Need help with my tune please Hi Guys
I have been having issues with tuning my camaro with LS6 engine. It has got a cam (not sure about the specs as bought the car built by previous owner). It has the following:
stock heads
FAST 92mm Intake manifold
FAST 92mm Throttle Body
long tube headers
upgraded with LS3/LS7 Card Style MAF
4" intake tube.
Wideband fixed on Driver Side Header
I have recently bought the hptuners two weeks ago as I am fed up with tuners doing crapy jobs. Basically, I am new to tuning and stuff, but I have gained some knowledge from watching videos on Youtube.
I know for sure the tune is not right as the engine dies/stalls when coming to a stop sign especially with AC running. Sometimes just revving the engine, the idle dips below the desired rpm and dies. Also, noticed the IAC count is two low.
Tried to increase my base running airflow but without any luck.
I am attaching my log file (engine running at idle) and the data file hoping somebody to help me out sorting the tuning issues.
Will appreciate your support guys.

Look under Spark---Idle advance---In park and in drive. You have very little spark in the in drive table from 0 rpm to 1200 rpm and down to .40gsec. Make that whole square 18 on both charts(drive and park ) until you get it sorted out. Then go back and make it look like the stock chart except with higher numbers. Let me look some more.
