I think he wants the spacer that goes behind the iac that can limit airflow across the IAC. You adjust 2 set screws.

Idle air adjustment plate. LMR sells them. I fell for the trap, now it’s sitting on my shelf in my garage. Didn’t work for me.

If your timing and TPS aren't properly adjusted and you don't read the instructions properly you may think it's garbage; worked great for me on a half-dozen of 11,12,13 sec n/a modded street cars and two 306 blower cars. Reduced or eliminated the Rolling idle.

The thick CLOUD of tire smoke ,the SMELL of burning rubber,and the CHEER of the crowd ....PRICELESS.

I already sold the OP mine that DID NOT work for my application. It did absolutely nothing for me. We re worked the tune and that fixed my issues. Maybe OP can share his experience with the one I sent him. Hopefully it worked for him.

timing is 10deg BTDC, nothing hard there

TPS is NOT adjustable, and is in spec between 0.65-1.15Volts

drag racing and rolling idle problems??.........MINT.

Wow what a reply; fyi I never said I had any Rolling idle problems and TPS is indeed adjustable once the factory holes are slotted and then readjusted to optimal .99V with KOEO, but I bet you have no idea what KOEO means right?

I guess that means your MISINFORMATION, makes your reply a richer reply!

truth dont care about your feelings

your post clearly states rolling idle issues.....but that is expected when you have no idea what you spewing about

Sorry to tell you, but he's right.

It's not adjustable. Or rather, not meant to be adjusted. When you turn the key, that voltage reading is basically just a check point. That's it. It renews every time you cycle the key. As long as the voltage reading is in between the low and high values, all is good in TPS land.

That .99 BS is all myth from back in the late 80's and early 90's before the EEC-IV had been broken down and reverse engineered. Now today, we know how it all works. And that's how it works. More or less.
