Lotta fun with Megasquirt, Autotune, tunes while you drive Options

[DNHunt]

I downloaded a newer version of Megasquirt with autotune. It uses a wideband O2 meter to adjust the air fuel mixture to a target while you drive. The targets vary according to RPM and manifold vacuum. I have a high of 14 at cruise and a low of 12.6 at WOT. Megasquit keeps adjusting until the amount of fuel gives the desired voltage from the O2 meter. It speeds up tuning a ton. (IMG:http://www.914world.com/bbs2/html/emoticons/smilie_pokal.gif)

It's cool to see it changing without any key strokes on the computer. There are a couple things to consider (there always are). Tuning is only as good as the O2 meter and the air fuel mixture is just a number pulled out of the air. It will not tune the ignition side of the ECU. So, when I get everything sorted out and the engine well broken in it still goes on a dyno.

Thanks for the response Dave. I posted my questions here: http://www.msefi.com/viewtopic.php?p=95991#95991

After reading and reading and reading it does sound like we can use MS II configured with the high current coil driver and and either points or equivalent (optical, hall, VR) using a stock locked dizzy.

It sounds like MS would pickup the positive edge of the waveform and control dwell and advance among many things. Advance can lead the leading edge of a spark event and output directly from MS to a stock coil. It sounds like the noisy input problem is easily solved with the Ed Capacitor(C12).

Any comments? Do I make sense or am I dreaming?

If this works it is WAY easier to implement than EDIS.
