Default TPS setting

Quick question, as I'm out playing with my car.

I can' set the TPS.

In log #4, min=30, max=202.

When I go into 'special' edit. I set the min TPS to .6 where it was .7 in the dashboard. No problems.

On the other hand, there is no inbetween for max of 3.9 (202/51). If I set it to 3.9, I get 102 in the dashboard. If I set it to 4.0, I get 98.

What gives?

How significant is it if I have to go with 98 as my TPS?

I hope you get an answer here. I want to do the same thing today. Sounds like an easy way to go 4% faster, but that sounds too good to be true.

The throttle position should be at 100% on the dashboard when floored. Turn the car off, ignition on, go into the Dashboard and if when the peddle is fully depressed it should read 100%. If not, play with the numbers to get it as close as possible.

I have the same problem. When I floor it the dashboard shows 100, but when datalogging the TPS value doesn't go above 98. Changing the value to 3.9 gives me TPS values of 102. Unfortunately you can't enter a value of 3.9_.

Chris,

There must be an easy fix for this. As soon as the TXS guys see this post, they'll walk us through it.

I have a feeling that the fix is in 'user' constants and setting the boost control solenoid...that AND stuff; as opposed to in the 'special' constants.

I just did it by typing in a value of 3.95 and got 100%

I think you guys are stressing over this a bit too much. Get it close, and call it a day. If it's just a few percentage points above or below it makes no real difference.

By the way you are calibrating how the UTEC reads the sensor, not how it meters fuel, or how far the throttle plate actually opens.
