Yea. I had to disable it completely by maxing KFDMDADP and KFDMDARO

It will have to stay that way until i can log the other ARMD variables (mkar and nmod in particular)

Just broke 400whp on 91 oct, 85F IATs

ARMD is totally disabled. I can't figure out how to properly tune it out, so it stays off (for now)

I'm happy where the car is for now; need to drive it around and clean up FTs anyway (just went to EV14 @ 3bar)

KFDMDADP 0x1de1c 8x6 16 bit
KFDMDARO 0x1de7c 8x6 16 bit

all FF's in KFDMDARO for the cheesy fix. I have KFDMDADP also ff'd out but probably shouldn't

I expect the REAL fix will be in KIFZGHG, but i won't be able to tell for sure until i get a few ram locations and log (PLEASE tony/setzi/phila help me out!)

i'll have an updated xdf/kp soon.

Was zwout following zwbas or zwsol with ARMD intervention?

mostly zwsol (except when zwbas < zwsol, which is only occasionally)

are you saying i should try to get zwsol up?

ARMD is causing zwsol to fall far below zwbas

I'm thinking if i bring nmod up high enough with KIFZGHG it should send zwsol over zwbas

word.  its nice to see this being solved.  could you possibly post tunerpro screenshots of everything necessary to add this to the XDF.  there's a good bit of stuff I've added to one of your old XDF's that I should probably send you for the sake of merging.

Thanks nye, I will do this tonight and post screen shots of everything for the basic kill.  Had a successful night out last night with logging and all that.

I think setting KFDMDADP to all ff's is probably unecessary. i think you want to preserve dashpot judder damping.

A basic kill is probably doable in CWARMD bit 2 (13->9) as follows:

i THINK this is whats CWARMD does:

bit 0 determines if the clutch state should be allowed to halt AR and re-initialize the rpm model. Stock is enabled

bit 1 determines if the clutch state should be filtered for this re-initialization. If 0, it is unfiltered. If 1, the rpm state has to go from not increasing to increasing (B_tpnmot), or increasing to not increasing (B_thpmot) for a certain amount of time before the clutch counts as "not pressed" after being "not pressed". Stock is disabled.

bit 2 allows B_lsd to allow B_in to turn on B_tvars for TVARS time.
bit 3 allows B_dash to allow B_in to turn on B_tvars for TVARS time.
Setting bit 2 to zero is probably equivalent to setting KFDMDARO to all ff
Setting bit 3 to zero is probably equivalent to setting KFDMDADP to all ff


bit 2 allows B_lsd to extend AR by TVARS after B_in goes inactive. Stock is enabled in the g-box i have. I do not know the m-box location.
bit 3 allows B_dash to extend AR by TVARS after B_in goes inactive. Stock is enabled in the g-box i have. I do not know the m-box location.

The simplest total kill is probably to set TMAR to something really, really big - AR only enabled if engine temp is higher

RPM based kill can be done via:
 
raising NARLLA (based on gear) - AR only enabled if RPM is higher

or

raising NARASTG and/or lowering NARAO - AR only enabled for RPMs between this range

however, this also kills dashpot AR, which you probably dont want to do. I think the best quick and dirty kill (until i figure out otherwise) is to ff KFDMDARO

the question remains though, should ARMD be disabled? I got more power when I did, but what is the tradeoff?
