    School me on transients!

    Hello all! Ive been reading up some on transient fueling, as that's the next step for my truck. I have the maf and pe dialed in, but now Im looking at transients. My wb bounces alot anytime the throttle changes. I understand what transients do and mean. But i dont understand quite how to log them and recognize what changes need to be made when I do recognize a transient dip or spike. I dont have the EIO, so I cant datalog my wideband. I'm gonna go ahead and attach my tune for any critiques.

    I've been trying to figure a systematic way of doing it but so far I've been pissing in the wind. I have got it to richen up but I cant figure out what does what. Gas impact factor is what I used to richen it up but just the last 5 columns of IVT. If you do the whole table my truck won't start, too rich. I'm up to about 2 times the stock value. By the way I'm am scaled using the half injector and 2X stoich so my truck will be way different then yours.

    Any help will be appreciated.
