Title: KRMXN -- Maximum knock retardation Post by: littco on January 24, 2013, 08:48:00 AM Is there any benefit in setting this higher on WMI cars where by failure in the WMI can cause ingnition to be over the max retardation and Max CF's of 12 be reached even if more is required?

KRALH? just tossing out two tables which would show-up in a FR search in the relevant section. also. your thread title. ok everyone, let's take a moment to laugh at this amazing title. little things, people, little things. I don't know why everyone is so interested in KRANH and KRALH, they are for defining load and speed ranges for adaptation. Op, I'm not sure what you mean by benefits. How much are you thinking of adjusting it? The limit is there to prevent problems caused by retarding too much.

Just set up KFLAMKR/KFLAMKRL to add fuel aggressively post the 4.5 deg mark, and it will be OK. You should stabilize around 8-9 deg retard. This assumes running a lot of meth. You should also enable LDRXNZK and have it lower charge pressure when this happens. Personally, I like my Aquamist HFS-3 system with it's flow monitoring concept and ME7 map switching before shit hits the fan.

I double checked this because it is stuff that was floating around in the wiki for a long time and I never verified its accuracy. KRANH is but KRALH isn't I really should update the KRANH section of the wiki; i think i misunderstood what it does. KRALH really is load hysteresis Title: Re: KRMXN -- Maximum knock retardation Post by: jibberjive on January 24, 2013, 08:14:52 PM also. your thread title. ok everyone, let's take a moment to laugh at this amazing title. little things, people, little things. I always thought LAMFAWKR was a funny map, but apparently no one share my humor ;DTitle: Re: KRMXN -- Maximum knock retardation Post by: littco on January 25, 2013, 06:24:13 AM also. your thread title. ok everyone, let's take a moment to laugh at this amazing title. little things, people, little things. Not sure i follow... Please enlighten me.. To be honest unless I missed something I don't really come here to be mocked... If there's a problem with the title then I guess it's google translate issue as I copied and pasted it there, whilst actually taking the time to read and absorb the info from FR and a winols file..sorry if its not literate... Title: Re: KRMXN -- Maximum knock retardation Post by: prj on January 25, 2013, 06:26:35 AM To be honest I don't see the point in nehalem's remark either. What exactly is wrong with the thread title?
Title: Re: KRMXN -- Maximum knock retardation Post by: littco on January 25, 2013, 06:43:11 AM My point in all this, was I've seen a couple of cars now that have had issues with WMI and the controllers, as a result cf's have run at 12. Now whether that is actually dead on 12 or a theoretical 13-14 etc but only hitting the limit at 12 as this is the max you can't tell thus by increasing or decreasing it ie down to -15, it should the WMI fail would allow a safety margin.
Is it was just a thought...and if its way off the mark then so be it...

KRANH is but KRALH isn't I really should update the KRANH section of the wiki; i think i misunderstood what it does. KRALH really is load hysteresis They are both hysteresis deltas for KR adaptation.

Is it was just a thought...and if its way off the mark then so be it... You may want to implement other failsafes, such as prj's simple suggestion regarding LAMKR. There really is a good amount of options available. 15* should be ok, but you have to be careful with EGT's here. |
