Are you leaving power on the table?
This is just ONE module from a full, comprehensive course.
Optimising your tune to account for your variable cam control system is an easy way to see performance gains where you need them most. In this lesson, we’re going to dive into the PID gains of a continuously variable cam control system which is easily the most critical part of the process as any mistakes there will impact the steady-state and wide-open throttle tuning that follows, for better or worse.
Compared to many closed-loop control systems the process of tuning your PID gains on a cam control system is relatively easy, and in this [#FREELESSON] Andre gives you a step-by-step guide to his processes. While there are some minor differences between platforms, we have to use something to demonstrate this knowledge to you and for this example, we’re using an Ecumaster EMU Black and Version 11 Subaru STi.
NOTE: This is just ONE module from a full Variable Cam Control Tuning course. It doesn’t matter if you have a switched, vernier adjustable or continuous cam control system, as this comprehensive course covers them all along with the impact valve timing has on performance, economy and emissions in both the low and high PRM range.

You asked for more track footage, engine noises and b-roll. We present to you less of these things, in the form of a podcast with a difficult to read logo to boot. You're welcome. Stream via your favourite service here: www.hpatechtorque.com/ And merch yourself here: shop.hpacademy.com/- Taz 👨🏻

We are finally looking at doing more merch, what did you have in mind when you say a 'turbo' hoodie? One with a turbo picture on it, some text about turbocharging, or just one that you can put on really fast while making whooshing noises? 🤘 - Taz.

This is an amazing video, totally hands on teaching of the PID functions. Thank you for sharing this, you are top of the game!

nuggets of info gold here - i was about to take a clueless start on my cam timing settings this weekend and then this appears to tell me how it should be tested - nice - thank you :)

Awesome! What are you tuning? Let us know how you get on 🤓 If you get stuck on anything else remember there is a full course there for you too if you need it 🤘 - Taz.

this was a good video. i don't own anything with VVT, but this could kind of be used for electronic boost control or something similar am i right?

I just revisited this great video again now that i have a car equipped with a MegaSquirt 2 PnP that has PID control. I've read the MS2 manual on PID tuning and watched other videos on how to tune it.... And it appears i STILL tuned it incorrectly. I thought you were supposed to tune each part of the PID until you get oscillation, then back off until the oscillation stops, starting with the "I". Then the "P", then the "D". I started with "I" to actually hit my target. The the "P" to get to the target quickly, then the "D" if there's any over-shooting. Can it be done this way or am i wrong? Thanks Andre and HPA team 🏆

Did you not watch the video at all or? P then D then I

@@nesmio7378 yes, i watched the video. I'm explaining to you what the Megasquirt manual says when tuning PID. Clearly there's a conflict here on how to tune the PID.

@@PANTYEATR1 Is there a conflict? How well did your IPD method work out for ya? Now try the proper method.

@PANTYEATR1 Ай бұрын

@@nesmio7378 sure, there is a conflict. HPA says one way and the makers of MS say another. Is there only one way to skin a cat or get to the end result? Nowhere in my original post did i say the tune is bad. I said "it appears i still tuned it incorrectly" meaning i turned the PID the way the MS manual said to. Now the question is, will one way create a better closed loop than the other?

@@PANTYEATR1 I've never ever heard someone IPD tune a PID certainly not for a car. Look up any tutorial or information video or forum post and it's always PDI. As long as it works it works and is fine.
