Megatune isn't reading my wideband AFR correctly after hi res
Before I went to hi-res (was running 29_ before) megatune showed the same AFR as my AEM gauge (it's an AEM linear). After upgrading to hi-res it's now reading ~ .3 AFR lower than the gauge. Anyone know why this might be?
Also, I looked into the equation in Megatune configurator and it looks funny: AFR = 9.72 + egoADC * 0.038666 which is strange, according to AEM the end points are: AFR 10.0 at 0V, AFR 19.98 at 5V I thought the equation should be: AFR = 10.0 + egoADC(V)*(1.996) Is the equation in Megasquirt Configurator wrong??? |
you might be on to something...

I did search and couldn't find anything, thanks for your help!
