24x conversion questions --------------------------------------------------------------------------------
I have a 1975 Chevrolet Monza 2+2 with a 383 (aluminum Motown block, AFR 195 Competition ported heads, 74219 Lingenfelter cam, ported Superram, etc.) which will most likely be backed by a Tremec TKO 600 five speed transmission, 8.8 ford 3:23 rear with Maximum Motorsports torque arm etc.).
I want to use the EFI CONNECTION 24x system with the 12200411 PCM and the 58mm Drive by wire throttle body ( which has no vacuum ports).
I am keeping my factory gas tank and charcoal canister. Since the drive by wire throttle body doesn't have a ported vacuum source I am faced with either modifying the throttle body or adapting the Ls1 canister purge solenoid.
My preference is to use the Ls1 canister purge solenoid. I have replaced the 40-240 ohm LS1 fuel sender with a 0-90 ohm fuel sender from a 97 Grand Prix so that my factory gas guage would work properly. Can the PCM be programmed to function with a 0-90 ohm fuel sensor? I will not be using a canister vent solenoid or the tank pressure sensor. If I set the PCM to not display EVAP related codes will the canister purge solenoid still function based on throttle position and engine temperature readings?
