New CL Boost control code for MS3/MS2 experiences?
@Brain and all MS3/MS2 users.
With the new code 3.0.3u they backported the boost control code from MS3 to MS2.
It is supposed to react better to changes in boost and to bring it to the target better.
I asked at MSextra.com how the tuning procedure changes and Ken answered the following:
You should still tune "P" first, but the number should be much lower than before... maybe 10% or so instead of in the 100's.
Then add enough I to get you to your target. However, when you add I, you'll probably start to overshoot. You'll probably have to double the P term once you start tuning I.
With P and I tuned, you should be overshooting slightly then leveling off right at the desired boost.
Does anyone (Brain?) have tried this already - (And what are your settings)? I have to tune my bost control anyway due to my new turbo so I would like to try the new code...
Use a small amount of D term to compensate for that overshoot.
