It will be in an unlocked state and allow uploading a flash kernel into the ram. If the flash chips file is only slightly damaged the PCM will boot and start sending either an OS or calibration recovery mode message and will allow you to reflash until the next time its turned off so there is no requirement here on how precise the timing needs to be. You may only have a 1- 2 second window where the the PCM will be flash-able but that depends on how bad its damaged. Depending on what tool your using to flash with you may need to click start a split second before you release the pin from ground to get the timing on this right. 5-1 seconds and IMMEDIATELY attempt to re-flash the PCM. With the PCM turned ON ground this pin for.

View or download the picture and you will see there is a pin I've highlighted. So don't change that setting.With out knowing more about how you flashed the file I'm not going to say this will 100% work but it's very unlikely either of the PCM's are actually bricked unless you altered something in the boot sector of the bin file. Tried it on another and got the same result. Somebody else tried changing the trans type, flashed ot in using pcmhammer, and it bricked his PCM.

I'm not sure on things like the COS1 but for any of the COS's that have extended boost tables you need to do a complete OS flash every time you make a change in any of the settings as tables have been moved outside of the 'OEM' calibration data range and none of the free tools avaible would correctly flash the calibration data range for a COS. Since COS's from tools like HPT and EFI Live do not contain any type of calibration data you would need to find one that's been setup already(and is compatible with the XDF) as there could be settings the COS needs filled in that would not be in the XDF if you tried to populate the raw COS yourself. They will not work with a stock BIN file.

will need a matching COS to use one of those XDF's.

Do I need a bin or just take a stock bin of same OS as xdf and when tuner pro saves it, it becomes a COS? If anyone has a custom OS for speed density on a P01 ECU with a usable XDF, that would be amazing as well! Thanks guys

I seen he had XDF for two custom operating systems in that post but no BIN files. I am trying to run my 2000 5.3L in speed density and been running into a road block. So I have a question about COS he mentioned in the post below. Of course you'll have to make the rest of your changes in your list.

In my case, I went on CarGurus, searched for a 4.8 pickup with a manual abbed the VIN, went on GM's TIS website ($40 per VIN) and reflashed the PCM with my VXDIAG pass-thru. IMO it's easier to just reflash the PCM with a manual OS. 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. Many thanks.Changing the transmission from a electronic to a non-electronic (or manual) trans is quite a bit more '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. Probably the Speedometer section with wheel size etc. The 6.0 LS will be going into my 1989 GMC Vandura G2500 Van.Īm I able to just change to transmission type and then save or is it more complicated? to I need to change other settings aswell. The original transmission is showing as a 4L80E but I want to use my 700R4 as this has very recently been fully rebuilt.

xdf file for the 2002 GM Vehicle in this thread. 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.
