thanks a lot mate!

one doubt, the 88590715 is only for usdm evo 9 or can be adjusted also for edm evo?

i try to flash it in my evo and the car go smooth,with no problem.

If you push down to the floor the throttle, something is wrong and the car is like on off...(i have not log it yet)

With 88590714 no problem instead.
Can be 8859015 is only for eudm?

Hey sorry for bumping an old pic, I just wanted to give an opinion about holding 100% WGDC longer in the low RPM areas of the lower gears... I see some people who tune their BWDGC settings like this. It's not 100% safe. If the driver climb on a very steep hill or feel ricy and do brake boosting with this map, the car will overshoot for sure. Example: You brake boost at 3500 rpm in 2nd gear, bwgdc is 100. Even on stock turbo it could reach over 30psi. BEC could possibly be too slow to counter this.

You'd be better to tune more safely and use the "WGDC 100% under this load" map. This map is there for purpose. I'm pretty sure that boost won't come later in lower gears if settings are on target.

That table isn't a perfect solution either unfortunately. If you're road-racing/autocrossing you don't always want 100% WGDC, and that table can make the car buck if you're at part throttle and just around the load threshold. Not good if you're trying to smoothly accelerate out of a turn.

Ok! I understand that sometimes it isn't the best solution

Edit: But a properly set TPS WGDC correction would not help in conjunction with that table?
Edit 2: I answered myself: there will still be some big changes in WGDC if you are around the load threshold...

So there is no "best of the two worlds way to set boost" in this case.

Unfortunately the "WGDC = 100% under this load" table takes precedence over the TPS WGDC table. So it becomes useless if you activate the 100% wgdc. If it didn't, then yes it would help a lot.

Thanks, I didn't knew that. Yes it would be great if the two tables would work in conjunction with each other. Considering that, I understand that the "WGDC 100% under this load" table makes part throttle surging worse.
