I'am using 96530006 Evo8 with 3-port GM.
When i adjusted long time my WGDC tables with zeroed TBEC i receive constant boost (by DEFI ~ 20.3 psi) by all RPM.
But then i have switched in TBEC and my boost began jump between 20 and 21.5 psi. My target is consntant and = 220.
How i can receive constant boost with switched in TBEC? Thanks.


May be i need to do loggs with zeroed TBEC, and then repeat my 2byte load logg in my target?

Yes. Target needs to match the loads you hit/log when the TBEC is zeroed out. When it does, plug the values back into the TBEC.

Thanks you.

you

a) need to make sure you target curve matches your boost curve (or rather the other way around)

b) reduce the TBEC so it makes smaller changes, otherwise you will swing like a *****!

Thanks you.

I have noticed that - very small TBEC changes - possible overboost in first moment, but stable boost then
big TBEC changes - no overboost, but boost can be dangling around the target during all the run

yeah trick is to zero out the big under boost TBEC... so you only have numbers in the bottom 3/4 of table...
