Hit a snag on dbc on gen 4 engine
E38 pcms don’t support the IAC, TPS connections required for dbc. And I’m not willing to try to figure out a DBW saltwater situation.
So I found the ligenfelter trg-002 which adapts a 58x/4x engine to a 24x/1x harness. You can then use a LS1 stand alone harness and get a pcm from an early 2000’s Ls to control it. I think I’ll end up around a 2001 pcm. I’ll post more data when can on this issue.
