Knock is unusual on a E map, especially when you have good timing. Its possible your E% is higher than you expected, and/or, IATs are lower than what you had when running this map previously. Both are big factors in HPFP crash. You can dial back your E mix quite a bit and see if you can run the map with less ethanol and get clean timing, or just run a pump gas map.
yeah e% was way off. I added 5 gallons of 91 after this log and it was still crashing. I siphoned some fuel from the fuel rail to test the e% and it was at 35% after I added the 5 gallons. I’m dropping the car off tomorrow to install the new hpfp and ps2. I just wanted to make sure the car was running right for the before dyno pulls.
