Mega Squirt / Micro Squirt
 

Has anybody here got one of these? I'd love to here about it!

I've been aware of these product for some time, and was looking in recently. There has been significant progress in the ongoing development of them. They are circuits designed to control electronic fuel injection on a do it yourself basis. Mega Squirt is a board you can add components to to create a custom controller. Micro Squirt is a complete sealed unit with fewer features. Ultra compact with high quality water tight connectors designed primarily to run just batch fired EFI, though there are ways to run ignition also.

Am I hearing a big yawn??? Well, don't fall asleep too soon.

These are for experimenters, and basically adaptible to anything. You have access to the entire fuel map, and can change the look up table that is used to control the pulse width cell by cell, or in blocks using various advanced techniques such as interpolation. At the same time you can view a dash board showing the various parameters such as RPM, Temp, Throttle position, Mixture, etc. An autotune function apparently creates your initial fuel map...... You must have a Windows computer of some kind connected to configure it all.... A windows tablet would be perfect.

This is a hypermiler geek's dream come true..... I believe harness adapters are available to allow you to tie in to your existing system in place of the existing ECU. It is designed to interface with most common components, particularly GM. You can build an EFI system on any vehicle if you are clever enough to mount the injectors and build fuel rails, install the TPI, MAP, etc.

My interest is in building an EFI on my 1960 Ford F250 with a '56 Thunderbird Special 312 engine........My other interest is in working with WAI (warm air intake) in an environment where I have control, rather than trying to outsmart a computer. I believe the REAL benefit of WAI is two fold. One is reduced throttle drag, and the other is higher effective compression, in other words higher compression pressures at lower output. Your intake pressure is higher (lower vacuum actually), and the result will be higher pressure and temperature near TDC prior to ignition, which should result in improved combustion efficiency.
