LEMv5 Closed tuning via Wideband Input

Recommended Posts


Like the new site btw, good forums, and prof. looking site.

I'm using an LEMv5 with an Innovate LC-1, using the wideband input on the LEM configured as per Link manual, and its tuning just great.

I'm just wondering if when Lambda is switched on, is the wideband afr used as an input?  Or does it have to be narrow? (I haven't bothered to hook this up).

With Lambda on, the ecu does adjust zones, but doesn't seem to get very close to the set target.

The LEM can only do dither based off the narrow band sensor

Dither is only active at idle and cruise the aim of dither is to allow a small correction to keep the afr's at stoich under these conditions
