taking out fuel
what tables in tuner cat do i use to take out fuel at wide open throttle? im going to the dyno tomarow with my friend and his 383 ta. any tips for dyno tunning would help
thanks
thanks
Re: taking out fuel
%change to fuel/air ratio vs coolant temp at wot
and
%change to fuel/air ratio vs rpm at wot
heres the formula
WOT AFR = 14.7 / (1 + %Change vs Cool/100 + %Change vs RPM/100)
more info from the tuner help file
This table is the percent change to Fuel/Air Ratio used at or near wide-open throttle (WOT) versus coolant temperature. The values from this table and the WOT % Change To Fuel/Air Ratio Vs. RPM are summed to arrive at the WOT Air Fuel ratio.
The resulting air / fuel ratio can be calculated as follows:
WOT AFR = 14.7 / (1 + %Change vs Cool/100 + %Change vs RPM/100)
For the selected RPM, suppose the percent change to Fuel/Air Ratio from the RPM table is = - 5.1 and the percent change to Fuel/Air Ratio from the COOLANT table at the selected coolant temperature is = 22.7, then the approximate WOT AFR would be:
14.7 / (1 -0.051+.227) = 12.5:1 AFR
