Yeah so I was looking at my LM-1 and Xd-1 gauge, and I was just wondering....does everyone keep the Lm-1 hooked up in the car at all times in order to work the gauge, or did you guys also buy the standf alone gauge system with the LM-1. If you keep the Lm-1 with where do you keep it and intresting ideas?

r0gu3

A couple people I know that run the sensor all the time had a seperate bung welded in the DP 20-24" away from the turbo.

You can keep it in all the time but you may have to replace the sensor eventually. For the best readings you want to mount it as close to a 12 o'clock position as possible on the downpipe and furthur away form the turbo(s) like r0gu3 mentioned above (so it wont ever overheat). At the very bottom of the DP right before the midpipe flange there is a good place where you cant mount it at almost a verticle position.

Dont know much about the gauge. I sold my LM1 before they came out with the guage just because everyone kept asking me why I had a 'Nintendo Gameboy' in my car. I did think about tearing it apart and trying to mold it into the dash, but opted away from that. Thinking about going with the techedge unit now.

bah....so in other words I am goign to have to find a really creative way to mount this fat *** thing out of sight.......damn it, its huge....See I htought it was going to work like. I order the XD-1 and the LM-1 and then I just plug in the LM-1 when ever I need to datalog soem A/Fs for tuning...But apparently I am gunna have to keep this bad mama jamma in the car the entire tiem to work the XD-1....bah. ah well....hmm taking it apart and molding it to the car ey.....hmmmm..sounds danergous...there has ot be a good reason as to why its soooooo ****** big.

Can't the XD-1 function without the LM-1? I have the LM-1 and I just made a DIN faceplate to mount the display (and the electronics) below the CD player. Now all I can see is the display, no more huge LM-1 brick lying around. There is no good reason the box is so huge, just poor packaging. I can post a pic this weekend if you want.

yes please

the XD-1 needed a seperate setup to function on its own. I thought if I got the LM-1 with it I was gunna get a setup that would allow m to just simply plug it in and out to the sensor and have the XD-1 runnin at all times. But the XD-1 does not work like this. Apparently for the SXD-1 to function it needs to run from the LM-1 to the the XD-1 and out to the Comp....retarded...So takign apart the LM-1 isnt that much of a problem I take it?

The LM1 is really easy to take apart. And my DIN setup doesn't require any more than unscrewing the boards from it. I don't have any good pics of the actual thing yet, but here are some views from CAD. The only drawback to this setup is that I don't have the battery connected anymore so it can't store data. This isn't really an issue for me, but it would be easy to add a battery mount too.

so in other words you now have to guess where the record and calibrate button are?when you reach under...though that is not a problem since I happen to have the XD-1 which controls both buttons i believe....not a bad set up actually thanks for the Idea...I just took apart the LM-1 it was very easy actually but I was still wondering where I would shove the buttons in oter to use them and fit them without getting things in the way. There is no point for you too put the battery in now though is there? Or do you take that unit out of your car and only use it when you calc A/Fs? I'm assumign you have a laptop when you tune...

I do not reach under to use the buttons - I simply don't use them. Right now I'm only using it as a display because I'm still breaking in my engine. When I get to tuning, I'll be using a datalogit and laptop to log, so again I won't need them. If you wanted access to the buttons with a setup like that, you'd have to mount buttons next to the display on the faceplate and run wires to the buttons. Quite possible to do, but unnecessary for my purposes.

Xeros

Hmmmm so how are you going to data log the A/fs? through the data logit? Are you going to run the LM-1 to the Data logit?

Exactly.

I see I see....how are you going to hook it up, I have heard of this, but whats the point of the lm-1 if you could have gotten the XD-1 gauge setup and simply had run that thing over to the datalogit, isnt the LM-1 and A/F logging system?

AgentSpeed

I have my LM-1 tucked behind my passenger seat. It is out of site for the most part. I ran all the lines under the carpet and then I bought a piston case (gun case) to put the LM-1 in. Now all you see is a small black case behind the passenger seat. Once the seat is placed in the normal position it is undetectable. I have the add on gauge mounted on the pillar and mine stays hooked up all the time. It's been working perfect for the last 8,000 miles. My sensor is just before the midpipe flange at about the 10 o'clock position.

As for logging, I've got two USB cables coming out under the passenger seat.
1 for the datalogit which is also in the same gun case as the LM-1 and
1 for the LM-1 programmer. So far so good!

I would have bought the LC1, but the LM1 came with the car and it would kill me to buy a system whose functionality I already have. If I could have traded it for the XD-1 I would in a second, but seeing as that is unlikely, I made the DIN setup you see above. Connecting the LM1 with the datalogit is discussed here https://www.rx7club.com/power-fc-forum-47/inovative-wideband-o2-441157/ .

Here is my solution. You do have to drill a 1/2" hole in the bin to get it there but I don't use the car every day and it keeps it from getting hit. I velcroed a relay on the back side of the bin and ran the lead to the cigarette lighter. I do have my battery in the other bin so getting a power wire was real easy. This way you don't have to remember to turn it on and off whenever you turn the car on and off. I ran the output back up to the dataloggit and fortunately for me the sensor wire just reached. I velcroed the case to the bin that way I can take it out for repair, use on other cars or calibration.

As for sensor location I actually had just bought a Bonez hi-flow and I had a bung welded right at the front end of that so that it is far enough from the turbos, not to close to the cat and hastle free when it came to having to remove the downpipe. I mounted it exactly vertical but you should take some time and place the cat on the car to get the placement exactly right so that it doesn't hit the various braces and all under there but a hell of a lot easier than removing the downpipe.

Good luck!

bah i wish I had knwon about the ****** LC1 ealier!!! i WOULD HAVE BOUGHT THAT SUCKER INSTEAD!!!! I wonder if i can still return my lm-1 and just get the lc-1.
