Yeah its a 1989, I know i have a MAP sensor, and a single o2 sensor. I was planning on hooking into my MAP sensor simply because i have a MAP sensor enhancer at gives me more control over the signal at different speeds and conditions, opposed to an EFIE controller i could get.
So just to be blatantly clear. I need to adjust the signal from my map sensor by tying into the signal wire that goes to the computer inside my truck. The Computer itself is a simple preprogrammed data table that reads data from the map sensor, o2 sensor and uses speed density fuel injection to determine the right amount of gas to put in the chamber. NOT A MAF SENSOR OR OBDII. as for my o2 sensor i can leave it untouched.
Dose that sounds like the right idea/setup?
Once again thankyou very much for your help
