Free LS1 Tuning Software (all you need is TunerPro)

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.

Thank you Rick
I placed plugins(github) to tunerpro directory and duplicated to documents/tunerpro files/plugins
No result
There is only 2 plugins which present since installation. No new one
Is there any manual how to disable TB?

[yoheer]

And how to mod BIN for switching to manual transmission or th400?

Found Transmission type scalar and G1207 Vehicle platform options table in .xdf but it's written in comment that theese parameters should NOT be changed

[B52Bombardier1]

I predict a transmission "Segment Swap" for you from a similarly equipped 7603 OS. But I will also be the first to say I have never needed to do a segment swap for my PCM devices. Just lucky, I suppose.

Rick

[yoheer]

How to make segment swap? Do you mean just to copypast a part of raw data from one bin file to another? Using any HEX editor.
And i`m still confused how to make DBW to DBC mod

[B52Bombardier1]

See my advice in post # 138 above. Your PCM needs to be one of those hardware numbers to have the IAC hardware. If your PCM has the IAC hardware on the internal printed circuit board, simply bolt on a DBC throttle valve and I think . . . . it will simply work.

Others around here will correct me if I'm wrong but I just looked around the 7603 OS and it appears that IAC support is already there and running in the background as dead code if using a DBW setup.

Let's see what others have to say.

Tried to read 01 F-body pcm bin with hammer, using VCM2 via j2534. Failed.But test button says OK.

What about mongoose, mini vci els27?
Some other j2534?

[B52Bombardier1]

I use a Bluetooth OBDLink MX+ OBD2 module to read and write to my P01 and P59 PCM devices. Works great and I have a small, 3 amp bench power supply and a junk yard PCM wiring harness.

Rick

[yoheer]

Got mx+
I like it very much.
One question:
How to make pedal be linear with electronic throttle? Or even open the throttle wider with less accelerator pushing. Open faster and wider

[yoheer]

Everybody use 12587603 XDF with the same BIN operating system.
I tried to open 12585950 BIN and it works with that XDF perfect. It shows different parameters and tables and they seem to be correct
Now I do not understand anything. Why it is so?
As I understand, it should not work with other OS.

Hello, not sure if this is the best place to post this question but here goes.
I am going to be swapping a 2004 junkyard LM7 into a 1968 K20 GM truck. I'd like to enable analog AC request. As I understand it, only those PCM's with DBC IAC transistors in the PCM will have the circuitry to handle an analog AC request.

So I used PeteS's excellent LSDROID Ver. 0.2.2B and OBDX Pro VT bluetooth device to download my OS from the PCM. My original PCM is a Service No. 12586242 with OS ID 12606960. According to LT1SWAP.COM, my PCM does not have the circuitry for analog request but PCM's with Service No. 12576106 are among those that have the IAC hardware internally and which can handle analog AC request. So I went back to the junkyard and found one. Opened it up, and sure enough the IAC transistors are on the board.

So here's my question. Can I use TunerPro to enable the analog AC request? I am not finding that parameter anywhere so I'm guessing it's not been defined in the xdf. Speaking of which I am using "Operating System 12587603 - 1Mb PCM - 2004 model year.xdf". I do have a PCM with that OS so I tried that first and could not find the AC request parameter, so I don't think the issue is not matching the xdf with the OS. According to this post on PCMHacking,

https://pcmhacking.net/forums/viewto...=6734&start=10

the 12606960 OS in my original PCM is an exact match for the 12587603 from the IAC equiped PCM I found. So I'm hoping that an XDF mis-match is not the issue here. Sorry for such long post.

[Neukam]

The IAC drivers are for the Idle Air Control stepper motor used on drive by cable throttle bodies. All of the PCMs use the A/C request input to control the A/C relay output. Different calibrations handle A/C control differently depending on what sensors or switches were used on the vehicle. I am not aware of an XDF for 12606960, which replaced 12587603 as a service update. The PCM can be flashed back to 12587603, and I would recommend doing that as it is probably the best supported OS for the P59.
