maxxed maf

[jrocstar]

so my car is really pissed right now. we got everythin g all running right but at about 4700 rpm the maf maxes out. i was thinking ls1 maf or resistor to scale down the maf. wondering if anyone turbo'd has any suggestions. we tried to port the throttle body more and move the intercooling piping as far back from the maf as possible but to no avail. we even took it from 15 lbs to 6.5 and it still maxes. and does anyone know what psia our map sensor is? i am told 1 bar but sofar the car doesn't freak out on even twenty pounds but it is showing maxed map at 1500.

Re: maxxed maf

Re: maxxed maf

i am using hp tuners to tune it. it just has too much air flow for the factory maf.

Re: maxxed maf

it lets me bring it up to 16000 but the tables still remain at 11500 how does this correct it?

when the maf fails the pcm cuts IPW 50%...

so you bring it up and disable the code so that maf will not fail.... you then use PE to add fuel

you can also scale the maf from say 10000 HZ to 11500 to add more fuel..... the pCM will use the valve in 11500 for all fueling after it pass's that point

so if you put 50lb/min in the 11500HZ are the pcm will add fuel for that much air.... but you can't have a huge spike in the maf table or the car don't like it
