AIV delete/PRVR delete

[73EB]

Any of you guys doing these with stock ECU's on a N/A? I noticed in ROBO's article he mentions after chipping the ECU you can leave the AIV harness plug hanging. don't know if i'm reading to much into this but.......

Here's the paragraph he quotes it in. Thanks

"All the aftermarket ECU (Electronic Control Unit) chips of which I am aware delete the AIV function. I have a Jim Wolf Technologies ECU chip, so the AIV's in my car were just taking up space and weight. After I installed my chip, I disconnected the and removed the AIV solenoid under the hood, and cut the vacuum lines from the solenoid at the right and left fenderwells leading to the AIV's. The AIV vacuum lines are T'd into I drove around like this for a couple of years before I finally got around to removing the AIV's units themselves, when I had the car on jack stands for some other reason."

The stock ECU actually adds fuel to compensate for AIV. Some have deleted it with no side effects, some have had issues fouling plugs. Also, I have an early JWT ECU for my NA (pre-conversion) and it had the code to support AIV. I confirmed the ECU number with JWT. They also confirmed it has been eliminated on newer versions. So, not all aftermarket ECU's eliminated it...
