    NW102mm TB on an LS3...what else in addition to ETC Area Scalar?

    I put my NW102mm TB on my 2010 Camaro SS, and changed my ETC Area Scalar from 5636 to 7380 based on my research here, http://www.hptuners.com/forum/showth...ht=Area+Scalar specifically post 15.

    My car idled great immediately, drives really nice still too, starts the same as it did with the stock TB.

    When I'm rolling and hold the clutch pedal down, the car returns to idle normally.

    When I'm rolling and put the shifter in neutral and let go of the clutch, the idle will climb and hunt...the moment I hit the clutch pedal, it returns to normal.

    I've set the coast down spark to be the same as the idle spark, and it helped some...but I don't understand what's causing it. I can get a log tomorrow if you guys want, I forgot my cable at home and won't be back there until then.

    Is there anything else you'd normally change for the TB? This was not an issue with the stock TB.

    I don't ever run that high of an ETC scalar with the 102.

    Uh.... Clutch out coast is screwy? Sounds like a small decrease in the BRAF tables should work. Or a small decrease in the Area Scalar. Can't remember if it's increase or decrease which divides the total BRAF numbers.....
