    Im 100% sure its the ecu, as i have it wired to relay and i can physicaly hear it click then 1-2 seconds later watch the scan tool change temps. I havent had the time to fool with cos5 yet so i dont know how its gonna work. Im in the process of getting my iats down from the 230* range

    I know this is an old thread but i dont really hang out here much, however i have specific experience doing this.
    I have a 4.8/t56 turbo combo with cos5 and a msd 2 step. i connected the msd ground activation with the nitrous ground activation and ran it through the clutch switch. i set the nitrous activation to pull timing and add fuel and activate a few hundred rpm before the msd 2 step. it all works pretty well but its sensitive to the correct amount of fuel added to really have a good bang out the exhaust.
