    How do you like the Super Chiller? I was thinking about getting one instead of a HX.

    Also, do you notice an increase in blower whine with your setup at cruis and light acceleration?
    Super chiller is great but, you have to get your tuner to get the ecu to stop adding timing. When the chiller is on the ecu will think it can add as much as 20* of timing. Once tuned correctly it works great.

    Blower whine is in line with increased blower RPM. Nothing crazy but is a bit louder when you stomp on it.

    I would expect the whine to increase under hard acceleration, but what about at cruise and LIGHT accel? Is there an increase under those conditions?

    What was happening when the ECU was adding the timing for the colder/denser air?

    Yes the IAT, stayed at 90 to 100* so the ecu got real happy with timing.

    Did it start to detonate?

    Re: A6 coupe put down 620 RWH

    So why did he pull timing?

    He didn't pull timing, he stopped the computer from advancing timing on it's own. The computer was adding 4-6* past what he set it to with the colder IAT temps.

    Re: A6 coupe put down 620 RWH

    I'm just wondering why he did he did that if that if there was no detonation?

    Because there would be detonation due to the ecu adding too much timing at wot.

    You may want to quantify that...

    On the dyno the car on a mid throttle pull would add timing and work great. 3/4 throttle the timing was getting into the 19* range which on pump gas was more than he wanted to see.

    I'm guessing this is just part of the conservative tune then?

    Yes
    I wanted fast but safe. All my GM cars in the past always seemed to get faster at about 5000 miles. Due to not being a daily driver it takes me awhile to get that many. I still have less than 3000 on the car but plan on driving it more as the weather has started to get nice.
