I know this is in another thread but I would like to get a definite answer as to what the line pressure adjustment is for. My very good friend Butch was over today to help me install my newly purchased DiabloSport tuner today. I have a 2007 and this option is not on Butch's 2006 with the 07update?
First off does anyone really know what this adjustment does? Will it firm up the shifts if you increase the pressure? Just seemed like there was no definitive answer in the other thread. I don't want to mess with it if it is going to wreck something.

 

There IS NO line pressure...ONLY rpm shift adjustments. 2 different things.

Line pressure firms up shifts
RPM raise/lower, just does that. No added or decrease in firmness or softness of the shift.

 

We get that the rpm adjustment raises and lowers the shift points, what we are wondering about is the option that says "Pressure Calibration" and then you click on that and there are 2 options: "Front LP Threshhold" and "Rear LP Threshold"

What does adjusting this do?

On my 06 the adjustment is in PSI and it says its at 112 then you hit the sideways button to the left or right and it goes down to 50, then you can only adjust from 0-50?

On Bighorn777's the scale was different it was like 250 or something like the earlier post.

What is the deal with this adjustment. On my tuner it is under the "engine" parameters not the "transmission" parameters. I am going to post on the DS forum too. Thanks
