Title: cwmdapp AFR! Post by: Renegade187 on January 24, 2026, 09:34:21 AM Hi guys
I have been trying to find the right duty cycles for my GT28 setup and I am struggling. This is a 2 year journey and I am at a wits end. Numerous flashes and I just cant get it right. I am now trying the CWMDAPP to 8 and to log the DRAPP at each DC %. When I activated this, the AFR dropped to 10 and I an scared to drive the car with this low a AFR. I have tried doing this 2 years ago and now again. Please HELP Is it fine to do the runs at each DC % or is my concern valid? Surely other who have used the CWMDAPP function has some experience to share please Title: Re: cwmdapp AFR!

i actually found the problem the map reference was off by 1 position i.e -1. Change the reference to 1 forward and found CWMDAPP. The previous map that I was changing did in fact switch off the lambda coordination. Dialling in KFURL for a big turbo and I off to do the linear runs for the DRL! |
