Working on tune for 4.8l that has Truck Norris NSR CAM installed. This truck does not have a traction control button and seems like the transmission is limited in first gear. I have adjusted the abuse mode in every direction and all engine torque is maxed for testing / tune but no matter what I throw at it I cannot get the rear wheel to break traction from 0 speed WOT. I am not looking for the final tune to burn the tires up but I feel I am missing power in 1st gear. After 1st gear has transitioned to 2nd gear all seems great.
I have searched and combed through the threads and tried stock abuse mode settings and everything that seems to have helped others. Am I just fighting a lost battle from the 4.8L and stock converter? I am used to working with the 6L trans and 5.3 -6.X mainly, with exception of a 2010 crew cab with 4.8 and 4L I do not recall having this problem with 1st gear. GEN4 and few GEN5
On another note if someone could point me in the direction of shift pattern types would be awesome. I have no issues taking classes or books etc on them I just would like to understand what they do to the transmission and how the TCM activates them inside and outside of tow/haul / sports modes etc. I seem to think this is the BCM that is calling the pattern selection. This would probably need to be asked in a separate thread but could my problem be just simple shift pattern selection type that is stated "it is recommended not to change these values"?
Thanks in advance I am in early stages of HP tuners and tuning in general and I am not looking for a quick fix I really want to understand all the ins and outs.
