1227303 ECU - problem with memcal

Postby autominus » Mon Oct 08, 2018 9:24 pm

I have a Passport Optima fitted with 1,6 litre 8V (C16NZ) engine, automatic transmission and a Delco ECU. This car is similar to Pontiac Lemans/Opel Kadett E. This car was importet to Europe form Canada.
This system is a classic Multec - GM TBI 700 and 0,8bar fuel pressure with the following sensors: MAP, coolant temp, TPS, inductive camshaft rotation sensor, oxygen sensor, IAC, injector.

I have a problem with the stepper motor control because if I use orginal memcal, stepper motor work only one way. When I use another memcal, stepper motor working good. But I can't drive, because I have another memcal only to manual gearbox.


I made copies orginal memcal, but I do not know whether it contains errors.

Thank you in advance for your help
