So here's an update. I disconnected the unit, reconnected, reinitialized, and recalibrated.

I am able to select the different modes, but only when engine is OFF. I cannot change modes when the engine is ON.

Second, there is absolutely no difference between any of the modes. White, Green, Blue vs Purple, Red. I tried each mode (turning my engine off each time) and drove around the same 3/4 mile (or so) circuit. Nothing was different than when the unit is not connected. Throttle response is identical in every instance.

Does this thing even work for anyone?

Ok, so I got cranky and busted out the multimeter. I had wired the reverse wire (safety) into fuse #5, back up light as mentioned in another thread (which I now cannot find).

Turns out fuse #1 (back up) and fuse #5 (back up light) are +12v all the time when the car is on. Not just when you're backing up.

So, the reverse safety was doing it's job perfectly -- the unit was disabled when I had the car on. I removed the reverse wire from fuse 5 and the unit functions. And now, I can DEFINITELY feel the difference between the modes.

My last quest is to find out why my back up fuses are always +12v even when I'm not in reverse.

I want to follow up and say that this product is definitely geared to the automatic transmission since you plant your foot down once and the throttle over time mappings can do their thing. None of those mappings (especially the ECOs) work right with a manual as every time you shift, it just kills the throttle input when you step back on the gas.

While this is obvious now that I have it, it wasn't obvious how those mappings worked when reading about it. Throttle over time mappings will work every time you press on the gas. With an auto, you do it once. With a manual, you're off and on it every gear. So, ECO mode 1, 2, 3 and BOOST mode 1, 2 are sort of pointless with manual.

I've found the most success with the throttle position remaps (green and red mode) since these don't have a time component, just a remap of the throttle positioning. Red makes the throttle a bit more twitchy, which can be fun. And green mellows out an otherwise heavy foot for smoother accelerations.

Honestly though, I cannot say it's worth the price for a manual transmission.

Cheers.
