Need to return my tranny line pressure to stock once I get the shift kit installed this weekend. Does anyone know what tables and parameters the Magnuson Superchips tune modifies from stock? Are all the modified values in the Base Shift Pressure vs. Torque vs. Gear tables?

i could email you the stock .bin file from my wife's 03 av

i could email you the stock .bin file from my wife's 03 av
That would be very cool, thanks. I'll PM you my email addy.

Anyone else with insight please reply....I still need to know which tables need to be modified.

Here's what I've got (thanks mucho ZDEN for the stock file)....wondering if there are any other tables I need to be concerned with....also wondering if I should return exactly to stock, or something different:

wow, those are some low force motor current values, it must have felt pretty firm.

check out the upshift pressure modifiers to, more than likey they are not changed though.

also you should return to stock, with mechanical pressure changes that come with the shift kit, you shouldent need to raise them anymore with the software.

I'm curious, how much difference did the shifts feel after you got the Magnuson tune? I'm trying to find some good setup tables for my truck to replace it with. So far the one's I've used haven't worked to well for me.

i have a bin file from my '03 silvy with the shift tables set up from the pred i had before i got hpt. i liked the way it shifted with these settings so i kept them. i even used almost the same settings for my '05

sweet i just hit my 100th post and it only took a little over 2 years!!

The 1-2 shift lurches under low-to-medium throttle....can't say that I like that very much. Other than that it seems pretty good.

Any chance you could email me it? :)

Good to know, thanks. :)

Found some interesting differences between the stock '04 Avalanche tune and the stock '03 Avalanche tune in Performance (Tow/Haul) mode. Wonder why they're different? :confused:

those values look fine the shift time table is part of torqmanagment I leave some in on normal and 0 it out on performance
As far as the 1 to 2 I finally found a way to fix it dont adjust the force motor table instead there is a modifier table 1-2 upshift you will notice some negative and positive values referenced to temp play around with it add -1 across the board and see how you like it. Also the base shift pressure table you can 0 out the first couple columns that will help
On the force motor table nothing wrong with going down just dont go up. Ive messed with the last column being 0 or max value Iv found it grabs the gear better wot with it set at a max value both are supposed to be full bleed off.
Check out jimmy blues tunes that he's posted on horist his shit is extreme but works really well and will give you a base to go off Ive had good luck playing with his ls1 stuff and he really really knows his shit.

Look at your Max Line Pressure under shift properties stock is 90. You were showing 96 in some of your tables. Most people on hptuners board say thats way to much. The shorter the shift time is the more firm the shift feels. Higher base shift pressures and short shift times give you a hard shift.

I have a shift kit with servo and run a slightly higher shift pressure and short shift times and have had no problems in 12K miles. I have stock max line pressure and force motor current.

honestly when the tc locks is almost a subjective matter it depends on what rpms you want to operate in. Even with the big cam I have it pulls more with it locked even under 2000 rpms low tps
this will take tinkering to get a feel for it Im still messing with it periodically
