V1H,

Thanks for taking the time to analyze those Map curves.
My Awgd8 modified #3 seems to reach the maximum allowed number to feel the gain in the low end power at 1/4 to 1/2 pedal push. I basically felt that the number I put on the 40% - 60% flow potential is at the max/passed the limit to feel the gain from low end up to mid range RPM. Although, the mid to top end power can be felt.

So far my favorite MAP is the AWGD8 # Blend 2&3. You can see I tried to have variation of line angle to feel the change in power. The lowend has steep climb starting at 25% low potential. (About 1/4 pedal push) In my 5 speed AT tranny ( using manual mode) the power start at 2k RPM at 1/4 gas pedal. If you noticed I bumped up the curved to feel another power in the midrange and tapers of a bit at 3/4 of the curve graph. Then steep it up again on the top end to feel a continous power all throught the power band. Wstar map is too smooth were I could feel a better lowend initially and tapers off towards the top. I understand his point about touchy throttle input and I am actually doing the opposite, since I dont have a close gearing ratio tranny and I try to compensate an early throttle response that can be felt all through out the power band. A lot of trial and error changing those numbers, it is hard to explain, but I could feel where the power start and how far the pedal is push and the sound of the engine (less strain or smooth) by playing the throttle table. Still all my modified MAPs were tested at 7.6K RPM and I honestly feel smoother. (No jerky feeling or bogging issues)

My problem is I do not know how my map behaves on the G37 since I designed it for a 5 speed A/T. 3.5 liters VQ35HR engine....??? I only have one member here commented that my MAP #1 is more aggressive on the midrange vs wstar but still smooth..

BTW, i wish wstar can enlighten us with your question. I could be wrong, but my feeling about those negative numbers might be the a buffer when you let off the throttle.... I have no clue, but you know how the power behaves when you suddenly downshift and left off the throttle... It smooth things up... ????
