Re: Why does HPP3 screw up the ecm? The problem occurs when the program is being loaded to your PCM and your connection is interrupted. Either by disconnecting the cable or by battery failure. Both instances can cause your PCM to lock and need re-flashing. Just make sure your battery is in good shape and don't mess with the cable wfile it's programming. Outside of those setbacks, I like the HPP3

Just make sure the other car is not running. Another option is to take a fully charged battery you have lying around, and jumper that to your cars battery (same thing, actually). That way, absolutely no worries on battery failure or low voltage. It's how I always do mine. Works great.
