J. Fast's latency values definitely work better for my car! When I tried to use the higher values, the AFR was 12.2 at idle... Now, I need to figure out why I am getting misfire codes (P0300) and misfires. It must be the fact that I gapped my spark plugs at .022 and that is probably too low. They were fine with the stock ECU and the SAFC, but I probably need to go up to .032 with the Chrome. My car is a JDM GTO N/A which I converted to TT with 15Gs. I tried to tune it with SAFC, but the timing of the TT ECU does not agree with the 10:1 pistons at high RPMs so I had to get Chrome, in order to be able to correct it. I ran the car and logged it the other day, and I noticed that I got several instances of 1 count knock at 648rpm. I also noticed one instance of 4-5 counts of knock at about 1550rpm. I went WOT TO 4k rpm and did not see any knock in the logs. I am currently running at wastegate boost, until I tune everything correctly, before I raise the boost. My target is 15psi of boost on 93 pump. I am running Evo 560s and a Walbro (not hot wired).Any ideas or suggestions?
