The stock ECU has gear dependent boost control!

Yeah, I was thinking last night after I signed off that you might have erased this stuff. As razorlab said, I'm not sure how many people will use it. I'm kinda thinking that I will set up different boost control maps for 5th and 6th gear. Or maybe I'll do what razorlab said and set 1st/2nd for more boost for entertainment.

Wow mrfred, this is amazing. Tire spin was becoming a problem in first gear and even second on colder damp days, this is really going to help a lot on the street AND at the track. I can now set up friends cars and really limit how much the drivers emotions mess with clean passes. Just line it up, drop the clutch, and flat shift down the track.

are the values the boost control duty cycle?
for example, on the 2006 EVO IX GSR/RS section
5th gear by 7500 rpm has a value of 161.1.
Is 161.1 the boost control solenoid duty cycle?

For anyone looking for this: the scaling is the same for everyone, the table address is the address of your existing "Boost Control Limiting Vehicle Speed" table.

This is awesome. I'd say its especially useful for people running the load targeting rather than the JDM map and PSI targeting. I know my car hits totally different boost levels in 4th than it does with third since the load values change and the ECU tries to hit my taget load values in my BDEL table. So there were 4 BDEL and BWGDC tables originally right? So now only 2 of them are proven to do anything?? Sorry, trying to catch up here.

Your Avatar says you have an Evo IX, but it sounds as if you are asking about an Evo 8. Either way, there are only two sets of tables that are used. For the Evo 9, its set #1 and #3. #2 is never called by the code. For Evo 8s, I'm not sure which two of the four tables gets called because I've never bothered to go through the boost control code in detail on an Evo 8. tephra might be able to answer, but otherwise, I recommend figuring it out by trial and error.
