Gary,

I can't speak to the FiTech product other than to say during my preliminary investigations they lived up to a parts company sort of customer service/support experience rather than a supplier of a tuneable EFI system. The presale exploratory experience was bad enough that I didn't want to roll the dice with them on what the transition to an after-sale customer service experience might be like.

I looked at a variety of systems from the very nice, very pricey but very capable Motec and Haltech systems down to some less nice, less pricey alternatives. The last system I looked at was from DIY AutoTune which retails the factory-built MegaSquirt systems.

From a tuneability standpoint, these systems are a poor man's Motec or Haltech. From a support perspective, they are extraordinarily well supported by both the online Mega Squirt forums and more significantly some excellent YouTube videos that show you in 15 minutes (sometimes less) how to implement various features in your specific application.

From a feature perspective, they support everything that the higher-priced systems do and there is typically several YouTube how-to videos available for the particular feature.

Several of the really nice features include the fact they use the original Ford sensors so you are not buying EFI vendor sensors that are actually repackaged OEM sensors with outrageous markups. Although they use the OEM Ford sensors they also allow you to use any sensor you want and provide you the ability to use other sensors by modifying the sensor calibration data (not hard to do).

Beyond the sensor niceties, one of the real biggies for me was what they call their Plug-n-Play versions. These systems come with an OEM connector that allows you to use an OEM Wiring harness rather than having to build your own harness from a pricey aftermarket unfinished ball of wires. The installs are blissfully simple as is the first start experiences.

The system provides you with a choice of either Speed Density, MAF based or Alpha-N tuning models, easy scalability for engines of any displacement, cylinder count and firing order up to 10 cylinders. If you travel to locations with more than a 1000 ft change in altitude, the MAF based fueling model will automatically compensate for the altitude change where the Speed Density fueling model will not. Additionally if you want to run eight stack Weber look alikes, the speed density fueling model will be best for you. Engine displacement and injector size setup is stunningly simple in their excellent incudled Tuner Studio tuning package. The System also comes with a data logging capability and I think I paid either $75 or $80 extra for a wireless Bluetooth connection between my laptop and the MegaSquirt ECU for wireless tuning!

The whole package (with a lifetime warranty) is $1500 click here=> MS3Pro PNP

There are all sorts of built in engine saving features and a boatload of add-on whizzy stuff if you are into that kind of thing, but IMPORTANTLY, the basic package has you completely covered. If you like turbos, flat shift features, multifuel capability, rev limiters, launch controls, anti wheelspin capability, electric throttle controls, variable cam timing and a boat load of other special features, they are all there — for $1500.

The MegaSquirt code is among the oldest of the commercially available EFI fueling logic offerings out there going back into the early 1990's and possibly earlier. It is quite mature and robust.

The $1,500 price point, The ease of install and setup, the rich programming feature set, the myriad of engine protections and this list just keeps going, makes for a very attractive product offering.

Beyond the basic EFI system you will need to purchase a fuel pump, fuel filter, fuel injectors and fuel pressure regulator and suitable high pressure fuel lines. I recommend you use the teflon lined fuel lines because they do not allow any gasoline vapors to accumulate in the garage. Several of the AN fitting suppliers now have non teflon lines they claim do not weep gasoline, so you might want to check them out also.

When it comes to determining what size fuel injectors you need, if you need help I can provide you with an excellent injector sizing tool in Excel format. The spreadsheet is too large to post because of forum file size limitations so PM me if you want it.
