Enable your idle switch and simulate it from throttle position is needed. Have you calibrated your LC1 recently? Also, your load scale in direct access is 114%! If you're running a 2.0 engine this should be at 100%

Where the hell is your fuel tab in ecu config?? wtf
 
I will try that tomorrow , Lc1 was calibrated awhile ago then removed until i finished my build couple days ago ,i will recalibrate it tomorrow ..Load scale in direct access was at 114% before i started , and reading in the 1g v3 dsml link no maf sd tuning pdf , it says Load scale tab: Leave alone unless a stroker motor. It should read 114.8 for all 2.0L cars

Fuel tab went mia , had to reinstall ecmlink and it came back (in log #2)

That guide was written a long time ago back when an older firmware release incorrectly calculated load for speed density. ECMTuning realized the mistake and released the next firmware with a 114% loadscale, so that there wouldn't be problems with user's current tune on the different firmware. Basically, if you tuned everything on the erroneous firmware version and then upgraded to the newer one, you should keep it at 114%, assuming you want to keep your old tune...

However, the default value is 100% for all 2.0L motors. And since you're having issues with your tune, you should reset it back to 100%. Make sure you're running the latest firmware as well.
