Hi,

I just purchased a manual '92 hatchback civic. Problem is, it had check engine light on, but the guy told me it didn't matter because everything was working correctly. I bought it, and shortly after I managed to pull the CEL code out of the ECU.

I checked on the ECU thread and I received code 19 which is "Automatic transmission lockup control valve". I was shocked since I own a manual car. I shortly discovered after that the guy put a automatic ECU in a manual car.

So my question is, what happens if I leave the ECU as is, in the car? Do you recommend me to buy another one or reprogram the current one ? What's your opinion on this?

Thanks for your help greatly appreciated :-)

just get a manual ecu off ebay or someone on here

 

There is nothing wrong with having an automatic ECU. You may throw a few automatic CEL's, but that's it, nothing that will adversely affect your performance.

exactly. Only problem might be with smog tests, if applicable

yeah nothing wrong with it depending on the motor you have as well you might have a shorter cut off on the auto ecu ....

 

it really doesnt hurt anything but if really want i'd suggest getting it reprogrammed

 

Just convert the auto to a 5 speed ecu. There is a write up. And i belive is in the FAQ section.

 

Thanks a lot guys for all your replies. I will leave it as it is right now, I have other more important things to invest my money on for the moment on my car, if I want to go through the winter!

Thanks again!

Cut jump RP18 and add a jumper across RP17. Thats whats converts the ECU from Auto-Manual.

 

Hey thanks for this insight!

Very interesting :-)

 

Agreed, I bought a 92 SI that had an EX auto ECU in it and threw the same code. I did the auto to 5 speed conversion to the ecu myself and fixed it. hope that helps.
