58x LT1 on Test Stand
This is not an ideal ECM to run in a 93-97 F-body. The LS1 PCM (24x crank reluctor) is much better suited to the 4th gen F-body.

Our business is about supporting engine swaps (and in some cases production vehicles looking for upgrades).
For an engine swapper (street rod, truck, sand rail, boat, etc), the best time to consider an ignition upgrade on the LT1 is before money has been spent on a new optispark, coil, engine harness, and PCM calibration.
If I had a 93-97 F-body, I would probably not bother with a 58x ECM.

That could be fun
