I know I'm probably not in the right place for this question, but I really need some help. I'm building a 1993 roller 350 into a 383 stroker and am looking for a computer that will work with my 4l60e transmission. Can a 1993 LT1 computer run off of a tbi/tpi distributor instead of an opti spark? Here's the frankin combo I'm building it's a 1993 roller truck block, using an eagle 383 rotating assy, RHS Protorker 170cc Vortec heads, a CompCams 08-412-8 roller cam 110lsa .484/.494 lift 212/218@.050" dur. Here's my problem, the induction. I'm modifying a Weiand dual 4bbl tunnel ram to accept LS6 ev6 fuel injectors and dual stripped down 2bbl tbi throttle bodies. I would like to use a 93 lt1 computer if possible because I know it has transmission controls built into the computer like the one in my truck. And I also already have all the tuning software and hardware for datalogging and burning my own proms.

93 does not have a 4l60e, its a 4l60/700r4 and has the tv cable.

To get the 93 ECM (only controls Engine, not Powertrain) to run with the Gen 1 distributor, you would have to find a way to mount the Opti's optical cam position sensor in the Gen 1 distributor. I believe is has been done. Search on the "Advanced Tech" forum. LT1 ECM/PCM will not function without the cam position pulse signals from the optical sensor.

You need a 94 PCM to run a 4L60E with switched converter lockup, and a 95 or up PCM to run a 4L60E with the pulse width controlled lockup 4L60E. Now you're into MAF and sequential injection, rather than the 93 ECM's speed-density and batch-fire injection.
