great - now on to the total timing display issue!

hey Morris, i know you just posted a how to on the D-cal Table file.... but.....
can you make the program bark back at you (load bin file first or something like that) if you click that "make d-cal table file" button if you dont have a bin file loaded or even not allow it to be selected without a bin file being loaded. this will save me from having to walk simon through it over the phone when he is at the track and is all mad cause he cant get a bin and table to use in D-cal cause it looks all crazy.

Which point do I adjust?
-downloaded the stage 4 lm cals
-unzipped
-started mpt2 and opened up the template
-pressed compile
-opened up the bin file
-selected settings, create dcal...
-exited mpt2
-started dcal
-scrolled down to the table you show and this is what i got --->
ill have to try it again when i get home. i have remote desktop on my phone but its a bit slow on 3g sometimes.
done. will be in next release... or even not allow it to be selected without a bin file being loaded. this will save me from having to walk simon through it over the phone when he is at the track and is all mad cause he cant get a bin and table to use in D-cal cause it looks all crazy.

Would you guys forget about Dcal already?!
I like d cal. Simple. Effective.
So is MpTuner. MPTune is a little more complicated but not much, it's working pretty smooth now. Takes a minute to find everything and get used to, but once you do it's nice.
I like mp tuner. Very easy to use.
Wow a Simon fix!!!! didn't think that was possible
Does this screen shot interest anyone? Take a good look at the table group
wow. awesome!
double wow
hook us up bro!!!

I'm officially amazed.
Killer!
i need some advice on how the mapmul table fits in and i'm probably missing some other calcs. heres how i have it working currently for the full throttle graph.
1) add the map advance (WOTMAP) and spark advance (GOVNER) together based on the applicable psi and rpm intersection.
2) compare the result in 1 to the minimum allowed advance (RPMLMT) and use the higher of the two.
3) compare the result in 2 to the maximum allowed advance (SPKLMT) and use the lesser of the two.
is this the right logic so far? if so i just need to know how to fit the mapmul in.
lmk.

oh ya - other that changing the WOTMAP table to HOTMAP for the part throttle, what other "calculated" 3d tables do we need to set up. i'm sure there are some fueling ones? i'll need to know the formulas for those also.
(and thx to cordes for providing a spreadsheet to help me get off dead center!)
Sounds right, at least for the LM cals. Rob L. will know more I'm sure. I think he mentioned something about advance multipliers in SBEC's not long ago, but it might just be in SBEC II cals.
That all looks great!
The calculations are right - except for MAPMUL. MAPMUL is a scaling factor for WOTMAP or HOTMAP when the lookup value from those tables is negative. It has no effect when the MAP advance vale is positive. So, if the MAP advance lookup value is -4degrees, for example, and MAPMUL is 1.25, then the actual MAP advance is -5degrees. But, at a lower RPM, MAPMUL might be 0.75, which would make the MAP advance -3 degrees. That value is then added to the RPM adance (GOVNER). Basically, this gives a true 3D shape to the timing tables.
I don't think our fuel tables need a 3D display. We don't vary the A/F vs. RPm, so a 3D representation of the fuel table would just look like an expanded 2D table. No 3D effect.oh ya - other that changing the WOTMAP table to HOTMAP for the part throttle, what other "calculated" 3d tables do we need to set up. i'm sure there are some fueling ones? i'll need to know the formulas for those also.
The one thing that would make the 3D calculated tables truly awesome, would be a compare function. Maybe a non-shaded overlay of the surface? Just the oulines in a diferent color? It would be very handy when tring to copy a 3D cal to a 2D codebase, for example.
So i just need to test the return values from wotmap/hotmap and, if negative, multiply them by the appropriate mapmul multiplier before adding to govner. i'll get that added to the formula. do all the cals have the mapmul in them (even if they have the wrong common name)? how about the wotmap,hotmap,spklmt and rpmlmt tables?
