I have a 01 monte carlo with a e85 l67 swap that had a 3800. Been driving on the swap for the last 2 years no problems. I need to retire that car because of living in the rust belt. I am pulling the drive train out of that car and am putting into a clean 01 monte carlo with a 3800 as was the same that was in my original car that has the l67 in. My question is can i take my l67 vcm and plug in and not have a problem with the bcm if so what will it do or not do and how to fix that. Or can i flash my file into the vcm in the clean monte and just pony up the 2 credits to do so. I am a little confused about the os from my rusty monte being diffrent than whats in the clean monte because it being a n/a 3800.
