Setting hotwire CO
Posted: Sat Aug 28, 2021 10:45 am
Hi
I killed off the original AM5 Mass Air Flow Meter and have replaced it with a Britpart one. Prior to fitting I checked the voltage & found it to be 1.89vdc , I retrimmed this to 1.8 vdc(for a catalysed engine) as per the write up - went for a spin to warm everything up and then measured the CO , this was reading around 0.1 -0.2 %.
The Landrover Engine Manual states this should be 0.5 -1% but dosnt say if that's with or without catalysts ?
Can anyone enlighten me
