Hi,

Here where the confusion lies, and what I think is right if someone can confirm?

Recently go the AEM system gauge +wideband (30-4100) correct me if I'm wrong but it has the controller built in (in the gauge its self) and i think this is all that is needed to log/tune/use in the EMS SERIES 2 and to display the AFR on the gauge???.

And also have the inline controller (30-2310) on its own obviously but it does the same thing except it doesnt have a gauge attached to it, so essentially I have two kinda of controllers with two sensors attached which do the same thing!!?!

In the EMS when i select digital gauge ie the gauge (30-4100) it just brings that up in the list, however when i select the inline controller 30-2310 it brings that up and '4 channel uego' and 'analog gauge' automatically - i cannot change that.

SO 'i think' at this moment intime just need the aem gauge system (30-4100) attached and wire(s) from it go to the EMS? and just chose 'digital guage (30-4100)' in the EMS for O2 #1?

Thanks

 

You should be able to use the analog output from either controller. Just use the proper calibration for whichever one you choose.

 

You need to only run 1 wideband o2 sensor, not two. If you want the wideband gauge, run the kit with the gauge, if not run just the inline wideband kit.

What you could do, is sell the wideband gauge kit, install and use the inline kit, and buy an aem serial gauge. The serial gauge will display the wideband values just like the wideband gauge kit, but the serial will display up to 17 other sensors if calibrated correctly, which the wideband gauge kit does not do.

as far as syncing the gauge to the AEM EMS, you need to verify that the wideband voltage output matches the wideband voltage the EMS sees.

I have not used series 2 yet, but I did this many times on series 1 equipped cars. You have to use the voltage offset option to get the numbers (wideband 02 #1 voltage) to match the voltage the wideband inline kit is sending to the ECU. You'll need a multimeter to check this. Plus, I am not even sure if voltage gain can be adjusted on series 2.

When in doubt, call AEM electronic technical support!

 

There is no gain option on series 2. You simply need to edit the o2 cal.
