Hey guys,

I am trying to create a tune from a basetune from an australian Holden for an american 2005 GTO.

It has

- 102mm William TB and LSXR intake
- LS3 416 Stroker
- 11.8:1 compression
- 90mm Granatelli MAF
- 46lb inj @ 3 bar

I have a difficult time starting it without using my foot to crack the throttle. If i hold open the throttle about halfway she starts up fine. after 5-6 seconds giving throttle it will hold idle just fine. How would I go about fixing this?

Another issue I am having is light bucking at 1500-1800rpm at very light throttle cruising. Besides that area the car actually drives pretty nicely.

I will try and post up a few logs later and also my tune.

Any help would be greatly appreciated.

I have the ecu set in open loop now and she seems a little more driveable. I was wondering why table B0141 and B0142 have the axis Intake Valve Temp and ECT? All the values in the table says 1.46 as well. I looked at the other tables in the tutorial and they have map and rpm and AFR? Do I have to change the values on the table? How do I go about doing that?
