06 400EX

I just installed the Air Cooled Sensor (Trailtech) I don't have a clue what these motor temps get up to. But watching the Vapor computer. The temp sitting at idle climbed to 280!!! (Farenheit) I think it would have went higher but I turned it off. Most cars would melt down at those temps. Has anybody ever measured the engine temp?


Thanks for any info.
