Evening folks, first time using hp tuners and im sure your aware i have a lot to learn. a little back story, i used vcm scanner to see what a log file should look like and a professionally tuned car just for comparison. my buddy has an ls1 nova gasser that we test drove and logged (ill include his as a reference if needed). one thing i noticed with his log file is that hes getting getting ltft and stft readings and i am not, also my 02 sensor readings are incorrect and i am getting a p0200 immediately upon startup. i have 2 new o2 sensors on the way and the have checked my grounding and probed my injector wiring as well, i get 12.5v key on on the pink wires and complete connections (while moving the harness) on the switched grounds all the way back to the pcm. any help would be greatly appreciate. please not that the tune file is in its infancy and i haven't had a chance to get to base tune status because i want to get the fault code issue outta the way so please don't judge lol. Any pointers would be appreciated. engine is an lq4 6.0 with 799 heads pac 1218 springs and 42lb green top injectors (280-150-558) other than that its stock.
