I'm a little unfamiliar with the process. If I'm tuned on an aftermarket EMS. Can I just plug the oem ecu back in, disconnect the SC belt, put some miles on and get inspected?

 

I don't think so. My guess would be that, all of the tables of the factory ECU are different than your tune. Both turbos and SC run rich to prevent detonation if you went back to a factory settings on your set up you could be putting your engine at risk.

 

I'm a complete noob, but I thought there was a way to disconnect a pulley that disengages the blower?

Otherwise I'll need a shop that can help out with inspection.

 

What state do you live in PA or NJ?

 

There may be I don't have any experience with removing belts so I can't give you any advise. However, do you have a catalytic converter? Check engine light? Just because your car has a supercharger doesn’t mean it will fail inspection. If the inspection station can’t hook up the car to an OBD reader, which happens with older model cars is, the station will stick a reader in your exhaust pipe and measure emissions, if you are in the normal range then you should pass emissions. As for an aftermarket ECU, that I am not sure about, usually the ECU is linked to the VIN of your car, being that yours is after market, but will show as OBDII compatible am not I am not sure what the station would do. I would assume it’s similar to what they do when you have an ECU replaced, but what that is I don’t know. I would post something in the Under the Hood forum one of those guys may be able to help you out.

 

Nj

 

Both haltech and AEM render the obdii useless. Can't read from it

Also with. Bigger injectors and fuel pump. I'm sure even with a cat id fail

 

Thats what I am trying to say, you do not need an OBDII in order to pass inspection. NJ has 2 ways of testing emissions a sniffer test which is a tube placed in the exhaust and an OBDII. The thought behind OBDII is that if there are no error codes then your emissions are fine. However if you have a vechile w/o OBDI or II then then they revert back to the sniffer.

Even with bigger injectors it would still be possible to pass emissions, there are a lot of variables depending on how the car is tuned, but if the cat can handle the extra CO load then you will be fine. How to determine that I don't know.

edit - I got bored and did some digging at lunch. And you may have been right, with a vehicle which is equipped with OBDII but is inactivated then it looks like you may fail NJ inspection. However if the car has bigger injectors you will need to change them back to factory before you put the ecu back in. If you are in/near SJ There is a performance shop that may have a way around your problem. if you are intersted.

 

My car only has 20k miles. I'm going to be running an SOS sc kit with a high psi pulley I'm hoping for 400+whp

 

Sorry I meant MPG. Modified my previous post might be worth a reread. If you want the shops number let me know.
