Hello folks. I just bought a few days ago a 93 civic hatch with a d15b7 engine. I have a problem with getting the car out of park so i stick the key in the key hole to be able to move it. I was doin a little work on the car and notice it has a 92 prelude si h23 manual ecu. Can someone tell me what is the stock ecu for my car? Many thanks.

LOL so wouldnt the car never shift gears and run like poop?

 

The ,92-95 Civic platform uses a cable control for shift selection... there is little input from the ECU. What you need is a 37820-P06-A5X... X = 0, 1, 2 or 3. There is shift interlock communication inside this ECU that likely will cure your ability to shift from park normally instead of having to use the key manually in the over-ride slot in the console.

I cannot even imagine WHY there would be a 2.3L Prelude ECU in your car in the first place... that is the kind of thing that someone does just to get the car moved from a dangerous place to the safety of your own garage, not run it indefinitely.

 

The first 3 gears of the OBD1 automatics are mechanically controlled by the transmission itself. The ECU controls engagement of 4th (overdrive) gear and the torque converter lock.

Yes I would also expect that to run like crap due to the different cc size of the engine.

 

it runs. But i get very bad gas mileage , have the engine light on.

 

thanks alot! Will make sure to get one asap. I got the car like that. I dont know why they did it.

 

i see. So no 4th gear for me lol.
