Mass Airflo sensor indication

Post by chuckr4258 »

I'm new to this and loaded the files for my 1986 c4 corvette.
I'm having trouble resolving a code 33 high MAF.
The reading I get from the tunerpro RT point list has no units, mine shows numbers like 2800 thru 10,000+ when i run the engine, and never goes to zero with the engine stopped.
How does this relate to grams per second?
Has anyone had any luck resolving a code 33, I have replaced the MAF sensor, the relays and the ECM.

Have you checked the wires to ensure they are not shorted or weak?, maybe bad ground in the circuit, sounds like you have replaced everything but the wiring.
