Kmanager permits you to edit the RPM Index. I see several benefits from this but wonder what the drawbacks are.
To begin with it make no sense to me the default high speed RPM INDEX is:
3000
3500
4000 <<<
<<<< IF this is the area VTEC engages should we already be using the "250" resolution mode
5000 <<< Could we not go 4000, 4250, 4750, 5000 and create smoother maps?
5250
5500
5750
6000
6250
6500
6750
7000
7400 <<< why should this not be 7250
7700 <<< if you wanted to change scale and smooth be 7333 and 7666
8000
8500
9000
10000 <<< why even go here??? Or MAYBE I should set fuel to 0 at this stage as my motor is certainly blowing if I keep feeding it fuel
11000
Would creating a new RPM Index provide better resolution and presumably smoother operation?
BIG QUESTION, what happens when you load this to the ecu? Are there limits as to how many rows you can use? Does this all get converted or what?
RPM Index question
Re: RPM Index question
There are limits to what the ECU can hold. If you add something to the middle, it will "push" everything down, removing the bottom one. Whether or not KManager will still store the bottom row after it's been pushed off, I don't know.
As far as increasing resolution around VTEC engagement, I did (same thing, didn't have a need for 10k/11k indices with redline set to 8600). But after the fact I did realize that it really isn't necessary - unless you're seeing one particular lean/rich spot (or you think you could see gains by adjusting ignition/cam) "between" two existing points, the ECU will do a fine job of interpolating.
Your fuel/ignition/cam tables probably, for the most part, follow a steady curve. A perfectly smooth curve would be ideal - more resolution will get you closer to that perfect curve, but will also take more time to tune. The resolution they provide is sufficient IMO - increasing it further seemed (to me) to provide very diminishing returns.
