HyRev 7500 ECU box

......and while we're at it......why is it when you install the little "chip" voltage regulator in the instrument cluster it's considered an "upgrade" but when a similar transistor chip is used in a modern ignition ECU all of a sudden it's a fake piece of ****? I find that pretty interesting.
Rob no way for the heat to dissipate thats what kills them. If they mounted them to the top of the heat sink it would probably be fine.
