Tuning clarifications

I'm currently using my 7 as my dd and have been trying to get a bunch of the enrichments correct. First is the accel enrichments. Looking thru the tuning guide on MSextra.com(http://www.msextra.com/manuals/MS_Ex...ual.htm#accel), in the chart at the bottom of the acceleration enrichment section, they seem to be saying that higher values for tpsdot or mapdot indicate slower throttle application, where to me a higher change in TPS/second would mean the throttle is being opened more quickly. Also, is the "accel time (s)" (on the acceleration wizard page) the amount of time that the acceleration enrichment is applied for (or decayed), making a value of 0.2 equal to 0.2 seconds; and by changing the "accel timer" (under accel decel settings) to cycles, would this change the "accel time(s)" number to cycles, so 0.2 would mean 2 cycles?

Also, are both the warmup and afterstart enrichments applied at once, or is afterstart applied first, and warmup after the afterstart time is up? The car runs well enough once warm, but getting it there can be difficult.

I'm pretty sure it goes from crank to afterstart to warmup ... individually and respectively. I've always used secs for accel ... never tried cycles ... and I think im currently at .4 or so secs =)

I'll have to look into that... a higher tpsdot or mapdot *threshold* means you have to hit the throttle quicker before enrichment is actuated... a higher value in the actual tuning table for accel enrichment correlates with a faster throttle stomp.

and by changing the "accel timer" (under accel decel settings) to cycles, would this change the "accel time(s)" number to cycles, so 0.2 would mean 2 cycles?
Yes.

Also, are both the warmup and afterstart enrichments applied at once, or is afterstart applied first, and warmup after the afterstart time is up? The car runs well enough once warm, but getting it there can be difficult.
I believe ASE is on top of WUE... so they both happen at the same time... then when ASE turns off, only WUE is left.

hmm interesting Ken ... I guess it ase goes by so quick its hard to tell ...

about the .2 cycles part (this peaked my curiosity, going by cycles instead of time) ... does cycles continue on by .1 forever? eg .5 = 5 cycles 1.0 = 10 cycles etc ...???
