Boosted performance guys, how to see actual AFR at WOT?

xnick101 · 11-07-2022, 04:04 PM

Due to the back pressure from the BP kit, the AFR automatically goes to 10.0 at WOT on both banks on the oem header sensors. Has anyone figured out how to get it to work so the AFR reads properly other than using an aftermarket gauge? I want to be able to use the ecutek advantages such as AFR safety but that doesn't work if it's afr is always reading wrong. I have an aftermarket gauge and it reads it properly but that ecu obviously can't read that.

Is Martin tuning you?

Sounds like a tune/tuning problem.
My aftermarket wideband reads almost identical to the ecu afr reading around 11.2-11.4 at WOT

the minimum it goes to is 10. if you are seeing flat 10 that means you are running richer than that and the sensors or ecutek cant read it. but they do read pretty close to a the dyno wideband.
