computer.
Is there a way to install a 93-96 computer into a 90? Then have it program to work for my vette?
I ask because I like to start upgrading to the obo2 so I can use the hand held tech. I would love to buy a vette with the obo 2 in it but I got the year I wanted. So, can anyone help me with the above question.

I'm having trouble understanding what you want to accomplish, there are scan tools that will function with your OBDI ECM as well as cables and software to data log to a laptop.
The only C4 computer that is OBDII compliant is the 96, but for it to function and provide misfire and cat efficiency information the 96 engines also have a crankshaft position sensor and 4 O2 sensors. Your 90 has no crank position sensor and only a single O2 sensor, it is a speed density system with batch fire injectors, the 96 is MAF with sequential injection, my guess is that the conversion you want is impractical if not impossible.

For starters ,the LT1 with the Optispark has a completely different spark system so you would have to work around that first.
What is the hand held going to give you that a laptop and software as used on the earlier ECM's won't

The more I think about this the more I think he is talking about the Hypertech programmers used on 94 and up vehicles.

You should also understand that all consumer grade tools and scanning software will only read data from the ECM/PCM. You will need a Tech 1, Tech 2 or other professional grade scan tool to access data from ABS, FX3, or CCM controllers.
