How does this E85 Timing Map look?

I usually seem to see negative numbers or a zero in your ones. Other than it, it looks really good. E85 maps on a stock turbo (and even stock appearing for the most part) look very similar generally unless the car has a noisy motor and you havent turned the knock control down to make it less sensitive.

This is from a local tuner not on the boards...Car has a BBK Full turbo at 30 psi spike, kelford IX 272's, all other bolts ons. I know the injector scaling is way off but how does this timing map look? Ill find out later tonight what load Im spiking to and holding. Also, it seems that most people run a 12.0 AFR on E85. Is that what most are still doing?
Thanks

A few things I might possibly change with that map if I was to run it in my car is the timing in the 140 to 220 loadsYou can probably eek a little bit more out of it than that, as my map has about 2-4 degrees more, and doesn't knock. I do have my knock sensitivity changed a tad since I am on a built no balance shafts motor. Changing/tuning in that area will give the car a better feel when you are half on the gas, and "quickly" putzing around town. I would get rid of the non-linearity in the 100 load, from 3000 to 6000 rpm, but that just me being a little picky. One more being picky is you could combine the 10,20 & 30 load columns as you don't need that much resolution at idle & just above idle conditions, especially because the three columns are the same. Me personally would put the resolution somewhere in between the 100-240 loads because thats probably where the car spends most of its time during spirited daily driving. Increasing the resolution there can enable you to really make a quick & responsive part throttle spirited driving car.
Other than that, your map looks pretty similar to mine, with the exception I am spiking 2psi higher than you. My map mas looked similar to yours, for almost two years now on E85, and I still love it. Just small tweaks here and there to it is all I do anymore.

Thanks for all the replies guys, I tweaked the load 100 row and I think Ill leave it at that for now. I cant really tune it to the edge of knock then back it off because the knock sum is all over the place all the time.
Thanks
