Hey guys , we build a 1970 chevelle with a Lsa/6l80 from a 2011 ctsv. It?s wired with a e67 Ecm and t43 Tcm. I?m using the sft-5000 and approiate harness from zero gravity performance which is just a late model gm factory shifter from a Malibu I believe. I?ve got the correct wire in pin 7 of the tcm harness connector and have been playing with the tcm tune for days trying to get it to work in tap shift mode. When I pull the shifter all the way back the pcm sees that at m5 and I have the range active set at m5 to supposedly go into tutd mode when it sees that . My shifter has PRND5 . When I pull it all the way to 5 that?s what it shows in the tune software. I?ve read several similar threads here about this and copied what people have been doing in the tune to get it working with no luck. I?ve seen that some say the tcm needs a tune from a vette so I copied all that info over into the tcm tune also. Even just read someone say it Caint be done with a e67 but some say it?s possible. Just need some advice to help move forward.
