Ok so I live in one of those lovely places that plugs your car up to a computer and does an emission test. I'm looking to build up my car but need it to pass emissions and am wondering is keeping the stock ecu the only I'll pass or is there a way to do a stand alone EMS that can piggy back the stock ecu keeping it able to pass. I searched for threads on this but didnt see to much on what I'm looking for

Thanks guys.

 

hks fcon pro maintains the obd II port

you can only be tuned by an authorized hks dealer though

 

unless youre gonna be making 650 whp then you probably dont need a standalone. what are your plans for the car?

 

but i understand that the stock ecu is only good to 550 whp??

 

so care to explain this?

What do they look for when they plug into the ECU? Here in Ohio they plug in on OBDII cars to see if there are any CELs that aren't showing up on the dash...

 

all the tuners i call...AMS, TTP, BR...say they'll only tune the ECU to 550 tops

 

Maybe you should call Mellon?

I think his personal car is something like 630-700whp?

 

We would not tell you the ECU has a whp limit.

We just tuned two stock motors last week to 563whp and 602whp on stock ECU.

The stock ECU is limitless.

 

Damn I guess I didn't get this memo...

How many miles do you drive your car per year? I know in PA you can be exempt from emissions if you put on less than like 2,000 miles per year.

 

Here in TX all they look for is no fault codes. Apparently they check emissions on older cars, but that doesn't apply to me, even though I'm sure I'd fail.

 

here in illinois it they plug their **** into ur OBDII to see if ur pulling any codes...
