Icon5 Can I use the same ECU?

Can I keep the auto ECU and not throw a CEL with my 5 speed swap? It is an H22A W/JDM Auto P13

Thanks for the help.

Re: Can I use the same ECU?

Re: Can I use the same ECU?

You could also use a P28. Yeah, I wouldn't try to use the Auto P13.

Re: Can I use the same ECU?

You can disable the auto... I believe if you don't all it will do is throw a code. My p13 that came with my h22a 5 speed swap was an auto; it worked just fine.

...this is an auto, right? thus the "AT" vs "MT" on my p14 and p28...


point: you should be able to use it, at most someone who knows how has to disable the auto.

Re: Can I use the same ECU?

I dont care if it throws a code as it already does because its a 4 plug ecu as long as it doesnt throw the CEl also, I guess I will try it out soon enough and see what happens.

Oh ok, well then I dont know if I want to disable it or sell it on ebay and buy a manual one. I guess its just a resistor that needs to be de-soldered and placed elsewhere on the board.

Re: Can I use the same ECU?

don't fell like you have to get a p72... it has a knock sensor and IAB control, but it's not right for the h22 anyway... a p06/05 converted or a p28 will do you just as good for cheaper (and if you really want knock sensor of IAB I know eCtune supports them, don't know if hondata added those options yet).
good luck!

Re: Can I use the same ECU?

So the 5 speed swap is complete, wierd thing tho, I used the P13 ECU for the auto just for the halibut and it didnt throw a CEL. Vtec kicks in just fine.
