There was a gent on the forum (I believe) that would reprogram your pcm. Remove rear O2, egr , adjust speedo for gear ratio and tire size and trans line pressure. I for the life of me can't remember his name or find my paper work. I thought he was in like penn. or ohio somewhere it that neck of the woods. I need my line pressure turned back down so any help would be appreciated

There are alot of people on here including myself that do that.

There's a fair chance you can DIY, using PCM Hammer or LS Droid to read and write the PCM, and TunerPro to edit the .bin file.

Hello,

Yes, if it is a P01 or a P59 powertrain control module, you can certainly do it . . . and for zero cost. As NSFW mentions above, PCM Hammer / LS Droid and Tuner Pro RT can be your friends here - good You Tube videos as well for you to consider. I'm also starting to dabble around with another program called "Universal Patcher" that has allowed me to correct a BIN checksum that I bodged up and I've also done a segment swap with UP.

So I read and read on this downloaded the programs and I believe I'm looking at my bin file but I can not find the trans line pressure parameter. Is it called something funky??

Thanks

I'm looking at one that has a couple of tables called "Shift pressure," with columns for each shift (1-2, 2-3, 3-4).

Different XDFs use different terms though. Hopefully someone will eventually take it upon themselves to standardize them but for now, each XDF uses whatever terms the XDF creator preferred.

would I use the xdf that is in the tuner pro install or are there others available

Thanks

Others are available. Never edit a BIN OS number with a different XDF number. If you edit a BIN with a mismatched XDF definition file, it is certain that you will cause checksum problems and likely brick any PCM you write that BIN into - not good.

What is your PCM BIN operating system number?

Here is a snip of the OS

My bin and the xdf I used is 12202088 for 2001 512K

Thanks for the help

A very richly detailed and correct XDF file for that 12212156 OS exists. You should be able to find a listing for it around here on a github site.
