Default wideband display v. 2.0

My voltmeter wasnt displaying the output from my LM-1 accurately. Some A/F's would show ok but others wouldnt. Shitty chinese voltmeter.

Went to Auburn, AL this weekend and reunited with an old friend - my long lost custom remote LM-1 display. It was a good bit of work and involved hacking my LM-1 all to hell. Thought the display was forever lost but I gots it back and installed it in the miata tonite. Also made a cool spot to mount my LM-1. Still have to tuck wires and run the LM-1 it's own 12v.

That's a very cool display. I assume you have a microcontroller stashed somewhere driving it?

Basically what I did is disassemble the LM-1, found the closest match to the display on mouser.com and then I cut the wires going to the stock display in the LM-1 and attached them to a male printer cable connector and attached a female connector to both the mouser display and the stock display, so I can switch back and forth from the internal to external.

I don't know much about electronics - just enough to get myself into trouble. If Im not mistaken, the controller is on-board with the displays - if that makes sense anyways. It's only like 17 wires.

Need to get a new sensor though, mine's getting a bit flakey and has been passed around more than..[think of someone clever and insert here]

Edit: Found some pics of when I made the external display connectors

Cool stuff.
An LC1 and DB gauge is so much easier and cheaper though.
Do what you have to though.

Yeah that is a nice bonus but with a laptop the LC1 and AEM UEGO can both datalog values using that one application who's name is alluding me.
His AEM F/IC has 2 min of built in datalogging as well, sweet little unit.

How do you like the F/IC anyway?

It's pretty sweet. It's got an OK tune on it but its still too rich in boost. I thought I had the narrowband manipulation fixed but I realized last night I dont. ECU is still striving for stoich under 4k. Pain in the ***. Gonna re-check my wiring for the o2 tonite. If I cant figure it out, im gonna put a pressure switch that opens a circuit at like 0.1psi to remedy that.

I gotta send away for some free wires from AEM that'll allow me to datalog my A/F along with everything else. With a laptop you can datalog all channels basically forever.

I figured you could datalog with a laptop and run with it till you maxed out your harddrive, not that you would, but you could.
It's a pretty interesting solution for NB's wanting to get some boost while retaining OBD 2.
