How do you tune at 8PSI vs 80PSI? Turbo tuning tips and tricks.
This is just one module taken from a complete HPA course which explains the EFI tuning process step by step for turbocharged, supercharged or naturally aspirated applications.
While the principles of tuning a naturally aspirated (NA) engine are the same as one using forced induction (FI), such as a turbocharged engine, the process you follow does differ slightly in order to ensure you can still tune quickly and easily, but also reliably.
In this turbo tuning lesson, Andre takes us through some of the basics of steady state tuning for both high and low boost applications. Even if you understand the principles of EFI tuning, using a dyno or tuning on the road/track for the first time adds another element of learning you will need to master. These courses will give you the necessary skills to tune any engine from start to finish, step by step. In particular, you will learn:
- How to configure your ECU to suit the engine
- What numbers to put in the fuel and ignition tables before you start
- How to get your engine running for the first time
- How to use the dyno to control load and engine speed
- How to tune the fuel map in steady state
- How to optimise the ignition table
- How to tune fuel and ignition using ramp runs
After completing this course you will have the confidence and specialist skills required to properly calibrate your ECU on the dyno, but more importantly, you will also learn HPA’s '10 Step Process’ which will take you through a tuning job from start to finish, ensuring you don’t miss any critical stages: bit.ly/StartEFI...
Course ownership is FOR LIFE. NO monthly fees, NO sneaky charges for updates (these are free!) and 2 years support from Andre and other tutors are included.

I'm a paying customer and I still watch these whenever they pop up on TH-cam. HPA courses are no joke. The only joke is if you pretend to yourself that you understand what you don't. It's on you to learn what is needed to understand the courses and to pay attention, but all the practical information is there, laid out beautifully with no filler whatsoever.
Thanks mate! Really appreciate you taking the time to share that. - Ben 🧔🏽
@@hpa101 I'm glad to give credit where it's due, and I appreciate that Andre tends to the forums as much as he does.
If I could afford to be a paying customer I would be in a heartbeat. Sadly that won't be happening at anytime in the near future, not in my state of affairs. I'm very thankful for these videos though, because without them I think I would hardly have a clue what I'm doing.
@@TheGreyTest was in the same boat as u, but he offers payment plans
Give this cannel a like. This channel gives out some pretty good and accurate info i honestly don’t think there is another channel like this that puts up good informative videos.
Cheers for the continued support mate! You're one of the OG subscribers too so I'm sure you've seen it all growing over the years without resorting to shallow content which Ben and Andre are really proud of - Taz.
Best interviewer ever
Can you please do a video on the differences in turning a turbo rotary? Especially around the dangers of knock/timing and approaches to managing chasing power.
Talk about blow-by...
You have my respect, my go to channel for anything i need clarity on, cheers, keep up the great work.
Cheers Vivian, glad you enjoyed the lesson mate =) - Taz.
If it's possible, it would be really cool to see you tune/talk about your customer's cars. That car in the beginning looked sick!
Hey Alex, we actually have a video on the R32 and the Focus, but I assume you mean the Focus ;) You can find a rundown here: th-cam.com/video/1JBug4nDRQw/w-d-xo.html - Taz.
I do spend time at the area @3k rpm as it comes on boost as most 4/6 cyl engines will be at that point when on the highway or if they shift down a gear at 80kph and spool it up but dont want to rev the guts out it skipping 2 gears. A lot of tuners around sydney are lazer fkers, just stick it on the dyno and do pulls
Just max all tables with highest value wot. 99 timing 1 fuel. Won't even run so then I can put it on a trailer go to races and say once my tune is dialed in I'm going to smoke everyone. "Needs a tune and should make 1000 wheel"
We've been doing it wrong! Cheers Clayton :D - Taz.
What would be really useful for me would be a video on tuning without a dyno, for us plebs on a tight budget who can't afford it.
We cover that on our website, but there are some videos on this channel on that topic too. Here's one to get you started if you're reflash tuning: th-cam.com/video/yAXhNt_gYjU/w-d-xo.html - Taz.
I’ve just discovered (probably not the fist but I haven’t heard of it before) to increase performance with minimal drawbacks.
Instead of boosting up the torque you can optimise the engine for power.
So for example you have 185 hp (bmw b48) with 285 Nm max torque . Intead of tuning it up to say 350hp max torque and 250Hp max power which increases forces on bearings and rods because of torque you can simply control the tune to keep the 285Nm all the way to 7000rpm this will give you a nice constant torque from 2000rpm to 7000, electric car like.
285Nm@7000rpm is 280hp. Of course you get this power as you can see only if you push the car to the rev limit
The down sides I expect to be minimum only more heat if pushed too hard so for race cars you need temperature mitigation otherwise if the car can accept the normal tune up it should be fine with my version.
Also you can make an inferior setting than a regular 350Nm 250hp. By letting max torque at 285 and allowing it to drop to 255Nm at 7000rpm which gives you 250hp
------------->
So in a few words:
Stock 285Nm max 185 hp max
Normal tune up: 350Nm 250hp max
!!!My tune up: 285Nm max 250hp or 280hp max!!!
How do you increase hp without increasing torque?
@@JoeSmith-jp7bk if you have boost controller ,you can play the game as you want ,torque in low rpms kill the engine and ignition timing is for na engines,if you want power in turbo charger engine you increasing boost not timing...
@@JoeSmith-jp7bkyou can't, torque and power are intertwined, torque at an rpm determines your power.
Can you guys help me set up the vnt stop screw at full vacuum please. It's a diesel engine.
Thank you
I am planning to buy you guys tuning course, actually at the very start of turbocharging my 2,3l mercedes 4 cylinders engine which has a 9:1 compression ratio! I would like to go around 25 to 35 psi of boost! What compression ration should I at!
Good solid advice
Hey nice job as usual
Can you give a lesson on
Intercoolers
If it's a street car, use Water/Alcohol Injection instead,
you probably don't need an intercooler on a street car.
As far as I'm concerned, Air to Air Intercoolers are just a big pain in the butt, and generally
should not be relied upon for consistent, predictable performance, or detonation protection.
Yes, if you size all the plumbing, and the intercooler itself correctly, and insure that you maintain
consistent, and adequate cooling airflow across them,
they will help to generate more power with less boost,
but, they are somewhat unpredictable in performance,
which is not something you want when operating on the ragged-edge of engine destroying detonation.
They are also ridiculously bulky and difficult to install without
huge performance compromises and bodywork modifications.
"Air to Water to Air" Intercoolers are far more predictable in performance,
this is why this is the ONLY type of intercooler you will see on a
factory designed Turbo, or Super Charged, installation.
Lots of excellent info here........
www.rbracing-rsr.com/waterinjection.html
.
@@jimbrown563 Not even remotely true. Water/meth injection isn't very practical on a street car due to the need to fill it up and gas stations don't carry it, intake air temp sensors allow you to adjust for inconsistencies in cooling, and lots of factory turbo cars use air to air intercoolers.
Are you trying to tell me you don't have a Wal-Mart or an Auto Parts store within 5 miles of your house ????
Windshield Washer Fluid is an excellent substitute when you can't get to a Home Depot, or Loews to
by a couple of gallons of Alcohol,
which should last you about a month,
unless you drive around in Boost most of the time, then a 2 gallon tank may only last a week.
And, if you run out, it's no big deal......
so you have "less" Boost until you fill the tank again, not exactly broke-down on the side of the road.
In a more practical world........
If your in Boost on a regular basis, what you actually need is a bigger engine, and,
it needs to have big enough heads
that you really have to try hard to generate more than about 10 psi of Boost,
in which case,
your manifold air temps shouldn't ever peak much above 170F, during the summer months.
If your talking about Daily Drivers, there is a practical maximum Torque Level,
which if exceeded, just results in tire spin, at which point,
I drive around you in my mostly stock S-10 Truck, ( 2.1sec 60ft times on standard street tires).
( this is with a very low compression 4.3L V-6, with a stock cam which came out of an old farm tractor,
and a 3" Cat-Back exhaust, and extensive HPTuners tweaks on the Computer,
and a 3K rpm High Stall/ Lock-up Torque Converter )
( Your Turbo doesn't stand a chance below 50mph without Slicks, ( and that makes it a race car),
I blow off a Turbo Rice Burner about every 2 weeks or so, when I run into them,
with the AC and Stereo on, and with reasonably quiet mufflers, and without ever squeaking a tire,
while they hit their rev-limiter repeatedly )
I get a big kick out of it.
"Traction is Action", so if you're spinning your wheels, you're just blowing cash on new tires.
My tires are ~$200.oo each,
so I do everything I can to keep from unwinding them onto the pavement.
And, my truck is set up for handling, not drag racing.
( The 'Torque Management" settings in the Factory Computer are very useful for
maintaining exactly 0.83 G's of acceleration in first and second gears,
higher G-forces require Slicks, and many drivetrain up-grades )
BTW, I stand corrected on the Factories not using Air to Air Intercoolers,
I haven't worked on a Rice Rocket for around ~30 years, so I'm out of touch on that one.
I'm a die hard GM guy, and the Domestic systems are 95% "Air to Water to Air",
Except for the full sized Diesel Trucks,
which have Intercoolers with twice the volume of the main Engine Radiator,
and enough room for 4" pipes snaking all over the engine compartment.
But when you start talking about compact size cars,
now you REALLY have to get creative to cram 20 pounds of shit into a 5 pound bag.
Like I said..... Pain in the ass......
Shit stickin' out of the hood, and out from under the front bumper kind of pain in the ass.
Especially when it comes time to inspect, or access something, under all that plumbing.
I spent over 2 years as a Tuning Guru, mostly in the Mega-Squirt Forums, back in the 90's,
so I've seen a lot of weird shit,
and assisted hundreds of people with figuring out their tuning problems,
and probably 80% of that was on 4-cylinder Turbo-Charged Rice Burners,
which is why I will assume that's where you're coming from as well.
And because of this extensive background, and hands-on experience,
I can confidently make the statements in my first comment.
I can also be confident in assuming that you have not thoroughly gone through the
web page that I provided a link to.
Those guys use custom made Air to Air Intercoolers and Water/Alcohol Injection at the same time,
but they are setting motorcycle Land-Speed-Records, not driving a street car.
They've been doing this since back in the 80's, and they know what they're talking about.
I recommend that site because my experience agrees with everything they recommend,
although their recommendations are geared towards dedicated racing machines,
not street cars.
But all the rules still apply, no matter what type of engine is in question.
There's more than one way to skin a cat,
but it takes lots of study and experience to always maintain that slight edge on the other guy.

@@jimbrown563 I mean I stuffed a turbo bigger radiator big Intercooler into a 1.6 Miata and that’s arguably about as small as it gets, never turbod a car before and wasn’t bad at all
Do I need tuning up my car after I got instilling turbo kit on it and do I need replacement of the car manufacturer computer?
1.) Yes
2.) Possibly, depends on the application
If you plan on using a professional tuner to tune for you, then they can help you with both of these things and they are the best person to do so as they can make sure they get everything right for what you want to use the car for, your budget, and your timeframe :)

If you think you might want to learn how to tune yourself, then you can start to get a feel for what is involved with some free lessons here: www.hpacademy.com/free-tuning-lessons - Taz.
Hi. Just want to get an opinion. I have an audi A6 1999. It has a slight engine miss since it's AC compressor is too large. The replacement compressor fixed is not an original. Engine is 1.8 T. Is it advisable to do a stage 1 torque or rather an engine remap. The pull is not that great when it tries to go in hill areas. Also is there anyway to increase turbo. This has done around 127,000 miles
Running slightly rich may solve the issue, or Just install a bigger turbo
We need a way to tune without a dyno, like a simulator. Anyone know of any?
dyno is a road simulator , go drive on on the real road if you don't have a dyno its all the same just you get consistent results on the dyno and its not made sketch looking at a laptop on the road with other people out
Also road tuning you domt get power torque readouts, which is the biggest bit of info you need to know to see whats working and whats not
As Jackson mentioned, road tuning is what you're after. Here's something to start you off:: th-cam.com/video/jTxdU-90Xi8/w-d-xo.html - Taz.
The best would be to have a real time engine simulation model, coupled to your regular tuning tool. Then you cold do all tuning virtually without the risks. To bad its out of reach for the non oem world.
Would it be fine to take the engine between 100-200 kpa while introducing load for sometime when tuning in steady state ?
Are you asking if you can steady state tune between 100 and 200 kpa values?
Yes
@@robusttuning942 yes, sometimes that is possible. That is the goal actually. The ideal thing to do. This video specifically talks about why that is difficult to do especially if you run high boost, so it offers alternatives. Try steady state first
Could you use a air compressor with a pressure regulator to tune a car at specific boost?
What? I'm confused as to what you mean?
Christian Fletcher boost builds so instead of waiting for boost to build it’s already being supplied a certain amount of psi. So you can tune the whole gear without any hiccups. Sort of a nice way if you are boosting by gear. But idk much, just a theory
That doesn't make any sense in my head 😂
Volvo does this to eliminate turbo lag. They install a small air compressor which drives the turbo turbine to speed it up instantaneously
@@MrSupermasi yeah but he talked about tuning the engine at an specific Level of boost just through the compressor

Why TF do you have a mic piece?? 😂
You can just hit the mute button if you want a silent movie, otherwise, we use a microphone so that you can hear the audio ;) - Taz.
@@overratedsrtchallenger different types of mics are designed to pick up different ways. The kind they use in the above video is designed to be close to the mouth and wont pick up other sounds in the room. Ones that clip on the shirt can pick up the voice, but will also pick up background sounds, which during their videos where the engine is running, you do not want the background engine and road noise. Imagine a mic that a helicopter pilots vs someone in a studio.

High Performance Academy No don’t get my comment wrong. It good info, it great. It is just the monotone talk. The topic is slow and can drown out. The topics is needed and it great to offer it for education for others.
