Hey I was wondering if I could put an air/fuel gauge on my 12v... I think they're electric gauges, so where would I hook it up? There's no computer on a 12v right?

Fueling around

Diesels use a pyrometer in the exhaust manifold to measure Exhaust Gas Temperature or EGT.
Air fuel ratio is easily done with a visual on your right mirror. If the truck smokes you need more air.

i think what you really mean is.... "IF IT DONT SMOKE, YOU NEED MORE FUEL!!"
SORRY! had to be done!

The air fuel meters are worthless even in cars, unless you get a wide band. But in any case they hook up to an oxygen sensor which your truck doesn't have. Diesels are always running lean, unless its blowing out smoke which most of us are. lol So unless you just want something that flashes worthless green and red lights don't waiste your money.

Yeah I wouldn't spend the money on one either, they are more for gassers anyhow!! Like said above........no smoke you're lean........LOTS of smoke you're VERY RICH

Haha... Yeah, I didn't think it would work either. But I have an extra space on my triple gauge pod and I wanted to fill it up. I'm going with a tranny temp gauge... I ordered one from hptrucks on ebay. It's been about a month!! I'm ******...

I ended up requesting a refund. It took way too long!! I tried calling for 3 days straight, no one would pick up. So I sent about 4 emails only to hear back telling me to call them. So I called and someone finally answered. Then they hung up on me when I politely asked for a refund! I had to call twice. I couldn't believe the lady actually hung up on me, so I called back and said we got disconnected. She was like: "yea, i heard you..."

At least, they gave me a full refund with shipping. Apparently they've been getting a lot of neg. feedback during that period. Don't know about now, but I would never deal with them again.

I Started a thread on here about them warning anyone here about them and it was removed?hptrucks has over 300 neg feedbacks I was just trying to save some guys on this site our head aches I'm still waiting a month later on a buy it now?

wcbcruzer

Honostly just call them up and get a refund. I doubt they'll send you your item.

To answer the original question, yes you COULD put an air-fuel ratio meter on ANY ENGINE but like previously stated....won't do jack ****.

An air/fuel gage basically measures exhaust temp in a gasser. the leaner the a/f ratio, the higher exhaust temp, the richer ratios lower exhaust temp.
