AFR levels and timing
couple of questions in regards to my modified CLS AMG with the M157 engine:
*I am logging my car and seem to be at about 13.3 AFR. Is that too lean? It also goes up to 30 when I am off throttle and decelerating.
*The timing seems to advance up to +/-30 degrees but seems pretty dead nuts at idle.
Thanks for your input and am happy to provide more info if needed.
