Check engine light with VPC

[Wishingforagsx]

I installed my VPC, and the check engine light came on. Autozone checked it, and it said something about the MAF. I lost the manual for the vpc, so does anyone have this problem or a copy of the manual they can send me?

I am not sure that VPC manual would help you much here. You have two possibilities:

1. VPC is not configured right for your car, its signal is so OFF that it triggers the CE light (wrong setting and or chip).

2. Problem with ether VPC MAP or Temp sensor.

I would first make sure that everything is set right and if it is, I would borrow someone else's MAP and Temp sensors.

I bought the chip for a turbo upgrade and fuel pump, do you beleive that i could add injectors without the cel coming on?

did you hardwire it or use a harness?

You have a bad connection or bad resistor(s) in your wiring harness. Check your airflow wire from the ecu. Here is a diagram for 91-94 vpc ecu wiring.
