Hello, am an old school type of guy that was convince LS is the way to go for relatively easy upgrades and parts are easy to find. Am overwhelmed with all the information on what should/should not be done when doing a swap, double edged sword with the internet LOL

Am currently trying to program a PCM for standalone. Am using TunerPro to make the updates to the bin I read from the PCM, but now can't get the updated bin (or any bin/data) to write to the PCM. It's out of a 2000 Silverado, the PCM OS # is 9373372 (512k bin). Am trying to use LS Droid Legacy to read/write, but since trying to write the updated bin am consistently getting errors during just the setup. Any help/suggestion will be appreciated.
