Total cost was around $10.00 plus an old cigarette lighter cell phone charger. The CDM volt-meter is powered by 5v so the charger was used to step the car's 12-14v to the 5v it needed.

Gutted a cigarette lighter cell phone charger for the 12v to 5v bits


Tapped into some wiring for 12v during IG key position


JBWeld to the rescue

ahhh how is this a wideband where does it get it signal from ?? not ---- talking i just missed it if its a past thing

 

this is just the gauge.

you will need to use a WB O2 sensor along with it to get a correct signal

 

come to think of it, why would you need to gut a cig lighter adapter?

does the "gauge" not accept a 12v power signal and then a 0v-5v signal from the WB o2 sensor?

 

i think its this isnt it ??

the gauge needs a 5v signal in order to operate. I tried it on 12v and it just wigged out. I got my LM-1 outputting 1.0v at 10:1 and 2.0v at 20:2 so if the gauge says 1.5 I'll know i'm running stoich.

hmmm just realized I might need to make a modification on the decimal place...anywho

bitchass - I'm using a LM-1. I would have gone with one of the JAWs but I got my LM-1 the week they came out. Poor thing has been through hell.

 

well if it works than stick with it lol

 

Next time if you can't find a old cell charger, you can spend a $1.50 at radio shack.

Thanks dude, I'll remember that.

So yeah I fucked up and realized I needed a gauge with a higher resolution to show A/F properly. Im bidding on a panel with 0.01 resolution. Shouldnt be a big deal to re-wire.
