Any one know the trick for adjusting idle timing? I have managed to make it go from a stock 15 to 18 degrees to now a very lazy idling 5 degrees with just a 95mm zr1 throttle body change. I did change the value did all the math came up what I believe to be close enough on the max area like 6284. Guessing its something with the larger opening trying to keep the idle at the stock 585 rpm so more air and reducing timing I just don't know what to do other then raise the idle some. There is no timing tables for idle like the gen 4 stuff so guess you have to change up other tables to get the idle timing your looking for. I have a lazy throttle on free rev now and idles like it has a small cam with the low timing and smells dirty though its at 1.00 at idle. Guess its the timing making it stink now. Guessing guys tuning for cams had to figure this out so thanks in advance for any help.
Also if any tricks to help throttle response out of gear. Im sure just fixing this will help but also notice that when you rev its only commanding 40 percent throttle and no matter what I seem to try that is all it gives. It will rev its just lazy. My 07 Tahoe is snappy as hell for a fi vehicle with some timing and fuel adjustments. Its impressive for a stock cam 5.3 almost embarrassing to rev a gen v they are so lazy.
