This isn't really supported, but if you want to do some hacks, it will sort of work.
The MAP sensor is a 0-5V sensor, where 0V means 0inHG and 5V means 60inHG. If you program the innovate to output 0V at 0:1 and 5V at 60:1 (which it can do), then the MAP needle will show you AFR, it will just read as inHg, not AFR or Lambda.
SkyView is more flexible and could be set up to do this better.
We never really get asked this since the lead in AvGas will kill an O2 or WBO2 sensor in just a few hours. You need to be running auto gas if you want to try this. For guys with lead in their fuel, EGT gives you almost as much info.
