I've been learning to tune myself to avoid the SOS calls to the tuner when we are away. Timing and fuel have been my kryptonite I'm learning a lot through research and watching these type of videos. Would love to get some real knowledge on how to.

[@hpa101]

Good man! Keep at it, it all adds up. This course here is one I would highly recommend for you: hpcdmy.co/efifyc I know the word 'fundamentals' isn't exactly sexy, however, so much is covered in here and with lifetime access you will always have it on tap :) Here's a coupon too: KZbin25 - Taz.

[@BrodeyDoverosx]

Just be aware that a lot of the AFR targets are theoretical. Different engines/setups will require different fuel targets. You know you’ll have it right when the engine has good response (throttle response) and no spark knock. Every engine and setup…and heck …. Every fuel type will be very different. Your goal is to figure out a process and a ball park to get started.

[@mikejovi980]

Am getting high iat on rb25 with a pretty small intercooler like 100% bigger than factory.. Causing knock on pump on a engine of 8.5:1 or less compression.. still making 320rwkw at about 18psi on a gt3076r and 385rwkw on ethanol at a measly 24psi so what you've said makes sense for the most part.. better intake charge temps mean more power. Although to be fair I'm not willing to spend money on intake manifolds throttle bodys or exhaust manifolds so it's running all oe components.. on the plus side I'll see 20+psi by the time a factory turbo sees 7psi

Just had 2 tuners freak out that my AFRs were so lean... They were richer than yours at 10PSI and now they have me running in the 0.68lamda region by 14PSI. Knew something was off with what they were saying...10AFR is ridiculous, right?

such a good video, that i had to watch it again! i have a question on where the "coasting" area would be? I'm sure it could be in the high vacuum area, but I've coasted in the "cruising" areas before. any tips for running those situations? thanks and great job HPA💪

[@hpa101]

I define coasting as being when you're completely off throttle. There's a bit of semantics involved though and you could also call an area where you're cruising and slowing down 'coasting' and wouldn't be necessarily wrong. If you're completely off throttle though then you can disable injection which helps save fuel and reduce emissions. On the other hand if you still require some amount of engine power and you're still lightly on the throttle then you'd want to target your normal cruis AFR - Andre

[@mr.m6691]

@@subyoooyoy no. 😔

[@subyoooyoy]

@@mr.m6691 I think the Dyno is increasing the load/resistance, as he increases throttle.

[@TheRedspinx]

It's the particular Dyno, hub dynos allow you to lock the rpm and check throttle position.

[@hpa101]

Sorry I missed your question, if you search the word dyno on the channel there are a few videos that explain this and other elements of dyno options and operation. This is a load bearing dyno, and that is the feature of this type. You can hold a set load, being RPM here. You can have a hub, chassis or engine dyno that is load bearing. And alternative is an inertia dyno which doesn't hold rpms like this making them only good for sweeping runs. They are an older and cheaper style really, but still quicker and a little more accurate than just road tuning - Taz.

[@194Easy]

Is it good, to set fuel cut at 100-110kPa while tuning turbocharged engine for more safety in this process at the beginning?

[@mackstone5303]

So maybe this is a stupid question but is a lambda value a percentage of stoich like is .87 lambda 13% more rich than stoich and 1.15 15% more lean than stoich or am i way off base?

hi, I enjoy watching your video's and have started making some how to's for an ecu make we use here, and I'm interested in what mic setup you use in car when on the dyno, as your sound quality is good, and all I get is my voice ok until cars started then my voice disappears into the noisy background of the car... Your sound is good. Whats your setup if you dont mind sharing.. Many thanks. Bill

[@danloosmore8099]

Very informative video, obviously the lower the IAT's the better but, how hot is too hot?

[@princesssolace4337]

I got issue in keeping the torque under 500Nm for reliability reason on my 2012 MPS3 .... its using stock k04 with aftermarket down pipe+intercooler and cats delete .... rest of the exhaust is stock at 1.25bar tuned to 100 octane ... i settled at 300hp @ 480Nm .... if I touch 320hp, the torque gonna be above 500Nm ... I use Mazda Edit software to fiddle with the stock ECU. Q - is there away to raised the peak power but keep the torque at 480Nm? ... I'm at lost here

[@rodriguezangel62]

How does this form of fuel tuning compare to using VE? If using a VE model the ecu will adjust fuel accordingly right? Assuming our VE is correct

[@kzz8971]

Hey, do you have any videos on Subaru tuning?

[@hpa101]

Yes, we use a Subaru in a few different tuning examples from standalone ECU tuning to using the likes of EcuTek, COBB or EcuFlash - Taz. PS: This package deal has everything you need to get starting learning how to tune your Subaru application: www.hpacademy.com/hpa-starter-package//?

[@BourneThisWay]

What’s the best way to tune a base fuel map? For example, I have a R32 GTR and I tune the fuel map based on the TPS, but my AFR target map uses RPM/kPa. I’m also tuning in VE mode and my O2 control is set to use both TPS and MAP

[@danronck3636]

Hi there, i got a question, been data logging my factory 1.4 tutbo Leon and recognized that under 100% pedal, throttle position won't go above 88%. There is no knock detectable and the boost is just 1bar on 102 octane. Is that a factory power limitation or just that they have the same throttle body for different engine sizes where it would go to 100% of throttle position? Thanks a lot for the amazing video lecture as usual🙏🙏🙏

[@nicoleibundgut534]

I have heared that some manufatores limit de throttle position to limit power. Is it an electrical tb? Maybe you find a limiter in any settings.

[@comradecrawford3318]

do you have lessons for Hondata and Haltech products?

[@hpa101]

Yes, we have content specific to both over on www.hpacademy.com The Hondata course is in the Practical Reflash Tuning course. The Haltech content is in the Practical Standalone ECU Tuning course This special deal packages both together along with the courses you should take before either if you are new to tuning (EFI Tuning Fundamentals and Understanding AFR) - Taz. www.hpacademy.com/starter-package-with-bonuses-course-series

[@Fayis1341]

28:50 you said 100% pressure but in table it’s 0. What you mean by that ? What is the negative value of map sensor ?

[@paulmickle1135]

100kpa is 0 positive pressure just 14.5 psi of atmospheric

[@paulmickle1135]

For example if your map sensor is inside your manifold behind your throttle plate your sensor could read 50kpa or a vacuum compared to outside

[@paulmickle1135]

It’s a scale where 0 is a vacuum instead of 0 psi

*Has no real interest in tuning* “Cool, an hour long video on tuning. Let’s watch this.”

[@roflchopter11]

Seems like the process of tuning fuel to AFRs could be automated pretty trivially. Could probably do the same with timing. Is that done? If not, why not?

[@marshallbayer7398]

Tuners don't want to put themselves out of business.

[@xxii9911]

What if you are on stock ECU and the AFR map is RPM/Load percent?

[@BrodeyDoverosx]

This is easier actually. Figure out your “NA load cells”, usually 100% is 100kPa but you’ll need to figure that out by assessing your ECU maps or via data log.

[@Staf00plz]

How did you get the car to go WOT w/o revving up the engine?

[@hpa101]

The dyno holds a specific RPM, as requested by the tuner - Taz.

[@boosted1241]

Is there a big difference between cars and bikes?

[@hpa101]

Fundamentally, no. The main differences are 4 stroke vs 2 stroke and gasoline vs diesel when it comes to EFI. Even when it comes to piston engines vs rotary the tuning fundamentals remain the same, the application of them just changes a little - Taz.

[@stewartrhaines]

When setting up your tune at 6000ft altitude, would 81kpa be your transition zone instead of the 101kpa at sea level? Thanks for your help!

[@JohnDoe-mx1sq]

I know this is a year old. Absolute pressure is absolute. If you've accounted for the extra heat from compressing the air it should be no different at 100kpa from boost or the atmosphere.

[@boyorougesauvage8584]

could you put time stamps please ? very interesting but it would make it easier to navigate through the whole hour

[@MrJoubert1]

why would a tuner remove boost pipes & tune ve table first, explain this pls. also why it applies to alpha n more?

[@BrodeyDoverosx]

No boost, let’s the tuner develop a working VE table for the engine itself. This will let you “see” the efficiency curve of the engine…You can extrapolate that “up” when you add in the turbo.

[@mr.m6691]

Is there a reason for AFR to change based on gear? I recently starting messing with my car under boost. I have it 10lbs in 3rd gear full throttle 6,000rpm its 11.1 AFR, but same condition in 4th gear the AFR changes....

[@ndog1234765]

My guess would be a change in engine load and a slight rise in boost during the shift

The last step of a dyno tune is to confirm your results on the street, or the track - Taz.

[@dtetizada9310]

how could the engine be sitting at 2.5k at wide open throttle? The dyno was applying load or de ignition table wasn't fine tuned enough so there cant be acceleration?

Love you back! Cheers for the support 😎

[@JaydenET]

If you optimized only the timing of a car on pump gas and saw torque gains, without changing the fuel tables (or on a standalone Ignition ECU), does that effect fuel economy? In this case would it actually improve fuel economy, because you're making more power with the same amount of air and fuel? How often is it that you can see torque gains from just timing adjustment without increasing octane?

[@konradnee844]

Yes obviously the engine is producing more power with the same fuel as the ignition event happens at a mechanical superior point during the rotation.

[@SLYDIT]

Do you set a target afr number flat across the rpm range for a given load, or do you adjust it richer/leaner when going through some motors "torque hump/trough". Or is adjusting timing more important for that? Hope the question makes sense.

You may consider a mic that isnt so close to your mouth or another style of microphone. As someone with an unreasonably disgusted reaction to mouth noises, it has made it close to impossible to watch very many videos. Just thought I would mention it since I can't watch the bulk of your videos due to the mic on the mouth. A lapel mic may be at least a step in the right direction. Keep it up though. It seems like good content from what I have seen.
