STFT not matching up…
 

Hey everyone. Having a hell of an issue getting my gtm stage 2 sc tuned.

Using ecutek - put the kit on. Tuner thought my 650 injectors were bad. Put in my stock ones - and it idled properly. Bought new 1300s - car idles lean and my stft banks don’t match up..vary around number wise 110-125 ..more on bank 1.

New tune made - put my stock ones back in and now it runs so rich it won’t idle on this stock made tune. My stocks are rich af and my 1300s are lean…and won’t stay stable..any ideas for me here??been struggling for a month…I haven’t done anything besides change injectors so things haven’t been messed with between each tune. Just a new rom or swapped injectors.

Is your tuner scaling the injectors within Ecutek correctly? Are you on E85?
