Beside the ECU under the passender side carpet
the ecu should be under the carpet on the passenger side or possibly unde the dash in the center. unplug the old one and plug in the new!
u cant... it runs the car...
When a check engine light appears on a 1992 Honda Prelude dashboard it means the ECU is get an abnormal reading on one of the automobiles functions. Use a diagnostic tool to flash the ECU and find the problems associated the car. The flash will also turn off the check engine light.
It should be like all other preludes under the carpet at the front passenger feet may be behind a flat protector plate
Not without electrical work. The 1997+ Preludes have OBD2 wire harness while the 92-96 Have OBD1. Different wire harness/sensors/ecu.
I assume by the question that you have a bad ECU, and want to replace it with a used one from the junkyard. I, myself, managed to take an ECU out of a 1995 Honda Prelude S and it runs without a problem in my 1991 Accord. The 1990 to 1993 Accords share the same motor as the 1995 Honda Prelude S, so the computers are interchangeable. Also, you might want to check what engine you have. If you have the F22A6, then the computers are NOT interchangeable.
ecu program for 89 prelude si.what is it andwhere . htanks
Passenger side pull up the carpet remove the kick plate and it should be right under there. DISCONNECT THE BATTERY BEFORE YOU DO ANYTHING TO THE ECU.
It senses engine knock and sends the information to the ecu, which will react to protect your engine from being damaged.
The answer is no. The fuel-injected engine from your 1987 Accord is a direct-fit into a 1985-1987 Prelude Si, but will not fit into a 1988 or newer Prelude due to a completely different engine and transmission being used. The wiring harnesses and ECU will also be very different.
will a h23a vtech work in a 92 prelude? what extra will be needed or changed besides a chipped p28 ecu ..? I have a 92' Honda prelude s.i. with a h23a1 non vtech and im going to swap, but i need answers before i buy this engine..
