MAF configuration change

Post by jj205mi »

Was having my Car tuned on the dyno and had the maf setting as HPX N1 Low load 500hp, well we maxed it out pretty quickly

So went to change this as it is in a 3” pipe on the cold side of the intercooler piping. Switched it to high load and the car runs very poor (I’m guessing because it has thrown everything off now) do I need to start from scratch with a new tune? Or can I save some time by some other means?

Sorry for the delay with this one (been away). You will need to re-adjust TIM to get the base mixtures @ 14.7:1 AFR at cruise (2000rpm) and the K constant so that you operating in the full load range of the fuel/timing maps
