Car has a large whipple, monoblade built motor etc.. I have it tuned well other than the occasional engine failsafe mode when taking off from a stop with light to medium throttle since changing from a 127mm maf tube to a 148mm for more range. I have tried everything I know of to cure this. The only thing I think I might have missed is a light maf voltage oscillation I have at low load with the 148mm maf tube that I didn't have with the 127mm. Any ideas? Also, is there a way to filter this oscillation out and how to do it? Thanks
