Just because the ecm will accept the voltage input doesn't mean it's correct. The optimal setting for the tps is .95-.99 of a volt. If it's reading to high or low, it changes other setting in the system to try and compensate for it. The manufacturers making the aftermarket tps's tolerances are not always what they should be. So instead of getting a new tps that reads the same, the adjustable piece on the t/b makes it easier to set w/o having to enlongate the mounting holes on the new tps.

I thought that was where you were going to go with the adjustable tps.

It turns out that the computer sets the base tps (idle), and sets WOT as 2.7v above that.
If the TPS idle is at .65v, then WOT will trigger at 3.35v.
If the TPS idle is at 1.10v, then WOT will trigger at 3.8v.

All other uses of the TPS signal are differential, or rate of change; not absolute.
For example the accelerator pump type function looks at the rate of change of the tps value, not what the tps values really are.

There is no benefit to setting the TPS to .95-.99v, as the computer will re-zero anything in the range of .6v to 1.2v.
Personally, I think my tps idle was .7 something on my last datalogs.
It makes no difference.

Here is a link that covers some of this stuff...
