Hold-up a minute... I just remembered something critical that severely effects why your swap wouldn't work:
When the engine was redesigned for '98, the triggers on the crank-trigger wheel were advanced several degrees to cause the injectors firing time sooner to achieve better mileage. This alone will cause trouble for those that swap a 2200 into a 2.2L app, as the computer (unless it's been reprogrammed) will still think it's seeing signal from a pre-'98 crank. The result is the spark comes too-soon & the engine fights the resistance resulting from it.
BTW: You did use the ICM off the '95 engine with this swap... Right?
It won't keep it fropm running. I have done this swap. We put a 01 2200 in a 96 cavy. We used the 96 ECU, wiring harness, just adding the 2200 injector harness. Car is still running around on the 96 ECU.

I've seen the same thing with someone else. They swapped cranks from early to late notches design and the engine started and ran ok. I wonder if the "CASE Learn" variable can account for the difference?

I know when we switched a 96 to a 97 we had to take the harness, computer, cluster, also had to change the coils backing plate (as in take the plate off one and switch the coils from the other coils around as the connectors on the older cavy didn't have the connectors. Forgot what the firing acronyms were. SFI and MFI or something? Been awhile sorry.
