Changing chip?

[Corvetteman]

Anyone here who knows whats happened if i put a LT1-chip into my L88-engine?

Prob won't run as LT1 uses different electronics and ECM .
Optispark has different signals to HEI dist
You may be able to take the LT1 tuning parameters ( fuel / spark / etc ) and load that on a chip for a L98

How would one do that, anyway? Hold the throttle wide open and drop the PROM down through the secondaries?

Just kidding. I know you mean "L98" not "L88."

The serious answer is the engine will not run.

Same thing as when you asked on the other forum. lolotfl
Go with a chip made for the L98.

You could go load 89 code onto your chip with slight messaging. That is about the best you can do for doing a copy/paste type change.

Does an L88 engine need a chip at all?

If you meant L98, I don't think it will work well.

The 92-93 LT1s used speed density fuel management, batch-fire fuel injection and a dedicated engine control module (ECM). In 94 the LT1 switched to a mass airflow sensor and sequential port injection. A new, more capable computer controlled the transmission as well as the engine and got a new name: powertrain control module (PCM). Where the ECM held its calibration information in a replaceable chip, the PCM was reprogrammable through the diagnostic port.
