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? |

Bubble, do you monitor your head temps or exhaust temps?
Do you dyno your vehicles? do you do comparison tunes between different A/F rations? What you are claiming, 16+ cruise is OK if its properly tuned (this includes timing like you mentioned). But the OP is looking for baseline to get things going, for that purpose its better to be SAFE. In that instance 14.5 is the target for cruise +/- 1 and 12.5 is the target for WOT. This is for your TYPICAL engine. Aircooled engines, being aircooled, need to have their a/f ratio a bit more conservative than watercooled engines to prevent potential overheating. Granted high 11's might be rich in your eyes, but I like to keep my engines cool when running WOT. All that being said I havent tuned an aircooled engine in a long time and primarily spend my time with big v8's and turbo 4's and typically shoot for 12 flat under WOT. |
