Prom Style Computer
Has anyone come up with a replacement programable computer for the old style prom computers where you have to take the prom out and have it reprogramed like I have in my 92. Had I known that when I bought it, I would have got at least a 93.

Haltech does have a support article about the LT1, but basically they tell you to go ahead and wire it yourself. If you have patience, that's not actually that difficult a job to do, and they do give you instructions. But it does not appear they have any plug-and-play solutions for the LT1/LT4.

I know EBL is available for TPI Corvettes. How did the CCM/ECM arrangement change? 92 LT1 is still OBD1, Batch Fire, 700R4. It is basically a miniram TPI with a distributor in the front rather than the rear. Although, I know the Corvette had some functions the F-Body did not. It is dang near plug and play but if the factory ECM has code for the CCM I am not sure that would be supported.
Dynamic has a list of compatible ECMs, that is why I was curious what the ECM number is and if it is listed as a "compatible" option. There is some re-pinning of the ECM harness, but it isn't bad to get one in. Then 8 frames per second data stream, data logger, and flash based memory ready to go. Works on GM .bins so there is a lot of support... all good things if it is compatible.

Since the OP is addressing 92, the only thing I find annoying is going under the hood of my 90 to change the tune. Suppose I could hook up my Ostrich but I still need a longer cable! lol

I used to ride my bike everywhere, then I got a license
I used to talk on a phone with a cord attached to the wall... you see where I am going with this?
time has passed, technology has improved and faster data logging with flash based tuning is just quicker and easier
It would appear dynamic doesn't support a plug and play option for the 92. In which case, I would be looking at the ostrich.

You could change PCM and engine harness.to a 94-95 SFI. If you have M6 it's fairly simple. Lots of 94-95 LT1 cars including full size. Use MAF or tune it for speed density. Automatic will be more complicated because of different type of shifting. 92-93 cable.94+ electric.
