Hey all,

I'm trying to get EFILive V4 to communicate with my 1995 Buick Roadmaster Estate Wagon - B-body auto trans, with a 5.7L V-8: the LT-1.

I can't seem to get the program to read the ECM data. I'm using the 2-transistor type ALDL cable, and have the correct ID Header and Heartbeat Code (for the B-body) entered into the program. But I keep coming up with a checksum error. Probably a timing issue - maybe.

Has anyone ever gotten one of these vehicles (or anything similar) to work with this program? If so, what timing did you use, and how did you setup the program?

This one has me stumped. Any help at all would be appreciated.
Thanks
