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
They are both hysteresis deltas for KR adaptation.
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...
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.
