That's really cool Jon, the A/F gauge fits perfect. Nice job.
Thank you! I'm pretty happy with how all the instrumentation turned out. I have a question for you and the other guys running E85 though. Are the narrow band readings in mV supposed to be same as if it were running E10? My understanding is that O2 mV is in relation to lambda which is the same regardless of fuel. I just have to look for different A/F ratios. Right?
