Someone on here adapted a distributor the 4.2 vortec intake camshaft and is running megasquirt.
I'm running megasquirt (MS) on another engine type for 3 years now.
Currently MS doesn't support coil on plug ignition - its on the list to do but not ready yet. A solution to this is either adapt a dist. or install a ford EDIS wasted spark system that IS supported by megasquirt. Just recently MAF is now supported from a 2nd s/w variant, which will make tuning high horsepower engines much easier.
The h/w to support coil on plug is most like 8 to 12 months out before its ready for mass consumption. Once it is ready all the headaches of trying to make the stock ECM work will go away.
I'm currently running MS2 which is the most current module, as of this week its ready for mass consumption. This module has the hardware built in to support CAN bus which will allow multiple MS2 to talk together using 1 as a master and others as slaves. Where this will lead is to electronis trasmission controllers, boost control, and most likely data loggers.
The MS2 is a progression toward the UMS system which when completed will rival or best any of the top aftermarket ecm's out there e.g. electromotive.
