It should be like all other preludes under the carpet at the front passenger feet may be behind a flat protector plate
the ecu should be under the carpet on the passenger side. unplug the old one and plug in the new!
Beside the ECU under the passender side carpet
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.
u cant... it runs the car...
The diagnostic is an LED on the ECU which is under the passenger side front carpet. there is a flap there, if you pull it down you will see the flashing code. You have to count the number of flashes. There could be multiple codes, so watch carefully and count one after the other.
Not without electrical work. The 1997+ Preludes have OBD2 wire harness while the 92-96 Have OBD1. Different wire harness/sensors/ecu.
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!
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.
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.
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.
