Website looks pretty good, but there is no menu or anyway to navigate off of
the main page.

> The philosophy for the MegaSquirt system was simple: provide a
> controller for fuel injectors which can be adapted to any application,
> without having to write embedded code or understand the details of
> engine controls. In addition, provide all the schematics, software,
> algorithms, etc. to everyone - keep nothing hidden. Provide enough
> information for anyone to duplicate the system with ease. This is not a
> commercial unit, but directed to DIY applications. Also, the circuit is
> going to be featured in an upcoming Circuit Cellar issue.

> In short, MegaSquirt is a fuel injector controller (fuel only, no spark
> control is provided - this is to come later in another system) which
> uses standard sensors (coolant temp, manifold air temp, throttle
> position, oxygen, trigger from existing ignition system) to perform
> batch fuel injector (two banks) pulsewidth control. A flash-based
> Motorola microprocessor (MC68HC908GP32) is used for the calculation of
> fuel and injector control. Additionally, host software has been
> developed (widows-based) which allows the run-time adjustment of control
> parameters. All information for the system is available on the web site
> above.
>
> This is not a system under development - MegaSquirt is a complete
> functional system which has been tested on two applications. I have
> MegaSquirt installed on my Jaguar (Chevy 350-powered) and is now a daily
> driver.
