I have a 1999 suburban c2500 with L29 7.4L. I've dug around on here for several days to see if I could find what I'm looking for, but no luck.... but forgive me if I missed it.
Anyway, I want to put the sm465 behind the 454. What I'm not sure about, and my specific question is: Is the ECM going to care as far as making the engine run correctly if I do this. Not worried about speedo or ABS. I shut my ABS down years ago, and I have some ways in mind to deal with the speedo that aren't related to the transmission. All I want to know here, is will the ECM act normally as far as making the engine run if the 4l80e gets unplugged???
