I'd stay away from an LM-2. General consensus on the net is more have troubles than don't. I was heavily considering one, when I ran across an extremely disheartening Amazon review from one of our members, Nigel Tufnel. My LM-1 failed all together after a couple years as well.
For a semi permanent gauge, I'd go Auto Meter or AEM. For something removable, I like the FAST box.
I had heard (read) the horror stories as well, and they use the Bosch instead of NTK sensor, but (knock on wood) mine was great all last year, plenty of street/track/race gas use. and for what I have into it, if it craps out, I'm not really at a loss.

Ideally I think you would like to log O2, RPM and MAP. I don't know if you can monitor MAP with with any of these tools using a carb tho.
Being able to see MAP and A/F helps to smooth out part throttle and transitions in your curve.

On the EFI it does monitor the map along with the AFR and rpm along with a lot more.. on a carb that might be rough without a data logger I was out in the shop running my ride so it would start the learning process and along with me learning this system... lots of data there

Wondering if the OP wants it more for track or street.
I think its mainly a street ride

If you're not going to get one with some sort of linked computer/box go with an AEM, price is good and they're known to be very accurate. I think I paid 160 on Amazon for mine.
Now I need to pin those needles, got to feel that heat Hear my motor screamin while I'm tearin up the street

does any of them read 2, O2 sensors? Like a right side and a left side?

Some are single channel and others have 2 to allow you to read both banks separately. I'd like to have a dual-channel, but will be using a single channel LM-1 when my junk is running again.

Yes the LM2 can be bought with two sensors. My LM2 has been flawless, it records to a memory card and the data is viewed on my computer. It will take up to five inputs and is supposed to be capable of reading OBDII error codes

just bought a LM2 my self and also bought the exhaust clamp so it can be used on other vehicles, also bought the rpm pickup and a couple of SD cards at best buy to store the info then plug that into a laptop,,,which I have yet to get, I down loaded the instruction manual from Innovates web site, and 50 pages later the printer finally stopped spitting out paper.

Yes I have read about this too on all the EFI calibration forums, one of the top tools the professional tuners use is the AFM1000 which is a laboratory grade air/fuel sensor which uses a high quality NTK o2 sensor which costs $1500. http://www.efi101.com/forum/viewtopic.php?t=8702&postdays=0&postorder=asc&start=0
The next step down from that was the discontinued NGK Powerdex AFX which is now replaced by the AFR500 http://www.bmotorsports.com/shop/product_info.php/products_id/2337

I agree with CAB and the quote at bottom Of course it depends on what you are trying to accomplish and what other equipment you have, as well as your technical comfort. For some, a vcr tape of a gage on their dash might be sufficient. For just monitoring a street car, a gage is enough. It would be like another dash gage. Glance at them as you like or need. Video if you need. That said... Wideband O2 (WBO2) sensors effectiveness as a measurement of Air Fuel Ratio (AFR) depends on the system they are attached to. Because of that, all of them can give false and entirely misleading reading in certain situations. Innovate's systems will often give an error code in such situations, which IMO is better than a false reading. Their system is also very responsive, so you can see a lot of detail. Datalogging is just what you think. Traditionally in testing it was a seperate device that would record information from the sensors. The old analog way was on scolling paper that a little pen moved up and down. The digital way usually involves very quickly checking each input channel and record it into memory. How fast is needed depends on whether you are trying to see each pulse down the exhaust on a very quick 1/4 mile car or a more general trend getting on the highway. * Innovate's LM1, LM2 for example incorporate both the datalogging function and the WBO2 operation into a single unit. However the LM1 did not log additional channels without a second auxilery device. * Inputs. In addition to the WBO2, on the drag strip an rpm input is very helpful. RPM usually just needs an input hookup that can recognize pulses. For tuning the carb on the street or non-straightline competion, both a manifold air pressure (MAP - vacuum for most of us) and a throttle position sensor (TPS) are very helpful. Having just one is still a big help. So having the option for two more input channels on the datalogger would be good if that's of interest. I've mentioned Innovate here because I've used their stuff. My experience with their loggers is that they are consumer grade packaging and pricing on an engineering product. It's not a plug and play, super easy to use. The older logger (LM1) works best with a computer that has a serial port. But the version of software that works best needs something newer than Win98 SE. Issues with the LM2 seem to be solved and seems like you may not need auxilery units to log the rpm etc. Over on the Racingfuelsystems forum, you'll notice racepack and innovate logs seem to be the most commonly posted and discussed. I'd check out those manufactures websites as well as FAST before deciding. PS. The reason TPS and MAP is useful in tuning is in figuring out which carb circuit is working under non WOT conditions. Say the car is at 3000 rpm and coasting, its idle circuit, wheras 2000 rpm on a hill might be 35% throttle and onto the mains. But without the MAP or TPS, its hard to know exactly what was going in when you look at the AFR log. By testing and keep good records, you can figure out what is going on but those two devices make it much easier. Quote:
Unless you want to try watching the gage rather than the road, or try hooking up a GoPro, or have a passenger with you while gathering data, get a unit with the ability to record.
And RPM data is also a near-must. Then your data needs to be on some kind of graph in order to make sense. So just having an A/F ratio line on a spread sheet is not much help. You will need the ability to manipulate the fuel line and coordinate it with RPM.
If you don't already have a data logger, do yourself a favor and get a wide band with RPM AND data record abilities. Believe me, after a day of tuning, making multiple changes and having multiple charts, the ability to have them organized in a comprehensive set of charts and the ability to toggle between them is invaluable.
I use an LM-1. Has Innovate worked through the initial issues that plagued the LM-2? If so, then that is the unit that I would recommend.

Can the LM2 read an alcohol car too?
