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.

Yah... but it doesn't have built in datalogging....

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 ass. 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.
