Interested in removing my efi speed density setup for a fitech efi carb. Money isnt the problem and I'm going get a standalone trans tuner ecm. What would be the issue going from speed density to a efi carb setup, doesn't have to be a fitech can be anything similar, Holley etc. I know fitech makes a whole master kit that gives you everything to get going. Anyone ever done this on a speed density motor.

I’ve yet to see any of those TBI fuel injection kits beat the reliability of a stock multi-port fuel injection set up.
What have you done to the motor performance wise? If it’s mostly stock I don’t see any gains by going to a TBI set up

All stock motor but want to build a turbo setup up in the future. I mostly want it for tuneabilty because the speed density doesnt have much aftermarket. I could convert to OEM efi from the 5th gens. But price is nearly the same. The fitech and similar setups have way less wiring and can be tuned to your heart's content.

Factory ford maf is easier in my opinion. Fully tunable with moates quarterhorse or tweecer setup. Mustang a9l computers are readily available or fiveology racing offers nice kits for a good price.

All that's required is a few repins on the ecu, injector harness and running a few new wires for the maf sensor. I converted my 86 speed density to a mustang a9l setup and its running a highly modified 347 on factory tune with a calibrated pro m maf sensor.

I plan on tuning for optimal performance but it runs pretty well on the factory tune. The ford maf computers are incredibly adjustable.

I run one on an SBF. It was converted from carb. The down side I see is losing the long runner intake. Guys who have switched to carb could probably comment on that.

With an automatic and a mild cam it should be pretty straight forward. Sticks speed up engine transition states and takes some tuning to eliminate bugs and lean spots during shifts.

Whatever you do dont run one of these junk fi-tech or similar setups for forced induction, especially turbo. Ive been running the Megasquirt Mustang 86-93 pnp unit on my bronco and is the best, easiest, user tunable setup you can find for the money.

Hey there,
I will be doing the same thing on on '90 but using one of these: Summit Racing® MAX-efi 500 Fuel Injection Systems SUM-240505 . i will also be starting with a new block, Mine has been sitting for ten years so i want to start fresh. Good plan going with the trans tuner from what i have read and you may also want to look into a new distro, i will be adding that with a MSD box. Good luck and keep us al posted.

This looks like a great option. Appears to be MS3 but in a more user friendly package?
