jcasper i to had some timing rattle on 5 & 7, but alot of that was due to my larger injectors so i now run 6 & 8 with no timing rattle whatsoever (quiet as a stocker). power seems to be just as good with maybe a hint more of smoke than the timing sw#'s. just give the even #'s a try you'll like it.
I will try level 6 next time I get a chance. I need to get rid of the rattle.
I tried level 6 today.
Level 6 SUCKS. Sorry for being straight and to the point, but that was my first thought.
The rattle is gone, but there is NO power. It feels good to about 1,500 and then it's flat and nothing. In 6th gear at 65MPH I put my foot to the floor and the speedometer and tach hardly moved.
My Smarty is sitting by my LazBoy and I'm going to download something off the Mads site to try for tomorrow. The Beta is just way too rattly for me and the no timing level 6 had NO power.
If it wasn't for the rattle I would continue to run this. Level 5 seemed almost perfect except for the rattle above 2,500RPM.
I don't want to sound like I am accusing or anything, but does every SW get dynoed before you release it Bob? Then again every truck is different and maybe it's just my truck.
I am not trying to be an *****hole or anything here but this is a "BETA" software. I don't think Bob needs me to come to his defense but it was given out on a "ask for basis" for all of us privileged enough to get it to try out and give feedback on. It was designated to be what all of us have come to consider as a standard. Don't you have larger than stock injectors? It has already been previously determined that larger injectors require a reduced timing program from the satndard in order to limit the timing rattle that you are complaining about. If you have a dislike or concern about this software then please give all of us your feedback and go back to what has been working for you.
I happen to find that this perticular version is probably the best all-around performer that I have tried. It is not too aggressive with the throttle response and it pulls nice and even from right off idle all the way to the top with reduced smoke from other versions that I have tried.
