Let's see your fully tuned timing maps

Hey Guys,
Here's my first map. It's FAR from fully tuned. I just spent some time scaling it to suit my car for right now. There were some goofy little sections where timing went up and down. I smoothed things out the best I could. I'm hoping to do some logging this weekend and actually make a few changes. Let me know if I did anything stupid.
Again, this is a stock Tephra V7 Evo 8 map scaled, interpolated, and smoothed out.

-Too much negative timing at peak load (2000-3250RPM, 220+ load)
-Also you could maybe reduce timing at 6500+ RPM / 200-250 load
-Cruise timing is quite low.

Thanks for the input.
Where are the harsh jumps? Maybe I'm missing them.
As far as your other suggestions, I haven't actually tried to tune anything out, yet. Just smoothing the stock map. I'm hoping just to take care of some knock this weekend. I don't have my wideband, yet, so I won't be doing any A/F tuning, yet.

aggie, keep an eye on the 3d shape. this is an example map. you are on teh right track, once you start tuning and seeing where the timing needs to be WOT you will be in good shape.
i did this from a stock map, and its my next flash. the values are +-1 or 2 degrees every where else but the WOT power curve which is identical from my current working maps, Where I am not, has been an evolution of the same map shape for two years, so I started back with a stock map and worked from there.

[QUOTE=domyz;10809819]-Some jumps are still too harsh.

-Cruise timing is quite low.[/QUOTE
Hes right i posted my map in here last few pages check out my rom, you want a smooth transition every where no more than 3 degrees timing between when rpm increases. I still have to change mine someone mentioned at peak rpm keep timing 1-2 degrees not so many jumps
Your peak load at whatever rpm should be around 3-4 degrees then work your way from there but as your load decreases and rpm increased add a degree, but your redline rpm and lowest load point yor car goes to should be around at 10-13 degrees not sure where mine is at
Refer to merlins evo tuning i think highst degree of timing is 13-15 at peak rpm and lowest load "7000 rpm load =220 fall off"

Eek peak load at 3-4 degrees is rough. If anything on 93 start with 1 degree and go from there... 3-4 could be peak torque but even that sounds high to start with.
I do this for my car: 250 rpm increments, 1 peak load 3500 , and 13-14 up top usually 7000. Interpolate vertically and that's an easy timing ramp.
Every car is different and an 8 is gonna be even more so. But that's my merhod and I'm just sharing.

That's about it but that is alot of timing. I wouldn't run that high unless my pistons, comb. chamber and exhaust valves were ceramic coated. Too much heat going on right there...

.... but I don't think it will yield much MPG gain. What is widely known here is that for running high cruise timing and get better MPG you need to run leaner AFR aka open loop.
I run full time open loop (15,7afr) and 42* and I gained about 5% economy. Not too much but still enough to be worth the long tuning process. Also you don't need to mess anymore with the trims which is good for me: I'm in the process of converting to speed density and that open loop mode is really making things simple. Little note about SD, the throttle response is awesome for now, I can't believe my car is smooth like that. Throttle release is completely another world vs MAF, no more major decceleration/bucking when BOV opens.
sorry if my english is bad,
