This is my tune with what I believe are the necessary mods to begin tuning when my o2 parts show up.

I notice after doing the last steps cutting and pasting the VE table, the table (B8101) looks pretty jacked up. Can someone peak at it before I plug it into the car?

Thanks guys. Sorry for a ll the newbie issues.

What size camshaft do you have in this motor?

The zones look odd to me but they may work just fine for your camshafts, the only way to know is to start it up with it. Post a log an easy way to clean up or smooth out the vve table is subtract or multiply a small percentage like .5% or so from the whole table and zone edge align too 10 gen coffs the gen vve and it will smooth it out.

you missed a step or two....

you need to paste a copy of your original VVE table over the one in this thread, then "generate co-efficients" and "generate VVE". Then save the tune again. the VVE shape you have here is what occurs after you alter the MAP and RPM boundaries and do not rebuild the VVE from the stock data.
