I have been fighting the dreaded hyperflash issue with my 08 Silverado forever with limited success and decided to look into having a custom bcm flash done by White Automotive. Along the way I discovered they no longer do this. It used to be you sent your bcm to them, they programmed it and returned it. You could do it with a used bcm off eBay but it was still a hassle. Now a company called www.btdieselworks.com does it via Autocal where they email the tune to you just like Blackbear does with a PCM/TCM tune. They offer several options like remote start run time, fogs with high beam, drl elimination, etc. I just ordered a bcm flash and will update after I receive it and install it. If you don’t have an Autocal they have other options where you rent the device to install the tune file.

After posting this I visited White Automotive and they now direct GMT900 owners to BT Diesel Works for programming. There’s also an option for a device called the AutoSync which does things BCM programming can’t but it can’t do some of the things that BCM programming does like the things I want.
