Thread: Maxing MAF what next....

  1. #1

    Default Maxing MAF what next....

    I finally finished a VE tune on this 2000 F-body with that we did a 408 ProCharged motor in. The VE tuning worked out awesome and definately boosted my confidence in Auto VE tuning.

    After VE tuning I reintroduced the MAF and got it dialed in as best as possible. Mainly up to about 9000 hrtz. I then went back to the PE Modifier table and entered the desired AFR I wanted and through in one of my "starting" timing tables. I wanted to confirm the max values of the MAF as the AFR is going 10:0 as soon as the MAF is around 9800 hrtz. I tried leaning out the PE table but it didn't seem to make a dent into the AFR. It started at about 4K with only 4 lbs of boost.

    I don't plan on spending too much time with this tune as I think its time to figure out the 2 bar custom OS stuff! My post was really to better understand the limits of MAF tuning. The car made 585 HP and 565 FTlbs on only 6.3 PSI and a 10:0 AFR.

    I'm I maxing the MAF? Also note the MAF hrtz between 4700 and up was between 10,500 and 12,437.....

    Thanks

    CHeck B5001. The final row of that table will define the point that you max out the MAF... It's probably 12000hz.

    Do you have Cat Converter Protection enabled? {b0701}

    We'll if thats the case.....then the MAF is maxed! Still wondering why it is go 10:1 at high frequencys.

    Yes Cat enable is disabled!

    You are using 100% MAF and nothing on the VE table at those RPMs. It appears to me that those values are just to high resulting in a rich condition. Better rich then lean.
