I installed the 180* T-stat 2 days after getting my SRT8 and over the past 4k miles everything has been great. Yesterday it was 62* outside and raining ... the "coldest" that it has been here since I got the car. Had to run to Best Buy to pick up Bioshock so I started the car, backed outta the garage and made my way down the street ... a few miles into the trip my CEL came on. Swung my the dealer since its right down the street and they pulled the coolant temp code (which apparently throws some others regarding temps) since the coolant didnt heat up fast enough. Aside from sitting in the garage and letting the car warm up or driving hard at the beginning of the trip (the rain prevented that), do you think/know if the Diablo will alter that coolant "warm up timer" so the CEL doesnt get triggered like that?
