Report Tuners Rejoice! Free Tuning For M4.4! in Performance Modifications Posted September 6, 2016 23 hours ago, Boxman said: Tiny word of caution on the Ecotrons Accurate Lambda Meter - if you're looking for an actual fast GAUGE, this is not the one to get. When I installed mine, I noticed the gauge only updated once every second or so - that's basically zero fidelity while they advertise in a boasting manner with "whole measurement finished in 5ms". While this MAY be true for the analog output (don't know for sure yet), the gauge basically tells you nothing. I mailed Ecotrons on this, as I assumed the software wasn't allowing me to set the Gauge update rate properly, and told me "the update rate of the gauge cannot be changed and is 2Hz". Why you would throw all this sweet sweet fidelity out the window is beyond me, but apparently that's how it is: On my trusty old MTX-L (with relatively bad analog outputs), at least on the gauge itself the update rate is fast enough (like 25Hz or something) that i can see the AFR oscillation due to the lambda control. Tells me everything is working as it should. The ALM Gauge version is unable to display this level of fidelity on the gauge itself. So if you're getting an Ecotrons ALM - best don't bother with the gauge version as it doesn't tell you much. Better to split the fast analog 0-5v out and use an aftermarket gauge or something. Good to know! I'm planning to do an ALM LSU-ADV Board install and split the analog output between my ECU and my Auber Electronics Display which I got bundled in with my Thermocouple. All that said will the analog signal be distorted in any way if I split the signal?
