I had my engine light come on yesterday. I drove home about 30 miles in the rain, stopped at a gas station. When I started the car back up the engine light was on. It gave me the code 107 (MAP SENSOR).

If the map is bad, would it take out the ECU as well? The car ran fine on the way home, But it wouldn't let me clear the code either with the scanner?

I ask this because I have HP-Tuners, and would hate to have to replace the ECU and have to buy more credits for the new ECU.
