TRex Idle Tuning On A4
Can someone tell me what I need to change in order to get my TRex that I will be installing to idle without fouling out the plugs. I am new to hptuners and I would appreciate any help I can get.

You don't really need to change anything for it to idle correctly as mine fired up perfect and find the idle almost instantly with the stock tune. I drove it for a week or so like that with no problems other than surging at low rpm's. Now with your Automatic the surging will be amplified as I could downshift or press the clutch in to keep it from surging until I got it tuned correctly on my wideband. The problem you will have is getting rid of the cam surge on an Automatic @ Low RPM's.

You got it to run on a stock tune, I bet that was a ROUGH idle. Ive heard of alot of people fouling out plugs extreemly fast with that cam. Do you run this car as your daily driver?

It runs pretty decent on a stock tune with an M6. It does lope a bit more aggressive with the stock tune as the IAC tables and Idle RPM are set pretty low for the stock cam. I bumped my idle up to 900 RPM and increased the IAC tables just to make it easier to drive in traffic. As far as driving it I probably drive in some of the worst traffic anywhere. It takes me up to 1 hour 45 minutes to go 35 miles to work down 85. I live up in Duluth and drive down near the airport everyday. It is like a parking lot most of the time. I drove it to work like this for about a week until I got my wideband so I could start adjusting things.

MN6 and autos are TOTALLY different worlds when it comes to big cams and tunes. it isnt even close bro. a Trex cam could possibly idle on a stock tune with a 6 speed since there is no load. but with the auto, you cant just stab the clutch and rev it and slip the disc
