Some of the Megatune pages (Click to expand)

Hot start idle settings are here
Warmup wizard
Rpm limiter
Knock threshold. A curve can be put in if your sensor has a variable output.
Knock retard settings
Another way to look at real time display
Inlet air temperature spark retard
Extra advance when coolant is cold
Acceleration wizard, I've set it somewhat like an accelerator pump for now
Oxygen sensor settings
Automatic mixture control lets Megasquirt adjust the ve table to match what is set in the AFR table

Megasquirt 70 degree start and idle stepper page

This page is where the idle stepper is set. On startup the squirt opens the stepper all the way and then steps closed to the corresponding temperature of this graph. On a hot start its different and is set on another page.

This 25 MB movie is a start from 70 degrees CLT and what can be on the real time display. the gages can be swapped with a whole bunch of others.

AFR and Spark tables

Above is the spark table at the moment. It is the same one we used with the carb. Knock sense will retard it by various amounts.

Air fuel ratio table megasquirt is tuning the ve table to. Using a wide band O2 sensor lets the squirt have this kind of range. Not limited to 14.7 AFR.

Got port fuel injection running. Still have to set enrichments and cold start.
Listen to the q jet at throttle snaps!

Megasquirt install

Took three nights off on vacation. I have hope to get multiport fuel injection installed and at least running. Some setbacks so far wiring errors and a stuck injector. Should have had it running today but some of the linkage had to be modified. Maybe tomorrow?
