It usually cycles from one to two sometimes up to five bars from the bottom (lean) on the freeway. This is supposed to indicate something like 17:1 or so but there is no way this cheap afr gauge is anything but an approximation. Normal cycling without efie is right in the middle as it should, cycling up and down on either side of stochiometric a few times a second. This is with my dual plug head ford 2300cc motor. The nissan 2400cc wouldn't run near this lean, but it only had a single plug head.
As always, tune the efie to your particular engine, the instructions are pretty accurate actually. Using an afr with the efie in my opinion is a great idea, you really need some feedback for how the efie is affecting your fuel mixture, seat of the pants tuning leaves too many opportunities for error.

Thanks for your reports! its just what i want to hear!
Presently i´m checking my EFIE and AFRD and i have obtain a lot of info about my ECUS, chips and engine!
First i had to change my lambda sensor for a new LS 6 BOSCH, my EFIE AFRD were not flickering !
My old sensor was sluggish!!! the voltage was steady like a wideband sensor lol!
This was the first best result for experimenting with DIY EFIE AFRD!
Second i have to adjust de delay time for restart in hot without problems (15 seconds is right!).
And like you said, the narrowband lambda sensor is oscillating permanently but when one understand this
is a very nice led read and the leds isn´t all lit, not, only three and the mostly only one!!
My EFIE DIY is not the same eagle research, is the Better Mileage Mixture LM3914 based circuit.
Its really works very fine! and i modified it building into an AFRD with ten leds correspondingly exactly
to 0.1 - 1.0 volts .
And I can use it for reach the mix at 0.6 0.7 and 0.8v AFR correspondence.
And this is the first and more important step.
Now i go to the second step : CYLINDER DEACTIVATION but not a DOD or MDS or VCM or ACC systems only my
INJECTION CYLINDER DEACTIVATION ICD ! (i will not fake my valves in order to avoid pumping loss).
I has a Ford Splash v6 3 lts great machine! and a Ranger 2.3 like yours great truck!
And I think the best for your economy experiments is the ICD, you do not need feed 140 brute horses to
go at downtown postal office to go a letter!
And the best is that the EFIE will not to accept the mixture enrichment by the ECU (since the exhaust will be 50% more leaner).
One of the most important at the ranger 2.3 is put on the engine 8 spark plugs bosch premium 4 electrodes!
BTW when i start running the Fords i only experiment to how to disconnect the default speed limit!
and was fine not anymore shut down the injectors at 100 miles/hr .
