I just put a JDM B18C1 in my 93 civic, I'm running the p28 ecu from the D16Z6. I was told that on factory settings it is robbing my B18 of horsepower. I just bought my first honda like 4 months ago and never read much into them before. I dunno if should ship it, if I do which one, or if theres a way to program the ecu myself without a chip. any suggestions?
 
I wouldnt even run your car with that ecu, its probably robbing your engine for alot of fuel! Get a p72 that is obd1 and call it good.
 
Do you have any check engine lights? If so find out what they are and take care of them, that will probably fix your problem. If you havent all ready add any wires for vtec and the secondary butterflies that you may need.
 
Ok I got it all hooked up and working but when I drive it at first it runs fine. Then it throws a check engine light and the engine wont pull at all. And I cant find anyone with an OBD1 reader. Any idea what the check engine light might be?
 
did you run all your wiring correctly? like knock sensor, vtec wires, o2 wires etc..? i have a 93 civic cx hatchback and i just swapped a b18c1 into my car using the p72 ecu and it runs perfect. You can check the code for the check engine light like normal. Just find the plug under the glove box and plug a wire to it and turn the key on to see how many times the check engine light blinks and it will throw the code.

Yup, this is the only way you are going to be able to find out what code you are throwing. Search on here or get a repair manual to find out how many blinks = what code. Good luck.
