How do i adjust the fan shut off temp with the fan hysteris. And what is the Pe table, and what does it adjust. Thanks Prorac1.

 

fan hysteria is the temp the fans come -3 degrees. so if you have the fans come on at 80c when the temp gets to 77c the fans turn off.

pe mode is

%change to fuel/air ratio Vs cool.temp wot
" rpm at wot

the formula is in the help menu on tuner cat. under tables and look for the to tables above. and in one of these table it has the formula

it is used everytime you punch it. it called PE mode (power enrichment mode. it is a target A/Fratio the pcm tiys to hit when you go wide open throttle. but when you go wot if the last blm is above 128 the pcm add that to the preprogramed A/F ratio.

so you need to get the blms correct to accuratlly get the pcm to try and target what you want.
