    88 Monte carlos LS1 painless wiring harness

    hello. i was wondering if i could use the hptuners programing and if it will work on my car. i have an 88 monte carlo that i put a 98 LS1 motor with the 4L60E tranny. i couldnt get around the vats and a couple of other things so i bought a painless wiring harness for the LS1 98-99 vehicles. i dont have rear o2s and i have about 15 codes all for stuff like fan air pump gas tank press and stuff like that. can i edit all this out with the hptuners programming. and will it work on my setup i dont have a bcm either, do i need a bcm for the tuner to work. any info would help alot thanks joe you can email me at [email protected] thanks guys

    HPtuners will work just fine for your application. All you need is the VCM, is it from an F-body application (the VCM)? You might need to know that.

    As long as you have the ALDL port, you're good to go.
