Default P0102 help
Hey there I have a 2006 corvette base that I just put a 408 stroker in and a procharger on. I just got a base tune and it’s throwing a p0102 code and I’ve replace the maf, checked wiring, checked voltaged and checked the fuse. Everything is good. When I log it the maf stays ar 1.46lb/ doesn’t move then the car stalls out. Is this a tune issue or something else?

Do you have a MAF that supports the boost level?

How EXACTLY did you check the wiring ??…all three…MAF sensor is normally checked in grams/second.

Would that cause the car to run then stall out when idling. I haven’t even been able to drive the car yet

pulled back the wire loom to make sure there was no cuts in the wire, made sure that the pins were connected into the connectors properly, the tested the voltage of each wire, yellow the signal wire was reading 5v, pink was reading 12v and the ground was 0v. Then tested the fuse.

If an aftermarket MAF sensor that would be suspect…I like checking the MAF using frequency or with a scope and seeing a digital 0-5 volt square wave…ground should be checked with ignition in run…less than 100 millivolts is a good ground.
