hey guys, i know short term fuel trim is not how to correct a bad mapped car. but i just wanted to know how you setup the single trims like pid kp and pid ki as well as the lambda delay and prop.gaing and integral gain. i run a boosted vr engine maybe that helps. would love to see some examples.

at the moment i run 3,58% prop. gain, 16% integral and a lambda delay of 500-100. i still did not played around with the kp and ki. maybe someone is willing to share some settings.  
thx

Im not sure if short trim on v3 is like short trim on latest v2 but to get it responsive i had to use p - around 30 and i abput 15 with scaling vs air flow about 75%-80% on idle up to about 200% in 150 at full flow.
