Apexi SAFC2
I was told that the 550's and lexus AFM offset eachother so theres no tuning involved. That i should be able to set Apexi at 0% and run a little rich.
However in order to get my wideband where i want it (most of the time) i am at +20% across the map
The ECU is fighting the Apexi HARD. The wideband is all over the scale. One second rich then lean then rich. I drove home the other night fouling out spark at 8.8 on wideband. While the night before i was struggling to keep it under 17 while cruising....
Any ideas what could be happening?
