fn1036b - inferred load

Unread post by PaulC-turbo5.0 »

what is the purpose of this function? I have never made any changes to it because reading the description it says its only used if the MAF has failed and its not mentioned in any of the write-ups so i've always thought it has little importance. I've saw it mentioned on the forums for other strats so its got me wondering lately.

I would just dial it in without the above question using the histogram but its seems like its giving me unrealistic correction multipliers? if the corrections are indeed incorrect any idea why?

Totldst is for newer 94+ strats that actually have the table

in gufx i created it so you have to click the histogram down at the bottom that says gufx for it to populate actual load

then you plug the actual average load in to the table

its only used when the maf fails for gufx

ok cool this makes more sense. I checked out that histogram before but was thinking the values were multipliers so it still didnt seem right

ill get it adjusted even though ill hopefully never need it lol
