Ok i just have a quick question, im wondering if i splice the MS injector wires into my stock ECU injector harness, wont there be a conflict with the ECU wanting to control the injectors and the MS wanting to control them as well?? If someone could please explain this to me it would be greatly appreciated. Thanks

Why would they still be hooked to the ECU?

Your injector harness has a quick disconnect that seperates it from the main engine harness. I went to the junkyard and pulled one of these connectors and then wired the MS to it. That way I can switch between the MS and stock ecu. You wouldn't want both to be sending voltage a the same time. It would be one or the other.

ok well wat i guess im asking is, i have a pigtail that is run right to the MS right now and i want to make it so that CEL number is gone for not having the stock ECU injector harness hoooked up, so wat your saying is i cant just hook up the stock ECU injector harness and then just splice the MS wires into each injector

No.

ok? so then what can i go, just while its being inspected plug the stock harness in and then when the inspections done switch to the MS?

Yes.

Yes. But make sure to drive it enough to clear all the stored codes if your state checks for such things. There are certain driving/load conditions the stock ECU needs to see to clear codes that might prevent the ECU from showing a ready state.

don't forget to swap the injectors back to stock also.

is it safe to drive it with the stock ECU controlling fuel?? and i dont have the stock injectors in there i have a 2G stock turbos injectors 450's i believe, will that be a problem

On a related note, I know of one case where someone hooked up an extra four non-functional injectors to the stock ECU while controlling the functional injectors with the aftermarket computer. He kept the 4 extra injectors underneath his seat - He just had to deal with the injector ticking!

I wonder how the ECU checks that the injectors are plugged in anyway, anybody know?

Still throws a code.

Why is that sir???

well djtrickee, i talked to DarkOne and he told me to hook up the stock injectors to the stock injector harness and zip tie em together and let em chill in the engine bay, that way the ECU still recognizes the stock injectors are there, he said he did it and it worked

Do whatever you want.
No one here said it wouldnt work. No one here also said you won't blow up your car, which I could see happening.
Expect the stock ECU to throw multiple codes when dealing with the megasquirt install.

I know for a fact that it didn't work on mine, nor did it work on Star Turbo Talons(terry) and several others as well.

ok well first off i have been running MS for about a year and a half now and the only codes ive thrown are the EGR which has nothing to do with MS and the 4 CEL's for the injectors. The car has been running great and it hasnt come close to blowing up, and im just trying to make it inspection ready so i can sell it

Can someone tell me why the ms cant simulate a code to make the ecu thinks its controling the injectors. The AEM unit has a feature like this and it works on the v6 avengers and others. Maybe im asking on the wrong forum.

Because its not written into the MS code. That would be illegal.....

Just about any car with OBDII using m/s is illegal. So whats the big deal long as the car has all the proper smog features or meets the regulations for emissions?
