	boost request « on: May 05, 2021, 02:26:59 PM »

Why do I get different boost request if using fixed wgdc or not?

When doing linearization runs I get the boost request desired but as soon as revert CWMDAPP to stock boost profile changes and can not get it back to where it was.

Could it be camshaft angle? but why it messes before and after the switch? only had issues if it before the cam switch point, not after.

I dont even really understand what you are asking ? Are you asking why are you getting different boost request with cwmdapp / ldrapp / fixed wdgc vs normal run?

Yes, I adjust the request during fixed wgdc runs, but as soon as set cwmdapp to normal boost request lowered and can not get it to where it was, hbn is not limiting it and it is not responding to ldrxn changes past ~4500 rpms

You didn't log any of the other load -> boost path caps/scalers (including nws). Why guess?

More importantly, why does it matter?

There are differences in the way req boost is calculated. If you find out what it is, what will change?

Just add or remove load request to get what you want.
