Pony, the connector would have to be unplugged to connect your programmer.
I just drove about 60 miles and did some more testing.
The performance mode is cool. You select performance, and the screen prompts you that you must be at zero mph. Then once you take off, the display reverses color to let you know its recording. When done you check the statistics page and it gives 1/4 mi, 1/8 mi, and 0-60 times.
I also set the shift point and watched the 2 leds come on at the set level. There was a small glitch which needs to be addressed, but for the most part this gauge is awesome.
I am on my way outside to get some pics.
