X Axis recalibration for TPS %

I see that most of the tables for the Trans upshift speed and down shift speed end at 57% Is it ok the use the axis Xref window to make the 0 to 100% tps? will this affect anything else or are those tables only ment to go to 57%
Thanks

Anybody??

try it and see... I remember changing a few things around... didn't do any harm

% is a poor way to express TPS on a ford, since they rely on counts.

Understood, so how would this system work? How many counts is 0% and how many counts is 100% TPS?

Thanks

The ford software displays the digital conversion of the 0-5volt scale the tps sensor uses. These units are called A/D counts or analog to digital counts. 1 volt is equal to 205 A/D counts. So your scale is 0 A/D to 1024 A/D. Please note that this is the absolute scale of the tps sensor and that the EEC uses relative tps position for most calculations. Relative tps counts is calculated as actual A/D counts minus closed throttle A/D counts if I recall correctly.

The best way to do things is forget about percent and just log the A/D counts.

yeah this was a topic of great debate when we developed the definitions. In the end more tuners said they wanted % instead of AD counts because they were tired of constantly converting 5V to 1023 counts etc. :shrug:

So back to my first post. why does the table on this particular vehicle stop at 57% ? Not to mention that some of the trans shift tables have the same value on the last two lines? I am just curious. I don't like changing values that I am not a 100% percent sure how they affect the outcome

So is TPS true TPS.
