Free LS1 Tuning Software (all you need is TunerPro)

[cobra30689]

Hi Guys, I have managed to the the Bin file from my PCM a OS 12212156 which came with the LS 6.0 Engine I got from a scrap yard.

I also got the .xdf file for the 2002 GM Vehicle in this thread.

The original transmission is showing as a 4L80E but I want to use my 700R4 as this has very recently been fully rebuilt.

The 6.0 LS will be going into my 1989 GMC Vandura G2500 Van.

Am I able to just change to transmission type and then save or is it more complicated? to I need to change other settings aswell.

I need to delete VATS
EGR
Cooling fans
Probably the Speedometer section with wheel size etc.
Maybe the 02 Sensors aswell. (still reading up on whats needed).

Many thanks.

Changing the transmission from a electronic to a non-electronic (or manual) trans is quite a bit more complicated....it's not as simple as *just* changing the transmission type, and there are some who say that isn't a good idea as other problems can arise. You'll have to dig through EVERY transmission DTC and turn it off.....otherwise the PCM will be looking for a TCM and start throwing codes. IMO it's easier to just reflash the PCM with a manual OS. In my case, I went on CarGurus, searched for a 4.8 pickup with a manual trans.....grabbed the VIN, went on GM's TIS website ($40 per VIN) and reflashed the PCM with my VXDIAG pass-thru. Of course you'll have to make the rest of your changes in your list.

Somebody else tried changing the trans type, flashed ot in using pcmhammer, and it bricked his PCM. Tried it on another and got the same result. So don't change that setting.

Hello i am New here and this is closest place i see to ask this, if i am wrong please let me know . I have a friend that has a 2000 k3500 7.4l fuel injected auto. Can this be tuned. I did put a new (used) knock module in it (Knock Codes). It did help some but motor is fresh with new heads and this thing is a dog he had a programmer on it but cant remember what it was and he sold it awhile back. Is this a em3494u pcm pcm # is 16208991, and what is needed if anything to flash back to stock or tune it please. Cant seem to find any info via google search. How can i read pcm like in ls droid or other free stuff i dont have HPTuners yet.

It will use the older "Black Box" Vortec PCM. At this time HP Tuners is your best option to tune this PCM. Many have upgraded from the Vortec PCM to the 0411 LS1 (P01) PCM. A Google search will point you in the right direction if you choose to do this upgrade.

Ok Next question this is a complete harness swap with 0411 pcm correct i think. Any sug. On donor vech for harness trk has 4l80e

thanks LRT for Blackbox info i found this just before your reply and also jr from driveway engineer also provided link

A 2000 model year 7.4L would have been paired with a 4L80 transmission, and would have used the older "Black Box" Vortec PCM. This was the final model year for the 7.4L, and they never used the later LS1 (P01) PCM - sometimes referred to as an 0411 PCM - so there is no OEM wiring harness available that had a P01 PCM.

This brings up a question re my 2000 Camaro PCM, which according to the hptuners scanner is a P01 (it says "ECM: 10, VPW - P01"). This is the original PCM that came with the car (which I bought new in 2000, so it's definitely original). But supposedly 2000's did not have the 0411 PCM, so wondering what I really have. I was considering getting a 0411 just for the supposedly faster cpu (compared to the 99-00 PCMs). It is running the correct OS for 2000 (9381344), which I plan to replace with an 02 OS (12212156).

Over two years ago, I posted a couple of XDF files for use with TunerPro editing software, specific to the LS1 type PCM. Below is a link to my original thread:

I am not going to revisit the comments made in the original thread, nor the number of times that “free” LS1 flashing software has failed to materialize. I am cautiously optimistic that this may finally be on the horizon. Please read the thread linked below:

http://www.gearhead-efi.com/Fuel-Inj...han-You-Think)

A hard working group of enthusiasts is attempting to bring a no cost LS1 Flash Tool into existence. Given this development, I went back to creating more XDF files for LS1 type PCMs. These XDFs are based on the original work of Dimented24x7, and the disassembly that he shared freely.

This disassembly allowed me to create a template for basic tuning (enough functions for an enthusiast to tune their own PCM). Each subsequent XDF was based on this template and disassembly - the same way that commercial tuning software companies would have developed their product.

The attached instructions (PDF) below have been updated from the 2016 version.

A new feature is the “Operating System” button, near the bottom of the Parameter Tree. This will show you the Operating System of the LS1 type PCM BIN file that you have opened. No matter which of the accompanying LS1 XDFs that you have currently selected for use with TunerPro, the Operating System will ALWAYS be correctly displayed - for all 512Kb and 1Mb LS1 type PCMs.

This feature will help ensure that you select the correct XDF for editing your BIN file. This is how commercial tuning software works. It determines the Operating System in use, and then automatically loads the corresponding editing file. You must load the corresponding XDF manually - but the concept is the same.

Please read the attached instructions. Then download both of the Checksum Plugins (512Kb and 1Mb), and place them into the TunerPro folder on your computer, as described in the instructions.

After this has been done, download the XDF files from the posts below.

*** Note: I will update posts #2, #3, and #4 below with new XDFs as these are developed. ***

Thx LRT, I've been able to read, edit, & save my bin after following these tips. Going to write now. Thx again.
