Need to replace ECU in '94 Accord EX, VTEC, 4 Dr. A/T. Have # from old unit 37820-POA-A51 and have found identical used unit for sale. To install used unit (or new, for that matter) is there any "flashing", "reprogramming", etc. that must be done prior to installation, or do I just install and go? Any help greatly appreciated. Wife's car and have to get it going! Thanks!

 

Pull out the old one, plug in the new one! Easy peasy!

 

Hey Chrisnick...thanks for the fast reply! Sounds simple enough! Take care!

 

Ok, will do that tomorrow. Thanks! Front mount being the one next to the exhaust manifold/bottom middle of radiator right?

Yeop. Honda calls it a 'stopper' it is really a limiter not a mount per se. If you have excessive movement or vibration at idle, check the firewall mount. On AT cars it is vacuum controlled hydro mount. When idling in gear it will allow a larger chamber of hydraulic fluid in the mount to open, allowing the engine to 'float' and not transfer vibrations to the car. When throttle is opened the vacuum controls seal off part of the chamber to stiffen the mount.

Verify the mounts vacuum controls are properly working.
Verify the diaphragm on the mount is not ruptured,
Verify the lever on the mount is not seized.
Verify functionality of the mount and note if there is any difference when the lever is moved.
