Hey guy's need some direction done the search thing but not what i was looking for . Proportional Gain vs Rpm vs Map is what i was looking for anybody no of any other sites on this topic for some good reading . I figured this is the table i'am looking for to calm down my Map from being so jumpy .

In the Tuning Guide Sticky, Chapter 5, '8063/'8746/'7747 section, Fueling. Explains how this works along with the purpose.

Well i have been reading and reading and to me it seems to be more geared towards the o2 proportional gain . I was looking for the Proportional Gain vs Rpm vs Map table. Some area's in my data log the Map is very stable and in others it is very jumpy maybe this is normal or maybe it is telling me some else is out of adjustment ? I just stated getting alittle more indepth so it takes abit for it to sink in and understand . Here is an attachment of my table .

That table is for the fueling proportional gain.

A jumpy MAP value can be caused by a number of things. From mechanical issues to tuning issues. Usually there are filters for the MAP that can vary according to some other parameter. Such as a transient MAP duration for less filtering.

Yep more reading and seaching , i'am offically lost LOL Thanks

Okay how about this if i post a mild data log would you look at it , maybe what i'am trying to do is okay i don't no as i have nothing to compare it to . Also if their is some thing wrong or out of whack i wouldn't no so a second opinion would be nice . I have been using DataMaster for the log.
