Guest thepenguin99 Posted June 25, 2003 Share Posted June 25, 2003 This may not be possable or at least not worthwhile but im posting it anyway. Has anyone tried using the computer/wiring/sensors from a 94-95 LT1 on an older TPI setup? I do not know if it is possable because you cannot use the optispark on an older block. The benefit as I see it if you could get the setup to run would be an innexpensive and easily reprogrammable ecu. Quote Link to comment Share on other sites More sharing options...
80LS1T Posted June 26, 2003 Share Posted June 26, 2003 I really doubt it will work. Heck I cant even use a 94/95 computer on my 93 LT1 !!! You want the easy programming like I do too dont you! Well I think your out of luck. Guy Quote Link to comment Share on other sites More sharing options...
Guest thepenguin99 Posted June 26, 2003 Share Posted June 26, 2003 Well I know you cant just plug one up to a tpi harness, thats not what I was thinking about. I was thinking of using the whole engine harness and adapting the sensors needed. The fuel injection part should be basically the same. The problem I see you running into is trying to delete the ignition because it wouldnt be used and telling the computer what RPM the engine is at.

Guest thepenguin99 Posted June 26, 2003 Share Posted June 26, 2003 because its easy to reprogram when modifying your engine and doesnt cost me $1000 if I can make it work somehow. Quote Link to comment Share on other sites More sharing options...
80LS1T Posted June 26, 2003 Share Posted June 26, 2003 I dont know man, I think MAYBE(BIG MAYBE) it could be done but I think it will cost some serious green$$$ to get everything working properly. With a TPI isnt there only 2 injectors located on top of the throttle body? or am I thinking TBI? Guy Quote Link to comment Share on other sites More sharing options...
Guest thepenguin99 Posted June 26, 2003 Share Posted June 26, 2003 TPI is a 8 injector multi-port setup similar to LT1 injection TBI is the 2 injectors inside the TB Quote Link to comment Share on other sites More sharing options...
Mike C Posted June 26, 2003 Share Posted June 26, 2003 Even the guy who converts the LT1 intakes for use on older motors uses the TPI computer. I think you need a crank angle and cam sensor that are difficult to adapt to the older motors. Actually, the $1000 on a DFI computer and harness will be probably the best money you spent.
