Re: help settings for 390s
Simple math will get you a starting point for tuning if you're using an AFC..
Your stock injectors are 240cc, you're going to 390cc. What is the difference in flow? 38%. So, you set your V-AFC to -38%. But how did you get that number? Good question. When finding the percent of difference, you take your base number, and divide by your increase number. Basically, divide the lowest number by the highest. Then subtract 1. Example: (240 / 390) - 1 = percent of increase. This is the setting that you use as a base. |

Re: help settings for 390s
yup thats what i;ve read in the past aswell.
390 - 38% = 241.8 thats for stock like fuel settings. I would like to add, to this calculation, dont forget that u have to add EXTRA fuel when u dip into boost.. so idle = -38 1k = -38 but like 2k you might only need -30? understand? if u look at the AFC settings post they look like this... (example is for 450cc DSM's) idle -47 1k -47 2k -40 3k -38 ETC... |
