The only difference I can think of is The J-spec ECU will not care if it's disconnected.
The A-spec ECU will throw a code if dosen't see the ACV solenoids.

Of course, he was the one that first mentioned the Cosmo AFM.
So this is "*** grano salis".

My ecu doesn't throw codes and none of my solenoids are connected. Unless there is a seperate test for emissions codes?(I used the 2 led system on the test plug)
I am S4 which doesn't care as much though. Don't know about S5 ECU's.
I passed with my S5 Jspec ACV on the dyno smog test. Although I did gut the ACV diaphram
Airpump,cat,and ACV constantly pumping to cat == VERY low emissions

Whether you'll pass emissions with one is anyone's guess. I'd say it probably wouldn't make that much difference, but it depends on the test procedure.
What makes you think the J-spec ECU won't throw an error code?

The series four ECU does not have a code for Split Air Solenoid. The author of the thread has a series five.
If you have a S4 with a JSPEC ACV you'll pass emission. The lack of a Split Air Solenoid has squat to do with passing emissions. As long as the rest of the ACV is functional and the airpump is working AND the catalytic converter is good, there is no problem. The air pump goes to the exaust ports area of the engine where it counts.
IF you have a S5 with a JSPEC acv, and the emissions checking station checks for codes, maybe you can take the split air solenoid off the old acv and connect it to the harness and tie it out of the way/sight so it does not throw a code.

So??? You know Jack about S5 emissions OR you don't know Jack about S5 emissions? You say you know Jack, but Jack is a friend of mine and he says he does not know YOU. humor
