I've decided I am going with the AEM unit. Now the next step is figuring out which wideband setup to go with and just some basic information about what is needed...

If i get the 30-1000 then buy the AEM wideband it plugs straight into the ems or laptop? then it displays and logs on the laptop, or you can just buy the guage? What is the difference between single and dual channel widebands?

I would like to just keep a straight AEM setup but what if i got a PLX or innovative wideband. Will they just have a gauge or can you plug them into the EMS and have them log and display on the laptop as well?

Thanks - Any input is appreciated on different brands or models. I am a wideband newbie.

 

they can be wired up no wideband plugs into that ems directally even the AEM one needs wired in. i beleve the obd1 ems that has a wideband plug into it is the 1040u

You can wire it into the EMS and datalog air/fuel ratio in addition to seeing it in real time. The dual channel is meant for cars with a V engine configuration (Mustangs, NSX etc.)

Yes, you can set the AEM up to work with other widebands and it will datalog them as well. I'm pretty sure its programmed to read from several different manufacturers (such as FJO), but I'm not 100% sure since my laptop is back home.

there are a few aftermarket (i.e. non aem wideband) cal tables included with the EMS software

 

cool, how do the different widebands connect to the EMS unit? is it a plug in thing or does it just require splicing a wire?

 

Hook the signal wire from the wideband sensor controller to the primary O2 signal input on the back of the EMS (splice into the stock harness). You could also run the stock O2 sensor as the primary input and the wideband as the secondary O2 input, but if you want to run in closed loop (allow the EMS to make fuel corrections to adjust to a target AFR) I think the wide band needs to be wired to the primary input.

 

so if i get the PLX m300 i can wire it to the EMS to datalog?

yep! my techedge 2a0 is wired into my EMS and works perfect.

easy hook up, signal wire to primary signal wire as stated.. then power and ground and you are good to go

 

or you can get a 1040u

the U ems's have built in wideband controlers so the sensor just plugs into the side of the ems. no splicing required.

also keep in mind its a good idea to wire the ground for the external wideband directly to the battery. a fluctuating ground can skew the reading.

 

cool. I am going to order my plx m300 now...

 

For the money I would recommend the 1040u, if you haven't already purchased your EMS. As for PLX 300 it is/was fairly accurate but the self calibration mode is and was to me a little sketchy. I had my m300 for about a week before getting rid of it because it was consistently off by several tenths compared to both my friends AEM WB and techedge units. Plus alls you have to do with the 1040u is turn on the WB and it works.

 

AEM EMS + AEM UEGO gauge =

that's my setup.

I have the AEM EMS + Techedge 2.0a.. But im going to sell both of them for the AEM EMS 10-3040u with buildin wideband..

personally i don't like the aem wideband , it doesn't read very far into the rich region. and as far as the selectable list of wideband controlers goes i didn't even use that.

all it does is have a pre configured voltage vs. o2 reading table. The correct way to do it is to calibrate the gain on you aem ems so that you get the exact reading that the wideband unit is putting out. for example my techedge is in the aem list but all of the settings were way off. i needed to set my tech edge to output 1v 2.5 then 5v and i calibrated the gain so the ems was seeing the correct voltage.

i guess what im trying to say is don't just buy the aem wideband because you think it will be plug and play. it should be calibrated if you want your o2 readings to be accurate. i like my tech edge, can read from 7:1 to 19:1 a/f. and this is the case where any wideband would do , its just a matter of setup.

 

The ability to read further into the rich area is the only reason that I was thinking twice about changing it.. It only reads to 11:1 air/fuel which is fine for tuning and all but its eaiser to see how rich you are past that point instead of guessing..

My setting for my techedge were correct in the table, I did have to set the gain, one this I noticed is that if you power the wideband using the + and - that powers the ecu youll get a near perfect result..

 

i bought a plx m300

 

i planned on upgrading to a 1040 from my 30-1000..whoever has the best prices PM me..
