New Haltech ECU for Bumblestook

A few months ago I noticed that I could no longer connect my old laptop to my Haltech ECU. It wouldn't detect it and later it would actually shut my laptop off if I did. I setup a new laptop to see if the laptop was the issue but it gave a warning that whatever was plugged into the USB port was drawing too much power. I knew at this point the USB port on my Haltech Pro Plug-in must've shorted out since changing the cable didn't fix it either.

I ordered a new Haltech Pro Plugin for the S2000 which looks pretty cool with the new black and yellow color scheme to match the car. The guts and the firmware haven't really changed since years ago so it was as simple was swapping everything over, reloading my tune and configuration and firing the car up. I did recalibrate the TPS voltage which has changed a bit over time just to make sure everything was good and everything ran just fine.
