[QUOTE="CurtisF, post: 307254, member: 829"] I haven't datalogged my truck yet with the new changes, so I'm not entirely sure where the idle PW is actually ending up at. But as always I can set values how I want, and the truck does its own damn thing when it feels like it. That's the one thing I've noticed about the PW table. I can almost set whatever values I want, it doesn't care. I get more changes out of that table if I adjust the curve or slope of the fueling, how quickly it rises and falls... or doesn't. For example, my last two major tuning adjustments before starting this thread had two entirely different PW tables, but much of everything else was identical. In both cases, the PW at idle rested at around 1.45ms, even though the tables had completely different values. But the idle characteristics were both different, how they came off idle as well as how they came back to resting idle after driving. Also warm starts were affected, as a flatter PW table had a harder time settling into an idle after cranking. Currently the idle ICP is down below 450psi, down from my other files of close to 530psi. Base idle speed is up to 750 RPM's. Mine is also set to 1's across the board too ;) And I was having a bit of issue with ICP climbing rapidly as RPM's came off idle, but not coming on with the fueling. The result was a choppy feel at light throttle. So some of that has been pulled back a bit. Now I can watch my ICP gauge in the cab climb more with fueling rather than with RPM's. [/QUOTE]
