The sweet taste of apparent low cost, apparent simplicity and visual similarity to a carb system we are already familiar with fades as the buyer attemptes to gain functionality he thinks ought to be present in his system only to find it is not.
Easily the best fully featured system available right now is the MS3Pro Plug and Play systems available from
DIY Auto Tune <=clickable. Pick any one of the three Ford PnP systems they have to offer and you will not be disappointed! They are the pooor man's Haltech, Motec — and you don't need $8-10 thousand. They are actually affordable!
They plug right into an OEM Ford wiring harness and use OEM Ford Sensors. BBuy the Harness from Ford where they are still available or scrounge one out of a salvage yard and you are good to go. The 03/04 SVT Cobra unit comes with an excellent base tune that delivered somewhere around 440 HP out of a stock O3 Cobra.
The DIY AutoTune route is easily the shortest way home from both a price and installation point of view. The ECU comes with absolutely excellent tuning software and data logging software. When you are on their site check out the list of features the EFI provides, it is stunning.

Malcolm Install The story plays out exactly the same.
You can easily get snookered with half steps and throttle body this and someting else that sort of installs. This stuff just works — right out of the box! It gives you access to every tuning variable but does not require you to use the more sophisticated stuff unless you want to. It is for sure the short way home and there is lots of YourTube video support along with an active user community on their website.
Check out the Vids, you will bnot be disappointed!
BTW the EFI unnit allows you to plug in your rngine displacement in liters or cubic inches and will work for any sized engine. Injector sizing is also fully customizeable, high impedance, low impedance, low flow rates up to multi thousand cc's per injector flow rates.
This stuff is the short way home.
You and I think very similarily Tommy. If the units are reliable where did all the cores come from for rebuilds?
If you are considering EFI check out the MS3Pro stuff I was yacking about above. It works no matter what size or power level the engine, supports nitrous, supports, turbos, supports superchargers, flex fuel — the list just goes on and on.
