Re: Coupe 5MT swap questions

chipped ecus are obd1 ecus that can have a special chip installed into the board. You can write things to this chip like engine basemaps and delete sensors. Also you can do what I did if you do find one with a key. You can basically pull out the transponder reader. cut the wires, lengthen them away from the cylinder. Tape the key for the ecu to the transponder reader and use your key as normal. If you try to keep the transponder where it is the keys will interfere with eachother and you wont be able to start the car. Also if you cant figure out how to wire up a clutch switch you'll have to cut the ignition wires, solder them together and put them on a toggle switch like I did. If you dont the car will start with the wires crossed but the starter will run continuously until it burns out. Roughly 2 trips 15 mins each. The switch lets you turn the starter on and off. If you use a manual ECU youll need to ground the clutch psw or it wont start.

The other key wont work with your cylinder and the dealer might not make you a key for the ECU because they'll want the VIN number off the other car. I have an f20b in my accord and the only way I can make it run is with a chipped obd1 p28 ecu because the F20bs had immobilizers and are obd2 so theres no way around that afaik. I also think they started the transponder thing in 98.
