I quite dislike the digital boost gauge I have..
Numbers go wayy too fast to comprehend.

I've really only run one wideband setup, a FAST unit designed for temporary use for tuning. That said, I'd think for tuning, a dial might be more useful. The reason being that you'll see big transients easily with an analog gauge swinging where a digital display would be very hard to get any meaningful information from while you're driving. Sort of like checking a potentiometer with an analog ohmmeter versus digital: it's easy to find bad spots because you'll see the needle stutter, where with just a digital reading you have to process the numbers you're reading, and you might miss it if you move too quickly.

With that said, I did just buy an Innovate LC2 with digital gauge. I picked that one because it was the cheapest controller combo. I think the analog setup was $50 more I guess you could switch gauges down the road. One big reason I wanted the controller vs. standalone gauge setup is it has two outputs. So you don't need a second sensor, and what's more, you can program whatever you want for the lambda output. I'm going to try setting a leaner lambda for fuel economy, maybe just as an experiment; we'll see. Another advantage with a WB controller is the data-logging capability. I also bought an SSI-4, which gives you up to four potential inputs. I plan to set it up with RPM, MAP, fuel pressure, and maybe duty cycle. I'll be my first foray into date-logging; hopefully it proves to be a good tool.

This is the AFR controller/gauge I use for about 10 years or so:


Bought it here used and the sensor hold up well till this spring. After sensor change works like a charm again.

Easy to read and even has a green backlight (backlight color is switchable) very close to stock 931 gauges

Green backlight? That’s awesome!
You still running that car hard all these years?
Yours is a top example of a relatively stock 931 engine holding high power reliably..
