How to make a M6 w/230/228 cam idle?????
Well I'm not big into the edit stuff yet and have been studying the software some tonight and I am tuning a friends car also and I added 200 rpm to the table and it still doesn't want to idle. What can I do to change it? I HEARD that I can do something with the fuel and change it but what do I do to it? and which table to I do it in?

how's it not idling? just dying or is it bouncing around trying at idle (rpm) ?
On my car w/a 232/240 cam, I reduced the main VE table by a factor of 75% from 0-1200 RPM .. and it idles great
But I'm an auto ... so not sure if this is auto only...
Autotap the car and watch the IACs ... I'm guessing the problem is the idle hole in the TB isn't large enough for the new cam ... my car's idle hole is enlarged (but I forget what size... I just took a set of drill bits, found one that was the size of the stock hole and then drilled it out until the car idled ok ... make sure to do this OUT of the car though (remove TB))
you're prolly maxing out the IAC and can't get enough air to maintain the higher idle...

yeah you're gonna have to drill the TB a little to help out. It made a night and day difference between cold hard starts, warm restarts, waiting 60 seconds on a mid warm day, and not surging. I did 3/16" which was a random choice. The car locks up (a4 here) at 900-1000rpm in 4th gear and cruises along.
surging,driveline lash,etc is not good
