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? |

If you're going for max power, then you will need an AFR in the high 11s low 12s where you are on the gas during hard WOT acceleration. My car leans out on cruise to 14-16 around 65-75 mph in high gear. Once I blip the gas it goes back into the 12s for power. I've got more tuning to do on mine. Now that I have a CHT gauge installed I will be better able to lean out the mixture to go after better fuel economy w/o worrying about cooking the heads. That table will get you started, but richening will give you power. |
