I am new to this forum. I have a 1993 GMC K1500 with 5.7L TBI. I recently swapped out the 4l60e with an NV4500, which brought me to interest in tuning. With the current ECM, the truck idles high when I press the clutch and lacks power at highway speeds(There is almost no acceleration). I just purchased all my equipment to be able to data log and flash my own chips. My first data log using TunerPro RT I noticed my knock retard degrees were way high(at 24*+/- .3 constantly). Scrolling down the column, this is the only part I noticed the knock count to increase(screenshot below). What does this mean? Do I have a bad knock sensor?
