fluke

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???

of course the search feature might have yielded that as it's been discussed here a few times


9.48 seems to be the golden number for me

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