Is there a way to make them run lower WGDC; something like a 40% or even 0% to avoid any overboost before reaching operating temp. I would be very insterested in that. It will help a lot specially when my wife for any reason has to borrow my car. I try to avoid that like the devil to the cross but sometines it happens.

and the "Max WGDC cold engine / CEL" table for your specific ROM ID

Did you change it to 0% from 62.5%?
yes you can change it with the table mrfred found here:

Any other ideas to enable the low WGDC when cold?

Also, I noticed the error correction will hang onto the last known % adjustment until it sees a change, so if I was at +4% correction at the end of a pull...then I cruised....then got on it again it will start the next pull at +4%. Is there any way to have it reset the correction value after it sees the load or tps drop below a certain amount so I can start 'fresh' with every new pull??

I believe its a 03-04 thing. 03-04 also keep WGDC at 100% until a certain point unlike 05+ that keep it at 0%.
I tune all ECU-boost cars with the upward correction set to 0. This makes it so it will only add WGDC to get back to target base WGDC and nothing more. No overshoots, etc

That´s the same thing I´m doing. It would still be nice that the correction would reset after every run when your map is fine tuned.

You are the race track, 5th gear in the long straight, load overshoots by 15, WGDC correction goes -10%, next corner you´re in 2nd gear and it´s way under your load target, you lose time and power until WGDC correction actually gets back to baseline since usually upwards corrections are more moderate than downward. If it would just reset after the "episode", I´d be happier

What this means is that you can make the upward correction in the TBEC table **very aggressive** and you never have to worry about overshoots or going above base WGDC. This way it will instantly correct back to base WGDC at that certain RPM if you have a negative correction and are then under target load or PSI.
You could put +50 from -2.5 to -20.0 in the TBEC table and it will add as much WGDC as possible (up to +50) to bring it back to base wgdc (very quickly as well) and nothing more.
I've tuned multiple NASA Time Trial, Autocross and Time Attack evos with this method, some of them have broken many track/course records in their class. If tuned correctly, It won't be the ECU boost error correction making the car "slower".

Hate to revive an old thread but has anyone figured out the correct table definition for the wastegate solenoid activation RPM for the 03-04 ROMS? The 05 ROM makes total sense. The 94170008 and 94170015 ROMs do not make sense as far as the deactivation rpms.
