Setup
91 b18a hatch t3/t4 turbo with dsm 450 injectors.

We have tried uberdata 1.8, 1.7, 1.6 and on 2 different good working ecus from different cars.
Car will read 9.6 - 10.6 a/f on the wideband.
If we take away fuel the car runs richer. 9.0 a/f on wideband.
We pulled a spark plug wire out and the car got leaner? WTF?
We tried a new map sensor, new thottlebody/tps.
I really dont think its uberdata because like i said i tried multiple maps and I've had 450 idle with no problem before. I think it someting with car. Any suggestions?


Thanks in advance Josh
