Low MAF Readings at Idle

[Terbro]

Check my sig. for mods...I'm seeing MAF readings of 2 and 3 at idle. RPM's are fine, IAC is fine (18 last time I checked). TPS is 46 at idle.

I believe this started after install of the new motor. LT1 MAF is only a 18 months old. Homemade 3" cold air filter.

Any ideas?

If you're using an extender chip, then its perfect, since it will be half of what it normally is. If you're not using the extender chip, then something is amiss, but you may be able to tweak the idle setting in the translator box.

Eric, you're beautiful. I just got back to post my findings. Those being that I swapped out chips and determined it was the extender chip. Exactly...the highest WOT value I saw with the ext. chip was 134. Put put in a normal chip, MAF readings look normal, performance COLOR=red]STUNK![/COLOR]

So, my question is, why? Oh, I just remembered...the ext. chip halves the values so that it can read beyond 255. Bingo, Roger, and got 'cha.

Thankage,
