Can I replace a 939 ecu with a 563?

[MW562]

I have a 1992 940 turbo, and I’m like 95% sure that my ecu is dead. Car will not start, when it did run it had a weird stuttering issue, now the injectors do not fire at all. All grounds to ezk and ecu are good. My cps is working, my ezk is receiving signal from cps, and my ecu is receiving cps signal from ezk, but injectors are not pulsing.

Now, as far as I know, a 563 ecu is non egr, also an early year ecu. But will the car at least run with this ecu and with my ezk (214 gold box)?

I think it will run ok (both are turbo B230FT ecus), but the 563 doesn't have efan control, so you shouldn't run it very long.

Did you fry the injector driver in the 939 by running the wrong impedence injectors? The driver can be replaced

Injectors are stock, could this still be a possibility tho?
