I am trying to tune my transmission pressures to make my truck a little more friendly to drive normal but I'm having issues.. I am trying to lower the line pressure in the lower load ranges so the shifts are not so harsh and raise it up in the higher load areas so it shifts nice under load and doesnt burn up. I was trying to do it by just assuming that while under light load it should be making between 100-200 ft lbs. That didnt work so I logged a bunch of tranny pids including the GM.TRQENG pid and its all making sense why I cant tame down the shifts like I want to. This goofy thing thinks its making over 300 ftlbs at 22% throttle and around 2000 rpm....... Im thinking that is extremely inaccurate, My question is: what does it use to come up with those numbers?? I assume it uses a calculation from the amount of fuel being used (among other things obviously) and the fact that I am running it on e85 and my "flex fuel" sensor isnt working properly (at all) I am guessing it thinks this thing is a monster that makes stupid amounts of torque when really its just confused. I have not changed anything to tell it that it is not running straight gas as I dont think its necessary when the flex fuel sensor is functioning. (could be wrong but figure I will cross that bridge when we get there) Is this something that will sort itself out when I get the fuel sensor issues sorted out? any thoughts??
