Free LS1 Tuning Software (all you need is TunerPro)

[sturgillbd]

I have a couple of questions regarding this xdf and the one for the 512k pcms. I noticed when viewing the VE table using this xdf file in Tuner Pro, The VE numbers range from around 1 to a little over 2. When I open the same bin file using EFI Live, There are normal VE numbers as in VE %. The conversion is approximately 48.212 * the number reported in TunerPro. I also get an out of range value when I set VATS to be disabled in Tuner Pro and open the bin in EFILive. I have an 03 GMC Sierra with a 4.8 with 4L60E. I segment swapped a 04 4.8 engine cal into an 04 5.3 bin from the same type truck and programmed a second PCM. I used EFILive to get the 03 calibration parameters such as MAF calibration and the injector data and pasted that data into the 12587603 flashed PCM. It runs fine but just playing around I noticed these differences. I am attaching screenshots of the things I see.

Maybe LRT will see this post. If anyone else knows, please chime in.

Thanks,
Brian

Thank you for the explanation. I had read the comments and the text is almost identical to what EFILive and even had the same formulas. I did a base install of EFILive just to compare the calibrations. I didn't set any preferences on how to display the VE. There is a learning curve coming from OBD1 and flashing chips to working with the LS calibrations. I apologize for any inconvenience

hi guys
1. trying to add plugins to tunerpro. Doing all by instruction. wanna add 512 and 1mb checksum plugins. they doesn't appear in help->plugins. what i'm doing wrong?
2. I have one pcm 12583659 (serv.#12586243) It is from 2005 car. It seem that I can use 12587603.xdf and 2004 bin files for it. Right?
3. What xdf should I use with 2007 4.8 engine? I'll specify PCM# a lil bit later
4. Is it possible to change operating system?

Hello,

1 - I placed my checksum plugins inside the C:\Program Files (x86)\Tuner Pro RT folder. Seems to work, no problems.

2 - If your PCM's have the green / blue connectors and a 1 megabyte memory capacity, they should work.

3 - The XDF file MUST ALWAYS MATCH the operating system, NOT the model year or engine size.

4 - Most of the time, you are changing the operating system. Completely overwriting your previous OS. This is because most of us are not lucky enough to have a vehicle with an original OS that has a supporting XDF file. We most always abandon our original OS and put in an OS that has good XDF support. The 12587603 OS is such a thing.

If I have 1mbyte pcm with green/blue socken and any part number then I can use 2004 OS 12587603. Right?
And the same stuff with 512k pcms?
One more question:
Is it possible to disable electronic Throttle body? Install oldschool cable-type TB and tune the pcm?

[B52Bombardier1]

You can only support drive-by-cable throttling with the following PCM's. They made P59's (1 megabyte devices) with the IAC hardware (drive by cable) up to 2007. But only in hardware (not service) numbers: 12575502, 12570558, 12583659, and 12589161. Any other 1 megabyte PCM won't do it.

Same advice applies in the red/blue P01 PCM devices. You must use mated and matched XDF files with your OS.
