One of the main reasons I wanted to do some tuning was to dial in the driveability. Since most tuners don't take the time needed to perfect the tuning under low load. On the mach I have the hpx maf, blow through. And the crown Vic is an 05 so it is a new slot style maf as well. Running 91 and turning up the timing under light load should help my gas mileage and throttle response. Thanks for the good info!
I think I found out the reason my mach has been having issues in the winter.. is its not getting warm enough to go into closed loop so its idling weird and having some driveability issues. (160 inline tstat with a hole drilled)
Plan to spend a lot of time in the low end of the timing table.
Do you guys keep the generic maf transfer functions recommended or do you change it? I heard some people will go as far as putting their maf setup on a flowbench?
