    You have something funky going on with your tune. In the last log it shows you at 180* with a commanded AFR of 12.53, but the tune shows you should be at 14.62. Duh. I have enclosed a new tune for you. I have adjusted the commanded AFR and hopefully this will help. Let me know what you come up with.

    That fixed it Chad!

    It is VERY funky... but it appears that changing over the whole commanded AFR table to 14.63 and moving the PEvsRPM table to 12.x has fixed the issue.

    I'll get out here in a bit and do some driving on it to make sure it is working 100% proper, but so far it does appear to be fine.

    Thanks guys!

    Well I got bored today and decided to start playing with the TP-VE table as well. I started plotting out the data a little bit. It sure is a PITA to get all those areas plotted. I turned off all the throttle cracker/follower, dfco, trims, etc and got a fairly smooth graphing for the main areas of the table.



    I guess i'm gonna try and get a bit more of it plotted before I decide to enable any of it... and then I guess i'll just have to actually figure out what to do with it all from there

    Looks like mine does, except nicer at the bottom, probably due to you turning dfco off. What you can do to if you are itching to test it is to tidy up the points you are missing and enable the table, but disable on say 3600rpm or where-ever your table runs out. Basically that will run it up to 3600rpm. Thats what I did. Worked well for a quick test. (maybe put some high values outside of this point as a failsafe)

    What are your impressions Richard, can you notice any difference in driving?

    Cheers,

    Performance seems to be more directly related to throttle action. (surprise surprise) With MAP B3647 table it was good, but seemed to follow behind throttle a little. All in all makes things nicely responsive. Ive not done enough extended testing to see what happens to fuel economy. From my wider reading it appears it may suffer a little. But I think for circuit racing situations, drifting etc, it would be excellent.

    well i've gotten my TPS VE table dialed in to within +/-2% between 0-3000rpm & 0-20% TPS.

    My setup is in my sig, and with the largeish cam I've always had some driveability issues, and most of them appear to have already been addressed by enabling the new table.

    My cam has low vacuum at idle, at idle i've always jumped around between 4 cells 70-75kpa/800-1200rpm tables. With the A/C on, the idle has been fairly rough, even with different timing settings at idle. Now it only has to jump between 2 cells and made the idle MUCH smoother.

    I've also always had some issues under some cruising conditions. Lots of studdering around 1700-1800 rpm, and again up at around 2000-2100 rpm. Once again, the new table has seemed to taken care of most of those problems.

    Taking off from an idle, and transitioning between the shifts has also smoothed out. Throttle response is also slightly better.


    Just from my impressions with it, I don't know how well the table would work being fully populated and enabled throughout the entire range (not to mention it would be a MAJOR job to populate and fine tune, especially without the aide of a mustang dyno), but it seems to work excellently for the lower regions.

    Good news Kris, I think you have pretty much highlighted exactly what this O.S is good for and a great combo to prove it on.
    Your comment "but it seems to work excellently for the lower regions.", I would also suggest that everyone just use the TPS VE in the area's you cannot get consistent MAP values in then switch back to the MAP VE once things become steady as you have done, good stuff.

    I was wondering the same thing... but when looking a little more into it, I found that 3647 is in the Holden OSv5, but not in the F-Body OSv5... even though it was in OSv3
