How can there be just one map for either or? UNLESS you blend the maps at intersection? Low map would not be sufficient for high rpm ops. High map would not be sufficient for low rpm ops. What am I missing/not seeing/not understanding?
I appreciate any and all the help, I can not tell you how much.
EDIT: I think I meant what you meant (I think we meant the same thing..)
(Day 1) 2 maps: One for Low, one for High - both idle to 8,000
Determine when you want VVL to kick. For instance - 4.25k
(Day 2) 1 map: beginning half is your idle to 4.25k low parameters from day 1's low map, second half is your 4.25k to 8k High parameters/map from day 1...

The lift and duration change is near instant, so that's why there is no "blending" between the maps. You run on the low lobe map until you kick the cams over, then immediately go full high lobe map. With something like continuously variable valve timing like newer VTC/VANOS/VARIOCAM etc. you use percentages of blend between two maps depending on what your cam timing is.
I'm not sure why everybody here is so stuck in the 90's way of tuning of changing the values drastically in the map. Yes - it works, but it's not the ideal way to do it because you've got to retune things if you ever change your VVL switchover point. With two tuned maps you're good.
Personally I'm going AEM Infinity 6 on my car. I think it's a great price point for its features.
