I have a Honda 90EF with a b20 vtec engine swap with, what i assume to be a B16 Head. I have come to the conclusion that my ECU has gone out. Seeing as how i bought the car with the swap i have no idea what parts or components they put in the car. Because i know that the ECU that my car has now is chipped and modded and what not. So i was wondering if i could just get a stock ECU of the same ecu, that it has right now, and use that to move the car because im moving houses in a couple of days and i really would prefer to take my car with me haha
Thnaks for any input.

 

The ecu that came with your car is modified. Therefore another SAME stock ecu won't work for you. Your only option is to get the same ecu, socket it and wire it for vtec. Then install your custom chip again.

 

And how would I go about doing that?

 

Start by posting the ECU currently installed in the car.

Next post the diagnostics that led you to conclude that the ECU is bad.

 

Sorry I took so long to reply. I've been busy with work and finals sorry school. But I believe that I have a chipped P28 ECU for a B20Vtec. The reason I believe it's the ECU is because I do not have a spark in the spark plugs and I have exhausted all other options that I know that would cause this problem. I've replaced the wires and the distributor. So if anyone has other options I'm open to them.

 

Do you have a check engine light on? maybe a code 15?

 

I believed the ECU was chipped to have the check engine light off. But if it wasn't was is a code 15?

 

If you have a P28, you have some sort of obd1 conversion.

You should probably take some pictures and start compiling some data on what you actually have in your possession so you can figure out what you need to do to get it started.

Since you changed your distributor, what model distributor did you take out, and what did you replace it with?

It's fairly uncommon for a whole distributor to be bad, and usually the failing part IN the distributor can be replaced and remedy the situation.

 

code 15 usually hints to check the ignitor. if you are running with most codes disabled in the ecu program, aka troubleshooting mode that needs to be fixed...

 

I replaced the distributor because i had already changed all the parts in the distributor. And i put one in from a b16 since the engine was built with a b16 head that was the same kind as the one it had on already. Since there was no spark i jumped to the conclusion that it was the distributor. Is there anything else it could be other than the ignitor?

 

Wiring or ecu....but if the ecu won't display code because it's in debug mode its hard to troubleshoot...

 

Sorry what would be my suggested course of action?

 

I would try and borrow a gsr ecu, if it runs, that tells u a lot.

Hard to say without knowing more history.

 

If it doesnt run, u have wiring gremlins. Good luck.

 

Well it hasn't had much history. The only thing that strikes me as strange is right before it stopped working it was on for quite a while. I moved it and turned it off and after it didn't want to start. That and I now suspect that the fuel pump isn't turning on.

 

You can hear the fuel pump. Turn the key to the "on" position, pump should come on and run for 2 seconds and then turn off.

 

maybe the main relay is bad

 

I've gotten several different ones, and I can safely say it's no that
