I hope mine didn't show up like that? It looks nothing like that in my tune file, or at least how it shows up

That is from your tune. At least the one posted.
how does that work? I shows up smooth on my computer.. How do I screen shot it from HP on my screen?
try this
latest adjustments
I really need help at this. Guess I don't fully understand it yet. Thought I had read up on how to set up tuning files but obvious that its not going as planned. Any pointers are appreciated greatly
You are only extending to 100kpa not even sea-level. No boost. The one I showed went to 255kpa.
think I got it this time. changed the row axis to read to 200kpa
new table, all screwed up... :(
It isn't all screwed up...in my experience, when you extended the axis hptuners just follows the trend of what your current VVE table is so what you can do is just bring up those areas that are dive bombing up to the rest of the table...at least for a starting point. Besides that really big dips is occurring at a very low rpm and a very high cylinder kpa so your car may very well not even see that area of the VVE table
this is my base, again lol!
Better,
So you understand you are saying with this image that your engine is more efficient at 6500 rpm under most manifold pressure conditions than at equivalent 3800 rpm location. Your engine efficiency usually matches torque as a general rule.
I'm just trying to smooth it out and go from there. I thought I was getting an understanding about what this table does, but you got me...
So if I were to lower the 6k area it would be better?
Not saying you should do anything. Every engine is different. Many things go into to this. VE is used in later engines because unlike SD it is designed to compensate for factors other than just manifold pressure. Here is a start.

Thank you helping me BTW! I would guess my table is a lot different than what you have. Im at sea level and super hot right now. It a really bad time to be messing with all this stuff but its so far off part throttle. More boost lower rpms is killin me. Basically when car is in normal shift mode (auto) more noticed in am, cooler air, car goes lean... simple not simple. At least not for me, YET!
With in inputs your ECM has VE table should not be any different for elevation, temp and other things. That is the beauty of VE over SD. The only input and calc missing is humidity. So no your table and mine will be close.
Our differences will be created by the efficiency of the motor (ability to pump air and combust fuel). Things like piston design, head design and porting, exhaust design and blower are the difference makers. All are highly modified on many cars including my ZL1.
