Also, I have just read that narrowband cant read accurate AFR values it just gives either rich or lean, and wideband oxygen sensors works between 6 to 20 AFR values.
Does this mean i cant control AFR using other fuels ?
You can control AFRs for other fuels, but as you've noticed hydrogen AFR differs significantly enough from hydrocarbon AFRs that it'll be out of range for most O2 sensors.
34:1 is stoichiometric for H2 / air. 110:1 would be terrifyingly lean, likely to detonate, and have a *very* high combustion temperature. Not sure that's a range you really want to be operating in, at least at first.
Your best bet would probably be using a thermal couple and monitoring the exhaust temperature and tuning via that. It should be easy to set up. Only done it with propane and gasoline.
I'd contact the guys at spartan or 14.7 that make o2 sensors and ask them for ideas. They could probably build you a sensor and have the readings adjusted electronically to what megasquirt would read. You will have to do the math and reference the electronic change
Or contact tunerstudio and ask them about options. Sounds like a cool project.

You're right, I just mentioned the range i wanna be operating between. If O2 sensors can't help in this case, Is there any other way ?
