Why two? One is good for 185 HP. The Ford V8s used a single "two barrel" CFI unit.

Here's what my engine looked like -- at the crossroads of old-tech and new-tech (1984):




I had a '84 police cruiser, and an '85 cruiser (these were the size of a Falcon). Like these:


These were basically a Mustang 4-door (same chassis, suspension, engines, etc).

Both had 165HP. The '85 LX had 185 HP. It was impressive power in 1983-1984, but by 1985 was getting dated. (1985 was the year of the 210 HP Mustang V8 with holley 4-barrel carburetor -- and the 205 HP Taurus SHO naturally apirated 3-liter V6).

Anyways, here's somebody put two CFI on one V8:

Just a thought but maybe CFI wouldnt need a destributor input because it doesnt really need to know injector firing order or timeing. Does any one recon converting this sytem to a a15 is possible

This guys engine is a mazda OHC running the carb throttle making 127hp at the wheels confirmed on popular dyno and had a datto 1200 with a worked a15 making 115hp at the wheels with the same setup.
It works but I think he used a microtech lt4 or something and Im more into making sure it works with a common junkyard computer.
Will keep you guys updated when he contacts me.

this looks like a great project for someone who is willing to give up a weekend and a bit of spare dough to see if it will work I was thinking earlier about a gas research carby with a turbo draw through set up but have no idea about what needs to be done to the head to prepare it for a gas only conversion.
Also is this CDI unit similar to the carby shaped injection set up on the Opel/Holden Barinas

dont post anything else D, you have the perfect number

1200 posts. Ah, the perfect number ... unless you prefer the B10 ...

Hmmm... Im thinking this coupled to an old Microtech D4s or D5 computer could be the ultimate low-budget EFI... I just happen to have a D4s (and a Haltech F9), but it's mapped for a 12AT...

I know my chances of getting it remapped ...

Good work on finding this!

By the way - if anyone is interested in using the factory electronics this link may prove useful:

What have you looked into as a replacement lower flow rate injector that will fit the bosses?
I think Cordia Throttle Body Injection is a setup worth looking at. Its a good size throttle body, has good sized injectors for an Aseries and is an allrounder suited to NA and Boosted applications with its high pressure injectors.
Maybe a bit harder to source than the ford stuff though, but I do think the injectors will be a problem with the ford setup especially with 2 on an Aseries.
How slow can you make Injector pulses so to try and make the injectors suit that way?
Low pressure fuel doesnt leave much scope for controling flow by pressure adjustment.

i think pulse width is used to control the fuel flow not the pressure in a standard EFI system. to modify the pulse width i would think you would have to mod the ECU. i didn't know so many cars had CFI

Do you think so? Obviously you dont understand what I wrote.
Both fuel pressure and injector pulse width are used to control fuel rate. Whats a fuel reg used for?
If you cant get lower flow rate injectors - you will have to control fuel delivery by other means. eg, change pulse widths on's and off's.
When you take a fuel system off a 4litre motor and use 2 of them on say a 1.5litre motor, I would think fuel supply would be in excess. So brings the question " how far do you think you can change the injector pulse widths to reduce the fuel supply?" Is it not a big ask to reduce fuel supply from that capable of supplying an 8 litre motor - to that of a 1.5 litre motor?
Reducing fuel pressure would greatly help reduce fuel flow - but since this system already used low pressure - it doesnt leave much scope for pressure reduction.

Thats just my thoughts. But Im just a windsurfer who goes with the breeze.
