Often less is more. Map5 will adapt down after addl runs I suspect.

map 5 adapt cause pcm got knock and it lower the timing?

how map 4 is not adapt ,we can t tell pcm to not adjust timing? I think.

can you create a knock count on data we log? it nice to see what realy happen.

can I change value on user setting to get better result in map 5 , not 16.5 psi but with 9 or 7 timing like you see in my log, I have probably 96 oct, why it down at 7 timing?

thanks

The field called "avg ign" is used to trend the closest thing we have to a "knock count". The higher the number the lower your advance is from the max targets and the less boost map 5 runs.

I also use this software, very helpfull.
First I've done a real dyno run, then I've calibrated the virtual dyno software in order to have the same numbers, and then I test each mods by running the virtual dyno, always on the same road.

I'll test Map 2 and Map7 to compare to my map5 curves...

Virtual Dyno was proven to be really accurate actually (Real Dyno compared to VD)
You just have to have to make sure all the settings are right (Weight, Tire Diameter, etc)

I actually know the creator of the program and he keeps asking me to race his gt500!
Super nice guy who is always willing to help out if you have questions about the program.

I've found map 2 to run stronger than map 5. If its pulling timing it's not making as much power. Put some race gas in it and run map 7. You'll notice it pulls damn good.

So, to jump in here and make sure I understand the feedback from Terry/others:

Map 5 may have made less power than Map 2 on the dyno because it had not had time to "learn" the fuel/temp/etc, and would eventually have adjusted the variable parameter settings down to the same settings that are "hard coded" into Map 2. And that if Map 5 had gotten a few more 3rd/4th gear full pulls, it would have made similar power to map 2 (11 whp/34 tq more)?

Blown-WK, can you elaborate on finding "map 2 to run stronger than map 5", and describe your steps/method? how much time did map 5 have to "learn" the fuel/atmospheric in your car prior to your measurements? Did you try map 5 first, and then map 2? vice versa?

map 5 try higher boost so the timing is lower, we need timing for horsepower

17 psi at 8 degree of timing give less power than 13 psi at 12 degree...

learning not help if we do 10 log at map 5
it won t adjust better....

we need boost and timing for performance, need 17 psi but with 12-13-14 of timing

sorry I know my English suck

I felt the same way. I was trying out Map2 vs Map5 i think Map2 pull stronger! It was very humid and rainy today at 80's deg. I guess the condition gotta do something with it?

I've made few virtual dynos with first Map5 (blue) and then 2 runs with Map2 (red and green). same road, same time, same conditions.

pretty big difference, no ?
and I can feel it too. the Map 5 is muuuuuch more powerfull than Map2.
I'm running 50% E85.

Wow 14psi at 6000 rpm and more .map n54 is really better than n55 tune

Can you post your log? To see timing

for the map5 tune, I've set max boost at 17 psi instead of 18, because of the 50% E85.

with those high IATs (OEM intercooler, still), the boost is lower than with more fresh air.
