I started with a bigger post, but then realised that the US and Aussie EECIV/TFI/ CFi isn't really like anything else. It has aspects of Geo, mOPAR k Car and Nissan 3.0 v6 TBi in it. We used the CFI 2-BBL system in our 1988 to 1992 3.2 and 3.9 OHC sixes with EECIV and TFI, it works fine and is reliable if you follow Fords fault code logic. And it was able to make 162 hp with just two injectors like yours, and being non ODBII EECIV, its pinouts allowed it to fit any car. I think the post Mike and Hot Rod did on the Maverick would have been great if they had added a 350 dollar Offy intake.

I'm subscibing, and takin a personal cup of STFU.
A tripower to me is the worst porting system I've seen, but it works, gives power, and part throttle economy. And it lookes great! Electronically managed by something that can power three of those kind of Geo Metro/Nissan Pathfinder/Chrysler K car injectors, and running open and closed loops from an o2 sensor, it would be killer. Running the injectors means you can't use the stock EECIV/TFI/CFi, its got limiatations, but I learned from Ak Miller and Impco that you can over rule a stock EECII/EECIII/MCU/EECIV system with a system of relays, and a computer that allowed the stock PWM computer to run, and collect fualt codes normally.The 1985 Impco manual tells you how to do it on 2.3 OHC's, F150 4.9's. The HSC and HSO is excluded, but you can use the same system.
Those guys used the stock low volage, low amp Ford computer with a few relays and a means of driving the injectors to open and close loop the system.
In your case, a Megasquirt would propably be able to drive it. You can run three oxygen sensors 12 inches down the extractor pipes on 2, 4 and 6, running off the headers, givening feedback to the the EECIV, you just have to condition the overall ratio.
So you just need to have a go. If Hot Rodders like AK Miller could make the 1981 to 1985 fuel delivery system work with dual fuel propane systems wthout triggering fault codes, then you can too. The pre check engine light systems were a lot of fun.
