LC-1 with no problems.

jermstyle

I’m leaning towards the LC-1 because I can install one in each bank for the same or less cost one of the other units. I also don’t want redundant functionality because EFILive can do everything I need. It only needs a wideband controller for input.

If you look at the Poll results though, the LM-1 is the most used wideband by users of this forum.

Are there any solid reasons why the LM-1 is better than the LC-1 for use with a scan tool like EFILive? I think the LM-1 is more for portability and stand alone logging.

yeh the lm-1 is if you want to swap from car to car or just read your afr without having laptop. i honestly wish i had gotten the lc-1 now.

Which of your criteria ruled out the FAST dual?

Can't really say about the ones I don't have.

For me the WB is only a tool that sees occasional use,
random vehicles & times. So I had no interest in a hard
mounted design.

You want to be sure that any unit you buy, has a self-
calibration ability. Otherwise you can drift out with no
way to correct. Units that are always in the pipe are
harder to calibrate and some I looked at make no mention
of it at all.

There are a lot of issues or potential issues with output
fidelity for logging voltage outputs, ground offsets and
gain errors. See a lot of complaints about LC-1 especially
but anything that shares heater and signal ground is
likely to have some degree of error introduced. You can't
take these tools on faith.

I think most LC-1 issues are due to installation errors. I've only seen one that was a failure out of the box, it would either read 10 to 1 or 20 to 1, replaced the sensor and it worked fine.

I've used an LM-1 for two years with no problems, no overheating ect. The only time they get picky is if the voltage is lower than about 12.2v.

I've used both the LC-1 and the LM-1. The LC-1 takes a bit more thought and time to hookup. The LM-1 took about 5 minutes to connect and get a reading, although it was stuffed in the tailpipe instead of in a bung.

Overall, I like the compactness of the LC-1 and the portability of the LM-1. I don't have longterm data on the LM, but I can say that the LC is pretty finicky when it comes to electrical and heat.

LC-1 for a couple of years with no issues.

I have a PLX M-300. It's an excellent wide band and I run it all the time. The analog output is linear and EFILive does a great job logging it.

I'm an aircraft electronics engineer and am familiar with this kind of technology. Most all of the WBAFR units are based on the Bosch Sensor which is inherently very accurate. Look for a unit that is packaged (sized) in a way that will be easy for you to use and that will interface easily with your logging hardware and software. Most of the units on the market today will work effectively for your needs.

We use Dynojets in all our FI cars.Easy to read dial when going WOT,extremely long life with cars having over 40k miles on them(FI).If tried all of them and had a few fail very early.

For bang for your buck, the LC-1 is at the top of the list. For idiot proof install, it is at the bottom of the list. Using an LC-1 really demands that you have a total understanding of how the thing works in order to get it to work correctly whereas many other products are worry free. Not to be judgemental but you really have to ask yourself, Do I have the time and aptitude to learn how this really works? Most of the people bitching on this and other boards about tuning issues, and knowing A/F is central to the process, are simply just not willing to sit down with the cookbook and really learn, they just simply want to haul *** thru the drive thru and choke down their super value meal.

I'd like to see how the new cheap $199 PLX stacks up against the LC1

LC-1 here. i got my first one in March of this year. i think i had issues with how it was hooked up (ie, grounds). i went thru three of them. every time i had a problem i got a RMA, sent it back and they sent me a new one. their customer service is first rate and that's very important to me. the last one i installed using the HPT interface ground (with goes to the OBDII connector) for the signal ground and the sensor heater ground i ran to the engine block. it's worked perfectly ever since. the only disadvantage is i have to have the HPT interface hooked up when running the engine to make the wideband sensor heater work. you can't run the car without the heater working or it wrecks the sensor.

I will say I got to meet i guess the owner of innovate at sema & seemed like a real stand up dude...product wise, although they've had some issues with their lc1 it seems like they've stood behind each one until the issue was resolved so I definitly give them a thumbs up for that.

That $195 PLX deal looks like an awfully nice buy....

My AEM would rank among the easiest to install and connect. All you need is to plug the wideband in and supply power and ground via a cigarette lighter adapter and you are done. Then for logging with a scanner, just plug one wire into the interface and away you go. I can install this setup on most any car, anytime in just under 1 minute. Best buy I have made and great customer support from the AEM guys.

What about the FAST? Is it not on the list because of the price or are there just not many people using them yet?

I can understand that you want to keep close tabs on your engine. I was just wondering what is the advantage of using a WB on both banks though. I notice that both of mine always run really close on the fuel trims and you can't tune the banks seperately with any software I have seen so far. So why micromanage the engine at this level? Why not choose the bank which runs the leanest and tune for stoich on that bank? It would make it easiest on your wallet at least.

Well, the only reason I went with the FAST is because I got it so cheap. The reasoning I have heard is that you get a more accurate measurement from taking the average of both sides.
