ZR1 ECM help
I have a 1990 ZR1 with a bad ECM, had shop send it out and 7 weeks later said it couldn't be rebuilt. Shop cant find another one. Car has only 23K original miles and I just had all new injectors and coils put in car when the ECM went bad. If shop cant find a used working or rebuilt 1990 ECM, what are my options??
Has anyone done an upgraded computer in a 1990-1995 ZR1 ?
