07 Envoy 4.2 tried to write the bin and it failed. I think I bricked it now lol. I'll add the bin file I used hp tuners to turn off security and converted the file to bin, it's been working on the P10 ecms just fine. I did read the file from pcm hammer as well before I tried to write the vats delete...

Thank you sir very much for clarifying that. Anybody have or know were to get a P08 bin, looked at gearhead, couldn't seem to find any. -Enjoy I have these in .hpt format 97-01 idk how to make them into a bin file though. Also have the P11 ecms as .hpt so if anyone knows how to convert these files ...

Any one have the flash chip number so I can look it up ? Trying to find the ground pin if anyone knows where that is either.

I tune these all with hp tuners I have some v6 97 ones sitting here and newer. I’ve figured out the ground pin on the 97 ecm so I can write my os on them with hp tuners. If you need anyone to help test your version out let me know. I also do the p11 ecms.

It worked I read a 02 Silverado P01 and doing a P59 right now. It’s slow about a hour to read os 12597120. I can upload the bin file just don’t know how to make the xdf file for it. And I can’t figure out universal patch for the life of me. Download ls droid for my laptop I guess this one don’t work...

I got it to work don’t know what I did but it’s reading the emc. Now to figure out tuner pro lol.

when it says its unsupported its talking to the obdlink ok, and will work. if the blutooth is disconnected and brought back up and you dont get that warning when you initialize then its on the wrong port. if its talking to the obdlink the problem is car / bench side. ignition not on or another elec...

I know the Bluetooth works had it working with forscan i can't get it to work with tunerpro either
