i am able to scan 06 gto, 05-07 c6 without any issue but when i scan my friends 08 c6z, there is no data for KR, MAF (hz), INJ DUTY (%), INJ B1, INJ B2, OSB1S1 & OSB2S1, FAN%, Delivered Engine Torque, TQ mgt advance that i am used to getting. when i exported the data to excel, there is still no data there. rest of data like iat, ect....are fine. any idea what is going on? is there a different config file that i need to run for 08 C6Z? also when i exported it out to excel, under vehicle type, it says unknow. yes i did clear the last vehicle data before scanning. thanks in advance.
