Hello,

The car I bought had already a map on it but then I upgraded turbo and parts for stage 2 with k04-023 over the k03s...

The map that was on car actually had the FRONT o2 wideband sensor DISABLED!! ( dont know why)
I read it and send to a tuner to do a file for me with the upgraded parts k04-023 and to activate the Front o2 too.
But I've been chasing an issue since cause i got no lambda control on block 001 - would give some strange numbers and has strange behaviour ( log below)

I am thinking that I actually find out that the car that was on the map firstly - it was a GENERIC map file...so the tuner did changes over the existing generic map and maybe the Front o2 is still disabled?

Can somebody help and check for me if that's the case? I've been chasing and chasing the issue for almost a year...

Setup:
K04 -023
4 bar fpr
386 cc
kemso lph
3" oversize tip
3" maf
3" downpipe
fmic

Thanks,

You got scammed. Write it off as a learning experience.
Flash stock file and bring it to someone who is actually going to physically tune the car.
