Customizing Canned Tunes.

[Power Hungry]

Please... fill in the personal and vehicle information so I can have some reference of who this is and what we're working on.

In regards to the shifting, please note that the Custom Option is labeled "SHIFT FIRMNESS", not Shift Pressure. There is a reason for this. This option does NOT change shift pressure, but instead changes the time delay between the offgoing clutch and the oncoming clutch and is calculated in percentage change from the current values. As for how much pressure is added to each shift, there is no flat value. Heavier throttle/higher speeds have more pressure than light throttle/low speed. If I had to give a ROUGH value, I'd say 5, 6, and 8 PSI for the 1-2, 2-3 and 3-4, respectively.

One thing to keep in mind is that all Custom Options make changes to the MODIFIED file values (ie. Level 1, 2 or 3), not the stock file values. In other words, if the 1-2 shift delay on Level 2, for example, is 450 milliseconds and you set the 1-2 Shift Firmness option to +5%, you end up with about 425 milliseconds delay. If you set it to -10, you get 495 milliseconds.

If you are running a valve body plate and need the shifting corrected, you'll need to have a file built to eliminate ALL shift pressure and delay modifications. There's really no other way around it.

As for the other custom issues, again I'll need to know what vehicle and calibration codes we are dealing with before I can look into it any further.

Take care.
