o.k. guys,, what would cause a mafs cel with my mapecu. all the connections are hard soldered. everything is connected within 2 or 3 inches of the factory ecu.
im getting a reading on my logger that shows a mafs signal,, and the cel doesnt immediatly come on,, i have to drive for a minute or two first.
imm getting a tune tuesday and need to rid myself of this light.. any help or advice appreciated.

thanks,, kennedy

Are you feeding a IAT and Baro signal to the ECU?

yea,,, but i think its throwing a baro cel to,, it shows it being stored, but not active. the only active is the mafs cel. good ait.
its weird though, because my logger is showing a maf signal.

Are you sending a static voltage signal for the Baro and IAT? If so, what voltages?
