has any one ever heard of some kind of mod to the electronics in the pedal system it is said to increase response greatly?

 

I did that & it made a big difference. Now the truck is way easier to control at low RPM's. It's easy, try it.

 

how exactly do you do it and what is it called?

 

Try this,,,


Rick...

 

Look close at your go pedal, then follow the bar it is mounted to up, there is a IVS switch (idle validation switch) with 2 wires coming out of it above the "foot pad" . If you push down on the pedal just like your foot does when you drive, you can see a metal tab push against the plunger on that switch and it will click. Bend the metal tab on the pedal assembly until the click happens with the least amount of pedal travel. Make sure you don't go too far, the switch needs to click again just before the pedal is at rest.

Why, you ask?..

Look farther up the bar from the IVS and you will see a rheostat style switch with 3 wires coming out of it. This is the AP (accelerator pedal) sensor, it tells the computer how far the pedal is pushed down so the computer will do its thing and make the truck speed up or slow down. If the IVS clicks right away as you push the pedal then AP can send the computer a lower signal allowing you to control lower RPM's than you can if the IVS doesn't click right away. The computer don't look at the AP sensor until the IVS tells it the pedal is being pushed.

Try this.. Start your truck, push the go pedal until the engine revs up, now try to maintain the lowest RPM without going back to idle. You will see that there is a wide gap in RPM's from idle to what you can maintain. Now shut the truck off and bend that metal tab as I described and do the test again. If you did it right you will see you have control of lower RPM's than you had before.

Let me know how it works for you.

 

That way is more involved than what I did & I'm sure it would work, just takes a lot longer to do. I find it easier to bend the tab with a crescent wrench until the IVS clicks the soonest.

 

ok i did it but it doesnt seem like it did all that much is there any way to bypass the click because if you bend it past the the click(where it doesnt click when u hit the pedal) all you have to do it hit it one time and then its fine until you shut it off i think is there anything else i can do?

 

nice cheap mod. Thanx for the infp guys.

 

I'm sure no two trucks are the same. I couldn't maintain less than 1150 RPM with my truck, anything less and the IVS took over. Now I can maintain ~800 RPM without the IVS taking over. For me it was a good mod well worth every penny I spent on it.

Your results may vary.
