An other weird question... LT1 ECU on a TPI???

[X-cabsquarebody]

I would prefer the LT1 ECU over the TBI. I got the ecu from the car that the trans came from. 94 can be flasted from the aldl port. Would love to know more on making it work.

On Facebook, a guy install a Vortec 454 multi port injection on an earlier big block. He had posted a video of first start up. I asked if he was running a marine ecu, and he said he got the wiring and computer from Temp speed shop. That it is a lt1 Corvette computer. He didn't have a crank sensor. He doesn't know enough to give any deals about how they made it work.
It looks like its been done, just can't find how its done.

the lt1 ecm requires encoded cam position pulses from an optispark for timing reference. it doesn't use a crank sensor. most other ecms use either a hall effect thing or a different type of encoder wheel; the optispark wheel is unique. again, you'd either have to gut an opti to get the proper wheel and sensor, or figure out how to convert signals, which is a huge job.

You can do it all bolt-on parts if the timing cover from a LT1 will fit on your engine. I have no idea if it will fit or not, but if it does you can then add the cam/cover/opti-spark etc to get the signals the ECU needs. Otherwise, you need to fabricate a pickup in the distributor or on the end of the camshaft that gives the correct pulses for the ECU.

you'd have to gut the opti and still run an ordinary distributor somewhere else, since a traditional SBC waterpump wont clear the optispark cap. then you'll find the LT1 waterpump can't be used to get around that, it's shaft drive and reverse flow...

You can get water pump spacers.
