Need help choosing a PLX Wideband
I am choosing between the PLX M-300 and the PLX SM-AFR with the DM-5 gauge. There is approximately a $40 price difference with the M-300 being the more expensive device at about $300. Anyone have experience with both of these modules? I did a search, but not much out there. They both seem very portable, but I believe neither has logging ability, is this right? This is not a big deal as HP Tuners Pro has its own logging ability sans laptop. Both units also have the wideband and narrowband output for easy hookup to the PCM.
Are there other units I should be looking at in this price range(less than $300)? I have already looked at the LC1 and the LM1. I like the complete plug and play setup of the PLX setups. Hook it up, select in HP Tuners and log. Both units are also cheaper than the LM 1. Also both are self calibrating which seems important to me.
Do these units use the standard Bosch WB sensor that the Innovate products use? Lastly do any of the sponsors carry these widebands? I would prefer to purchase from a sponsor of the board.
Thanks, Joe

I do see that the LM1 is on ebay for about $300 shipped, wonder if greenlightmotorsports will match this price.
I guess I just do not understand what the exact differences are between the two PLX setups. Only thing I see is the M-300 is an integrated controller and gauge in one and the other setup has the controller box and gauge separately.
Is there anyone using this setup on the street in a weekend toy? Just trying to get some feedback on it, hoping someone may be able to point out some possible drawbacks to running the setup. Suggest a better setup? This to me seems like a much better way to go over the PLX M-300 or the PLX SM-AFR. Cost a little more, but the features seem more than worth it.
Help me!!!
I really depends how much you'll use it and how much you want to spend.
FJO Racing have a nice dual channel controller also which works with both Bosch and NTK sensors.
Good luck with your choice,
The R-300 will function as my main gauge and help me get these damn vehicles properly tuned before its permanent installation.

So are you going to place it in the front 02 sensor position or a separate bung???

It will take some time to replace my gauges and have the PLX controller hooked up in place of the stock gauges. I will have to tap into the corresponding sensors that I want displayed by the PLX screen.

PLX SM-AFR AND Gauge GP prices.................
- that is the environment it was designed to be in
- there are no problems with leaving it in the exhaust without it being turned on or in use (which will kill it quick)
- there are less chances of condensation problems (which will also kill it quick)
- there is no need to remove it when not in use and replace the open bung with a plug

Look around. I only paid $259 for mine and didn't wait for anyone else to buy one. Unit alone is only $195.
Will I need a gauge, or would I just plug the wideband in the controller/laptop abd read it there??

No, you don't need a gauge. The gauge is just for keeping an eye on things after you are done tuning.
If you were to use a SM-AFR, you could add the cig plug. Then replace one of the NB O2s with the WB O2, but leave the NB connected to the original wiring and just hang it somewhere out of the way while tuning. You would have to tap in to the high side of the NB wiring going to the PCM (you could do this with one of those connectors that you squeeze onto the wire, like when you add trailer hitch wiring to a truck, I don't know what you call them, and then remove it when you are done). Then just find a good ground near where the PCM is grounded. And hook up the WB wire to your tuning controller. It's a lot easier than it sounds.
So is this the set-up that everyone that tunes multiple cars and incorporates a wideband uses?
If I use a gauge instead of running it through the laptop, can I just temporarly replace the NB sensor with the the WB sensor, and plug it in the factory plug, or does it have to have "custom" wiring each time you use it on another car?
I'm just trying to figure out how to use a wideband for tuning multiple cars/trucks
Thanks

You can't tune with just the gauge. You have to log the AFR in the software to be able to change the parameters. So, all you would have to do is plug into the cig lighter for power, and put a ground at or near the PCM (you could use some type of alligator clip on it so it wouldn't be permanent). Other than substituting the wideband sensor for the narrowband sensor, that's it, because the wideband would already be wired to the HP Tuners.
That is a lot simpler, huh? Sorry for the confusion.
