Hi guys ive mounted my L8 ecu in the glove box of my rally car and noticed when the door is closed after about 15 mins driving the rev counter and stuff starts going irrattic and also the fuel pump relay starts staying on and wont prime etc etc but I diagnosed this to the heat in glove box with the fuel pump relays and ecu in there with the glove box lid closed..

Ive since took the glove box lid off and left it open and now all seems well but the ecu still gets warm..

Do the ecu's get warm ive never noticed before see, also what can I add to help cool it any ideas ???

cheers Guys
