lesgrandepotato Posted January 29 Report Share Posted January 29 I’m fitting this into my Samurai with a link Atom X ECU. I’ve sorted most of it. But I’m struggling with the one wire lambda sensor… Do I have a to build a circuit? Do I need to buy and fit a wide band? Does it go in the same location at the end if the 4 branch manifold?

Vaughan Posted January 29 Report Share Posted January 29 Narrowband O2 sensors can be connected directly to an An Volt input but they don't really provide any useful tuning information. I would highly recommend fitting a wideband (which requires it's own controller) and preferably one that has a CAN output as this provides more accurate values to the ECU.

Ok, so as I understand this, we can tune the car on the rolling road and it’ll be fine and run safe. But the drive ability and performance could be improved if we run a wide band to allow the ECU to self trim? Quote Link to comment Share on other sites More sharing options...

Assuming the tuner has his own wideband. 3 hours ago, lesgrandepotato said: But the drive ability and performance could be improved if we run a wide band to allow the ECU to self trim? Even if you dont use closed loop it is valuable to have an air-fuel ratio measurement to diagnose and fine-tune areas. Quote Link to comment Share on other sites More sharing options...
