85 mm ls truck maf gen2 setting

[terry richards]

Have been using 4 inch mega maf for last 10 years but had to use tornado in front of turbo to stop maf back flow that caused erratic idle and dying when letting off gas quick. Bought 85 mm truck maf Delphi 10043! Set gen2 maf in to ls1/ls6 85mm starts and runs fine at idle and low speed but bucks and goes lean at anything over 2 volts on tps. Same thing with 3.5 lt1 and ls1 aluminum setting. Tried a different 10043 maf same thing. Runs good when I go back to stick type maf.

The only thing I should have to change in the translator is the first page in configuration witch is maf input. Ls1 aluminum has a 13.5 to 14 F air at idle but bucks under any load. Ls2 to Ls6 85mm has 17 F air at idle and bucks under any load. I wouldn't think I should have to add 30 or40% to get driveablty. The stick maf drives good and runs med 10s at 128 at 24 lbs with the tornado in front of turbo and fuel taken out. You think I could have 2 bad Delphi mafs ?

No idea. I don't run Gen2. It's way to complicated. I use Erics chip and the Translator. I use the Keep It Simple Stupid approach. PM Turbobob.
