Free LS1 Tuning Software (all you need is TunerPro)

[S.O.B.B.]

Did anyone ever have any luck burning/reading/flashing the chips from ls pcm using tuner pro xdf/adx files.I'm asking because I didn't see a cheap cable for doing this.picked up a 0411pcm os12201281dbc for $20 from 2001 Tahoe.if it's as simple as obd1 with burning chips I plan to make a harness.have a method for 1x cam signal.possibly use BBC 24x crank ring and adapt it to my front balancer. be nice to be able to use this pcm for any engine.any advice appreciated. Thanks

Yes, and that's what this thread is about. :)

I've flashed my C5 about 20 times now with PCM Hammer, and I have a couple of PCMs on my desk that have been flashed at least as many times. I don't advise anyone to use it on their daily driver just yet, but we're getting there.

Thanks.I guess I should have been a little more specific.if I remove the chip and use an adp-019 (psop44 to dip32) to read it in my GQ4x4.then use the tunerpro xdf to make changes and reflash the chip and reinstall in pcm via surface mount zif.I ask this because I have most of this stuff already. I Do not own a cable to flash or read pcm through obd2 port.I do have a maxidiag obd2 reader that gives me o2 sensors.short and long fuel trims.iac.tps.etc so I can read live data.just want to be sure the files will work the same by reading/editing bin from the chip burner.I have a couple xdfs and looked them over.I don't have one for os 12201281which is what's on the service label.am I out of luck if I can't get that xdf.haven't seen one in searching.easy enough to go get another pcm with more supported os.lots at the yard I use.appreciate the help.

To use the bin file pulled from the lifted chip you will have to byte swap the file. Swap odd and even bytes. Some chip programmers have that built in.
You will have to byte swap the bin file before opening with tunerpro and byte swap again after you save it with tunerpro.

I can only recommend chip lifting for recovering bricked pcm. An OBDLink cable is not that much and will serve you well for other pcms too. Changing to xdf supported OS is a breeze with it. And caldata write takes less than a minute.

Thanks for that info.didn't know that the cable was not so expensive. But searched and found that the gq4x4 does have byte swap.I may try it this way just to see how difficult the soldering is.but thanks for your time.

I picked up my obdlink SX cable for $20 off Amazon. Why mess with soldering over a $20 cable.

Can you share an unlocked version of 12587603 1mb xdf.


I am doing a disassembly of that OS and it may help me to label known stuff faster.
It will really speed up the process.

Thanks
