Wondering if its possible to adjust the fuel level workable ohm range in my 04 lq9 pcm. I have not yet bought a tuner and an answer to this will likely make the decision for me. I just recently swapped a lq9 out of an 04 Cadillac Escalade into an 86 k5 blazer with a 0-90 ohm sending unit. I need to somehow alter the ohm range being input to the pcm or program the ECM to a 0-90 ohm range. Is that possible? If so it would make things a hell of a lot easier for me. I live in the regulation state of California so this is required to pass our awful smog laws.
