Trans Tuning

So, is EFI live able to change the 3/4 shift points in tow haul? I have messed with the tables and axis points, and it will still shift from 3 to 4 at 55 mph without fail.

Any ideas or is that just the way it is?

Thanks!

Crickets. I assume that is just the way it is, the tables are basically for show, since changing them does nothing.

There's other parameters that must be changed in order for those tables to be able to function. There is a set boundary window for which each shift is allowed to occur within, move the 3-4 shift tables outside of the boundary window and it gets ignored and defaults to the boundary window.

Thanks Jim, so does the standard EFI software have access to those parameters or is it the user defined ones?

[Jim P]

User defined parameters is needed

Great, and you can't get them now right?
