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? |

I think some among us are WAY over thinking this stuff. (IMG:style_emoticons/default/av-943.gif)
What is manifold pressure?? Vacuum! Those kpa#s are all just various levels of vacuum until you reach 100kpa. That is atmospheric. To even suggest that a traditional vacuum signal going into a vacuum can on the side of a mechanical dizzy can out perform in ANY way a completely digital and infinitely tunable modern MAP system is ludicrous. MS is instantaneous advance. There is always a slight lag with anything mechanical or even electro/mechanical. Once you get that motor dialed in with either an EDIS or COP ignition system, you will look at ANY distributor as a HUGE compromise. Even a tunable one like a Mallory does not compare. Just as carbs are a compromise compared to tunable EFI system, so is a dizzy to tunable fully digital ignition. |

My point was that the retard is the factory's "fix" to overcome the (mechanical) limitations of the distributor. |
