I have put a 1994 Lt1 from a Buick Roadmaster into a 1977 corvette. The Corvette has a 4 speed,no air. The setup works very good. My concern is the ALDL1 does not send codes to engine light with paperclip test. The light just comes on along with the fan. Have a Red River cable with Tuner Pro rt. with $EE-16188051-v3.8.adx.and does not red pcm either.Used the Red River Realterm program and everything is fine. Does any body have any sugestions
