Low teens with more boost and mine only wants 10 stock. Something is no bueno! I know overly rich is bad, but what is overly rich? I have seen stock tunes running 10.8 AFR, so that would be a lambda of 0.76 on these. I am a little leaner than that. Wait a second, I just looked at the last log with the crazy 7.5 knock and it had the Lambda at 0.70! Holly crap. That was super rich. 9.85 AFR?! How did it even run with that?! the Lambse was right there so it is measuring exactly what is commanded. What makes it command such a rich mixture. When knock is sensed, does it only retard timing or does it add fuel too?
The turned way down aftermarket test tune I ran was at 8.00 in the middle of 3rd at 4950rpm with knock at 4.25. Lambse and Lambda were all at 0.82, so a much nicer AFR. kPA was 201. It was still pulling a ton eventhough the tune had it turned way down. At 5000 rpm still in the middle of 3rd gear, knock jumped to 5.75 and advance dropped to 6.50. So, even with a good AFR, it was still sensing knock with 8 degrees advance!
I ordered some Torco! I just want to see if I can get the knock to 0 somehow.
