| There are a lot of off-the-shelf fuel injection controllers on the
market these days. So why would I want to build my own? COST! Plain and
simple. Why spend $900-$2500 for a controller, and still need to add a bunch of
stuff, when you can get an open architecture, highly re-programmable, super flexible
controller , for around $180!
Granted, the Megasquirt requires a bit of study,
and a lot of reading to get going as desired, but the flexibility is utterly mind
boggling!
The system code I'm running is MSnS-E,
which stands for Megasquirt and Spark-Extra. This is quite literally, a second
source programming version that has taken the already super flexible system and added even
MORE features.
A list of the features that you can control with this ECU and the 'Extra'
firmware, is as follows....
