crx zc

Junior Member
i have swapped a zc into a crx i'm getting a code#43 from ecu. the ecu is from a 90 integra is is codeing because the ecu is for a b18??
 
Code 43 isn't valid for a PR4 90-91 Integra LS ECU.

Are you *sure* its 43? What is the pattern of the blinks?
 
the code is four long blinks and three short ones?? i have benn told it is a fuel system code and that would explain my sucky gas milage the ecu is from a rs integra 90
 
the sucky gas mileage is because you're using a PR4 to run a ZC. Not meant to happen.

The code 43 is rather mysterious. I'd try to find a civic/integra ECU
 
a 89 integra had the d16a1 right?? dohc code 43 is a fuel injector,fuel pressure,fuel pump,o2 sensor. isn't a civic ecu have diff air/fuel ratios,fuel pressure than the zc that i have it is a dohc one!
 
your using the wrong ecu, its a wonder that car will even start, use a crx or civic si ecu or an 88-89 ecu out of a teg,
