Only about .4 sec per lap of drop off from the front of the run to the end of it. Fast laps were in the 8.6 second range. Ending laps were mostly in the 9.0 range. I was thrilled with the speed and performance of the car. But I'm worried about the temperature that I was seeing on the speedo. Coming off the track, the motor was a nice comfy 132 degrees. But the speedo was way up there at 220 degrees. It didn't thermal or shut down. But that high of a speedo temp does seem excessive. Any thoughts as to why? or tips on how to get the speedo temp down without giving away any of the great power? Here's the readings from the LCD program card.....

considering these settings, why was my speedo coming off the track at 220 degrees and yet the motor temp was good? how hot is too hot for the speedo? what can I change to bring the speedo temp down? any help will be greatly appreciated. I love the speed and the feel of this speedo, and the motor seemed to like it too. But I'm worried about so much speedo temperature. Help please.
