with the exception of sometimes seeing lingering kr after forced downshift/throttle stab, the only knock counts I see are at startup.
I am talking about following father time up the interstate on ramp and he wants to merge with 80+ mph traffic doing 45. Stabbing the gas and passing gramps will occasionally generate counts/kr. I think it's an artifact of lugging while the trans decides to downshift plus the burst knock function. I don't drive it like that much and will manually downshift to avoid lugging the motor 99% of the time.
laptop temporarily down - IIRC it's all in b4 3k rpm.How quickly do you ramp up to your full 30°? As you can see on mine, I don't reach the full 34° until 4800 RPM, so at say 3200 I'm only at 27°.
actually tuning for consistency while looking to improve ETs too (and keep respectable mpg). A lot of back and forth on timing and afr in the beginning. Timing first, then afr, then back to timing - lather rinse repeat.Did you find that optimum AFR just by what was fastest at the strip? Did you play around with timing at all at the different AFRs?
I bracket race the car so finding that last .05 sec. doesn't mean a whole lot to me. It's slow and I know it, FWIW I don't need this car to ever go quicker than 13.50.
trans or valvetrain noise, mine does the same thing. 99% sure its just valvetrain racket on mine...My car's fairly loud, but not bad. The Corsa mufflers seem quieter than Magnaflows/Borlas/etc. It has a bit of a rattly noise at low RPM and high load, but I'm 90% sure that's just transmission noise (knock sensor doesn't pick anything up). I'd been running it on 91, but since I drove it out to the east coast I've been using 93 octane. I haven't been able to take it to the strip out here, but it seems to run the same. Looking at my datalogs, the occurrence of low-RPM knock doesn't seem to have diminished, and I was/am seeing WOT knock so infrequently it's hard to say if the 93 made any difference.
Actually, I'd forgotten that, but the low-RPM knock was there before I did the header swap.
