some kind of performance diesel racing? It's certainly not the fast way of getting the Touareg motor on the road that's for sure! Nope, getting the fiddly little glitches removed by a VW hacking specialist is definitely the way to go. I would recommend that you do a firmware dump off the ECU when it gets back so that potentially you can use this to reflash any future replacement ECUs perhaps? I do know that what these specialists do is write data directly from and too the chip inside the ECU. Meaning the security checks are valid as VW when it boots, however those binaries may not remain valid when backing up the firmware? It's worthwhile investigating but the person who did the modifications will likely say it can't be done because they want you to keep using their services in the future 😉

"...because it won't be me who's wrong..." Negative fucks to give 🤣🤣🤣

Absolutely, stock ECU is King. Any aftermarkert Diesel ECU is just for useless black smoke. The only exception is Skynam Sybele ECU but it's French and very very hard to setup, even if proved in Endurance and Dakar.

How much weight you got over that front axle?

i hate locked down ecu's man they take all the fun out of a newer engine comforts and just be a pain all around for no reason... specially with newer diesel engines... why cant i have the sleek diesel with quiet and efficient injection in my shoddy old ass hilux? OH and also no crate engines... maybe i should get an R2.8 out of cummins...

What's the guarantee you will whine less about idiots if I subscribe...........

In any regular use case a factory ecu beats a standalone any day of the week, as long as you can tune it that is. Standalones do have their place though, mostly in the track racing world, Or in very specific Engine Swapped applications. People have even used a standalone as a piggy back to a oem ecu, that could not be hacked. Nothing beats that oem idle and drivability though. I also like Oem gauges and functionality on swaps. I dont like seeing cut up dashes with auto meter gauges etc everywhere. I understand adding like a boost gauge or Afr though.

Well said. Side note, what model cigweld unit was that early in the vid, and do you rate or hate it?

Well put, but won't win over the armchair experts/desktop mechanics who seem to know it all!

NEVER BUY A 1VD SHIT HOUSE V8 LANDCRUISER ENGINE!!! They are RUBBISH!!!!

Fan input is input..... But let them buy a patrol body and a v10 vw engin and let them do it .... Its your build

Merry Xmas 😊

MAB innovation guy 🫡

so your in australia and you modified your car, how do you enjoy your 1 ton + paperweight? please comment below xD

That engine bay could do with some more pipes and cables :) I agree, i think if your trying to do a unusual swap like that you would be better sticking with the factory setup. Although i would not install that huge boat anchor in there and go for the classic 1000bhp+ nissan patrol from saudi instead.

Ducati, GS, Troopy, 76, Patrol, Toureg, Sierra and now a KTM... I hope the RMS brought you a Christmas Card for keeping them in business🎄

Reasonable rant. 6/10. Needs more swearing and to be a lot more shouty.

I wouldn't use a While loop, they're "blocking" 😘

Gday, well explained and it all makes perfect sense, have a great Christmas mate, cheers

Thank you for clearing up aftermarket ecu’s. Looks the the factory unit can’t be beaten with all the research the volks would have had to do!

Would love to hear your thoughts on Speeduino, seems like it'd be up your alley (not for this of course, this aint no VL Commodore)
