Hi guys,
I got a stock file for a GMC Yukon Denali 6.2 by a guy here and everything seems pretty good, i have ignition, fuel pressure and disabled the VATS.
When I pilot injectors myself by sending a constant + and -, engine is starting and "running".
How can i fix it in HPtuners ? i attach my tuning file 2008GMCYukonDenali62LblackStock.hpt
Thanks !
