One of these days...
I was going to find a wrecked 5.0 L mustang and laterally transfer the brains, MAF, harness, injectors and possibly the rails to a sHARk.
Availability and programable are the two operative words here.
From what I've read a good running stang and sHARk have very similar torque and HP curves.
Baselining may or may not be necessary.
Think of the number of stang brains laying around as opposed to the limited number of ALL sHARk brains. Get to work John Speake... there's money and HP to be made here.

True the mustang is very close to the 16v but is the firing order the same? What about referencing a cam signal? Does Ford ignore the 02 reading after 2500 RPM? Opening up the intake with a MAF is all that's needed. I bet it can be done $500-700. Lot cheaper w/o software involved, just an analog converter.

Doesn't the L-jet have a temperature input to give density correction due to air temperature? Then if you just replace the AFM with a MAF you'll end up double counting the density change due to air temp. The car would run rich on cold days and lean on hot days. Not sure if this effect would be big enough to cause a problem though.

Let me BUMP this old dog.

I was looking into doing this on my 82 with a euro motor. Has there been any improvement on this conversion???
Thanks

If you retain the stock L-Jet its not possible. The brain is too old with too little brain for a MAF.

Your best bet is to convert to standAlone EFI like MS

Brad, Let's go to the wrecking yard this weekend and find a mustang we can glean parts from!

If you want one of the Split Second systems that John Kuhn spoke about earlier in this thread he has an extra one now. You can contact him through Pelican or his website. We took one off of one of his brothers twin turbo 16v car to convert it over to Megasquirt II. The reason for the conversion was that the split second only allows fuel tuning. It has no way to adjust the spark timing. I wouldn't use this system if I were you. The other aftermarket systems such as Megasquirt etc are much more sophisticated.

Correct me if im wrong (ive been on a streak lately!), but isnt a pre 84 euro engine going to be CIS anyways? those use a mechanical meter plate instead of an air flow meter.


Cool to know someone got it to work but at that point you would be 2/3 the $ into a decent MS setup.

Brad W

Correct, the motor came with CIS but I put it in a 82 with L-jet. I used the larger throttle body and plenum with the US runners.
The only mods at this point is I had to fit the throttle position switches to the throttle body and enlarge the u-bend.

How did you route the cold start. I keep hearing that the Euro heads are drilled into the exhaust vs the US heads being drilled into the intake ports. This means that if you assemble the Euro heads with an L-Jet system and hook it up just like it is on the US model, you will be dumping the fuel from cold start injector into the exhaust.

I have never heard that, but will check
