Can I swap ECU's?

[SNOOZE]

yup its SNOOZE again with another n00b question....

Say i had 2 CB7s with swaped H22s.....but one didnt have an ECU, would i be able to use the ECU from the other car?

[BLUBB2]

Wouldnt recommend it but itll run it.Probably run like doo doo. Dont even start it until you get the correct ECU...P13..

That completely made no sense. Why would he have the incorrect ECU for the other H22? Unless he didn't know what he was buying.

A P13 is a P13. Make sure you disconnect the battery for about 5-15 minutes to allow the ECU to reset itself. You should be good. Or goto a junkyard and buy a P13 if you really need both cars running. They're not that expensive.

lol My bad, I misread the post, I thought he was asking what ECU would run it other than the correct ECU.

Are you talking about the turbo engine you have? If so, no stock ECU will be safe running that.

[iwork4mycb7]

if both ecus are p13/p28 chipped for the h22 yes you can

Its an engine with headers, and full exshaust system, thats it, ill probly throw the 550 injectors on it and thats it.....

[SOHC-FTW]

You don't need 550cc injectors on a bolt on car bud.Way to much for that set up.

for sure... need to clean the injectors, whats a good thing to spray them with?

[SOHC-FTW]

Break cleaner or carb cleaner make sure you dont spray anything but the screens heavily it can break down the orings.Not that it will as long as you wipe em down quickly main thing to clean is the screens though.

[deevergote]

550cc injectors won't run with a stock ECU. The motor will run terribly, and you may risk damage.

And you only have one header, unless you roll aroud with a spare in your trunk.


It's best if you explain EXACTLY what your setup is when asking a question like this, especially if you have more than one car. The answer you get might be the wrong one because someone didn't have all the facts.

Well I will be putting my turbo ecu on a stock engine with just dc headers and full exshaust system, my buddy said the injectors were dirty and needed cleaning so thats why I was going to use my 550cc injectors since imma be running my turbo ecu...this is all temporary until I get another ecu, I should be fine right, as long as I dont step on it too much, just wanna cruise it mainly....

You'll be lucky if it starts, Don't run a turbo ecu on a stock engine.
1) It will wash the bores.
2) It will give shitty gas mileage
3) You'll be lucky if it even idles.
4) It will foul the plugs.
5) It will kill the O2 sensor.

The list goes on.
