92 Optispark delete
Possible to convert to ls coil packs on my 92? New Opti i drove over a puddle and it got wet. So i want to delete the opti with coil packs. I only see 94-96. Someone suggested 0411 pcm swap but i dont think my 92 has a pcm! Anyways is there a way to use the 0411 pcm with my 92 or a way to get the coil packs to work? TYIA.

Simplistic answer.
You can install the LTCC.. LS coil kit.
Unfortunately 92-93 is a ECU/ PROM combo. Unique harness. bonded to OPTI
I believe 92-93 is forced to convert 94-95 then Torque Head or similar kit
Or all out LS harness
0411 is a 99-00 LS3 PCM. Will not connect.

I dont believe that driving thru a puddle destroyed your new opti
unless it was an NOS OEM (unobtanium) optispark, i believe its very likely whatever replacement optispark you bought was out-of-the-box defective

He never said how big the puddle was. And YES a big puddle can drown an opti. Delco or not, vented or not; they all have vent/drain holes and some LT1s are now hitting 30 years old. You think the seals on an opti don't dry out over the years?

Has nothing to do with being 30 years old. It was new and probably a junk chinese one, as the majority of them are. If a new one gets water in it from simply driving through a puddle, unless the OP was mudbogging with his Vette, then the seals are bad to begin with, and its back to being a junk Chinese one.
Otherwise there would be lots and lots of the other cars that run Optisparks sitting on the side of the road also whenever it rained. Driving through a puddle, won't do it. When we bought the car in 2016 we came home through a deluge, 200 miles from home and at that time the 20 year old Optispark didn't fail because it was raining.

I missed the new part,,
Still my TA went through a puddle. It was dark, rainy and I was thinking I was going on a flat surface....then the nose dipped and water was rushing over the fenders. It was for a few seconds. The car stayed running. But the next day the car started but died half mile from my house. It would start and then die immediately. Pulled the opti and it was full of water and oil sludge. Cleaned it out, resealed it, good to go.

If you bury it, of course. A Corvette will suck water up the intake if you are in that deep, being the bottom feeders that they are. Hopefully the OP caught on that, as I mentioned, if you are going to the LTCC, you still need a functioning Optispark.
