General 2g MAF max hz

[lauj2gdsm]

Like title says im leaning out on the top end 6k-7.5k rpm. my mods are in my profile. i just got one question what is the max HZ a unhacked 2g maf can read.. because once my log hits 2600hz at 6k rpm my afr rises to 14:5. no matter how much fuel i add this is where i break... turbo is on 20psi.

well I think its not your mass air sensor thats the problem perhaps its your fuel pump. I dynoed 520 wheel horsepower on a unhacked 2g mas my herz reading was somewhere around 3100hz.

I've never maxed one out, but I've heard claims that after 2600Hz the readings become somewhat erratic on some 2G MAF sensors, so that would be in line with what you're experiencing. Not my personal experience though, and not to say all of them would have trouble after that point, as evidenced by keltalon's experience.
