I'm going to use the autotune feature of Microsquirt to set my fuel map (VE table). This system will automatically adjust the VE to achieve the mixture as defined by the target AFR table.
This is a 12x12 table. The Y axis is MAP reading (load), and the X axis is RPM. This table was auto-generated by this microsquirt calculator. What do you guys think? Is this a solid target AFR table or are adjustments needed? |

it is also better to start tuning from slightly rich
Lean -> hole in pistons Rich -> bore wash Hole in pistons happens faster than bore wash (IMG:style_emoticons/default/wink.gif) |
