Im Trying to reflash via SPS but am learning that i cant due to it not changing the vin? How do i use this tool in conjunction to get the job done? or is that possible with this tool at all?
It's possible with the tool for most E38 ecm's.. I do know some of them refuse to change the vin for me with this tool until I perform a sps programming event.. Watching an sps event and you can see that's how they do it.. write Os, write calibrations, and then change the vin using the same procedure my software does..
One thing to try but I am not sure how to do it for people who pay by the vin.. When you start techline connect do not connect to the vehicle, click past that screen and start sps2.. type in the vin you want.. then year,make, and module if needed, then when you click next it will connect to the ecm and you'll get a popup stating vin mismatch.. There may be an override button you can click on that will attempt to program the E38 ecm and then after programming it will try to write the vin using the same method and steps as the little program I wrote..
If you want to try my software feel free to give it a try, pretty self explanatory on how it works, if you have a j2534 device to use with sps then it should work with my software as well.. Please give some feedback on it though if you do..
One thing to mention is that not all E38's are the same.. Depending on the year and the operating system you cannot hop back and forth, attached is a pdf explaining that for the e38 and a few other ecu's..
