audi has an external wastegate. With PID 0/0/0 it did not oscilate but from target of 300kpa, it only went to 230 and very very slowly.

I can also try reducing the solenoid Hz. According to turbosmart, it should be using around 10hz. If it goes too high it can oscilate. So i will give it a go tomorrow hopefully.

i have found that the dekas have 380 at 13V and 280 @ 14V

this value of 192 at which volt is it referring to? is it 14V or 13.2V?

look for table boost vs tps curve.
If tps weight is set to 0, no affect of tps.

that is different than what Gints said further up.

so if you use 0 for that value, then TPS has no effect on boost? and if 100% then how much does TPS affect the boost ?

for 100% is like is in tps table. If you put 200%, effect is double.
BTW effect is for boost ref DC and boost target.

so to leave matters simpler, its best to leave it as 100% then?

it was and i have seen it being usually 398% for some reason.

does that quadruples the refDC and boost target? what is the point?

i use 20-40%. No surge problems, good spood...

ok, thanks for that. Ill use 100% so that i know that my refDC and TPS are not influencing this anyhow.

MWfire, are you sure about boost target?
IMHO TPS vs  boost target - there is different 2D table. Mentioned value change just refDC. No?

AVP, 0% of this value means refDC directly from table with no changes from TPS position.
With 0/0/0 you have to found right refDC. Looks like it will be something like 80-90% for 290Kpa.

today i noticed that if i use 0 or up to 40% on weigh to TPS the solenoid ticks. If i use 100 or above it is silent.

i guess if i use 0DC on 1000rpm that should also allow for the weigh to TPS to be 0% there.

by the way, with PID 0/0/0 boost target is reached but its much slower than what i had in megatune. as if i have much more lag.
i possibly need to introduce more DC sooner.

ill test it more!
