Hey all, Im new to the forum, however not new to the grand prix or cars, straight forward question here, the Evap system on my car though I realize is not likely to cause any real performance issues, does from time to time trip my CEL and what not, the system doesnt bother me, however I dont care if its working or not, so, I believe Ive worked out a delete for the whole thing, never have the ecm run an evap test again, some if not all evap tests only run if the tank is between 15% and 85% full so my idea, is to trick the ECM into thinking the tank is always 100% or 0% by inserting a fixed resistor in the sensor circuit 40ohms would indicate to the ecm that it is empty and 250ohms that it is full, or visa versa, id have to look it up, regardless, easy fix right, the slightly more difficult question and the thing Ive been pondering is how then to bypass the ECM and connect the sensor directly to the IP cluster, it may be as simple as doing exactly that and wiring straight from the level sender to the IP, idk, I havnt been able to find much info regarding the signal sent from the ecm to the IP Im probably going to bust out my multimeter and see If I can work it out, but In the mean time, any suggestions or ideas?
Also this is on an 02 GP 3.1L
