	Boost Requested Blips down around 4000 RPM « on: June 02, 2020, 11:36:51 AM »

Simple ME 7.1.1 stock turbo, stock fueling, cal.

I have everything but some onset overshoot sorted out but this weird blip where boost comes back up a bit at 4000ish RPM.

I've attached a log and my LDRXN values, if anyone has a suggestion I'd be grateful.

Also, fix your overshoot.

You really ought to log your PID variables when debugging boost issues
