open the tune you want to write, then connect to the pcm-aldl and do a write entire.

I'll give it a try, thanks
Tried the write entire option and no matter what I did it would only default to write calibration. Every thing seem to work properly but the process only took less that 2 minutes. When I read the Entire ECM it took close to 15 minutes. Perhaps I have a computer issue but it work well with my other stuff. It's an Acer note book. I did read and write in the lower speed mode. I received no error message and don't have a clue where my problem is. Thanks for any help
Did you try it on the truck or just assume it isn't right?
Mine writes faster than reads.

I tried it on the truck many times, I get a trouble code 268a . injector flow not programed. I was told I need a tech 2 to copy the flow rates from the glow plug module . I thought if you write the entire ECM it would also copy the injector flow rates. Also after you start the write entire process, the screen still says write calibration. Should . I cleared the codes before the process but the light remains on. The vehicle starts and runs but the check engine lite stays lite and the remote start doesn't function. If I put my original ECM back all is back to normal. I bought the ECM pre programed with my Vin #, I also bought a used one from an 2009. The used one doesn't allow the truck to start and the vats relearn will not work. I also get a a code for security on the dash information panel. Any help will be greatly appreciated. I checked the both files with a Hex editor and the replacement ECM is missing code at several addresses. The files don't compare, which leads me to believe I'm not doing a complete write entire.
The company I bought the ECM from said it isn't locked or I wouldn'r be able to even write the calibration.
