E48 V34 AEM wideband

[thethinkingman]

Evening, does anyone know if i can wire my AEM wideband lambda into my E48, i have V34

Yes you can but you need to find out if you need a 1v or 5v scale, some E48 can accept 5v, check with dta or make yourself a test rig with a 0-5v potential divider to slowly increase the voltage on the lambda input. If it stops in the software at 1.2v you have a 1v version and will have to recalibrate your AEM to output 0-1v only. You can do this on innovate stuff so I assume AEM will also.

Thank you

I'm not sure if you can recalibrate the AEM's output, some of them dont allow it.

Innovate despite all their other problems is very good in that respect

My aem has 4 settings, from what i have learned P4 is narrowband so i would assume one of the others will be WB

Yeh but what does that do to the output? Narrowband will simulate a standard lambda sensor, you need the wide band 0.5 to 1.5 lambda range, outputted to either 0-1v or 0-5v volt, depending on what the E48 can accept.
