ok..once again, JDM d15b in a 89 crx hf, im running a jdm p08 ecu, got all of this from HMO (ecu and d15b)

my o2 sensor is NOT hooked up, BUT the check engine light IS OFF?

why is that?

when i turn the ignition to the acc position, all the lights in the dash come on and go off, just like they are supposed to, even the CEL, but when i start the car the cel goes away and dosent come back on?

im not complaining, but im just wondering why it does that?

 

its non obd and i dont believe it runs a diagnostic on the 02 readings....

 

Ed Zachary, you wont throw one.

 

actually his car is converted to obd1 and im guessing its because there are two wires you have to jump for the light to come on
