I have the AEM meter. Been using it for about 6 or 7 years with zero problems.

Although it is working perfectly, I recently bought an AEM analog read out gauge to replace it. I just grew tired of the digital readout gauge which looks out of place in a vintage car in my opinion.

I'm not looking for a permanent installation (but have also been looking at the AEM). I just want a way to help dial in the carb a little more "scientifically" than smell and seat of the pants feel!

I guess I could always get a buddy to sit in the passengers seat and hold it!

 

you'd be surprised how valuable it is to know the a/f ratio under the many different driving conditions that one experiences. My limited experience prompts me to advise installing the AEM wideband meter somewhere under the dash, if only for a month or so. Then decide if you want to remove it.

Thanks Z. That's a good idea, and relatively simple and less expensive that the options I was looking at.

 

I have had the LM1 for years now. Just tuned a 73 302 two days ago. Never had an issue.

 

Candoo - from what I have seen, the LM-1 was much less touchy/finicky/pick an adjective. With the LM-2, there seems to be two groups of people, those who hate it and those who love it, not much in between. The problems I have been having with it pretty much covers the range of those who hate it!

zray - I kind of like this:

It can monitor A/F and vacuum as well and has a built-in data logger with USB cord. It's overkill, but does everything I want.

Now to find a place to install it...

 

Over the winter I installed bungs in my exaust for O2 sensors. I will be re tuning the mach with the bung locations as opposed to the exaust probe I used in the past.
I like those gauges as well but no place to mount...Glove box ?

 

So far the only thing I have come up with is steering column with a cup mount...

 

Not on my Mustang... but on my '99 Lightning, I run a Glowshift wideband that has digital read out, and also has an LED. Honestly, I find it much easier to notice the number rather than notice the LED blinker.

A lot of people in the Lightning crowds frown on Glowshift because they are cheaper, but mine has been very reliable and I haven't had any issues with it, or the vac/boost gauge that I've been running for a bit over a year.

 

I use a Innovate MTX-L on my 347 for logging and it's never failed me.

 

I have an LM-2.. it's always worked... IMO the gauges are nearly worthless except for being pretty.

In order to be meaningful you need something that can log a/f vs rpm.. the LM-2 can do that.

My thoughts as well except that after 4 weeks, two returns, too many tech support calls to count the damn thing won't get past the logo screen and just locks up. Their tech support appears to be clueless.

The AEM I listed above has data logging vs RPM capability. Still haven't decided on anything except that the LM-2 is going back.

 

FAST one is okay but its so big and no place to put it, ive got mine resting on passenger seat most the time. I want to get rid of it and get a 2 1/16 gauge.

 

Im using the dynojet wideband commander for my setup. Its has a full sweep gauge and is nearly identical to my autometer gauges in the dash. Comes with software for data logging and has programmable led.

 

I like the looks of the analog black face gauge. It would match the gauges I have now perfectly. $529 is a lot of money, but in this case maybe you get what you pay for.

How long have you been using it?

 

I ran the AEM 30-4100 on my 65. I wrote some datalogging software that logs against time. I was working on a solution to take the tach signal in the sound card on a laptop but never got motivated enough to finish it. It's a nice enough package - graphs the data from the meter using RS-232 to USB convertor.

 

I'm using the LC-1 for my Megasquirt and have the XD-16 chained in the loop. No issues with it since I went EFI 6? years ago.

 

I'm in the same boat as you when it comes to the LM-2. I really wanted to pick one up, but after reading so many bad reviews I had to stay away. With my luck I would of ended up with the lemon. Sucks since their LM-1 was such a hit. I ended up with the AEM Analog Wideband Uago O2 sensor and I'm pretty happy. I would of loved a self sustained unit that could be used on multiple cars, but couldn't find one. I went with a cup mounted on the steering column and installed the gauge with a quick disconnect connector. I was planning on being able to use the gauge on other cars, but after final install I doubt that. Heres my set-up

 

Well, at least I know I can fit it there! I don't need it for other cars but hadn't really thought about installing it permanently.

 

I have had it installed about 2 yrs now. When I had the car tuned for my setup it was dead on with the tuners. I know its a little pricey ,but everyone I talked with highly recommended it. Not saying there isn't a better setup, but its really all I need. There are usually some for sale on SVTPerformance.com or www.modularfords.com that are priced reasonable.

 

Thanks wildstang. I'll take a look at them. BTW - your car looks great! How did you manage to get a big sig pic? It made me re-size mine!

 

Finally got the the retailer to take the return of the LM-2 so that's settled (hopefully - haven't seen a refund yet).

Decided to go with the Dynojet Wideband Commander on a column mounted gauge pod. Should be here this week. Keeping my fingers crossed that this works out for me!
