Look forward to the finished product tho. Nice work

That's interesting...
On my G37, during low to mid engine load the AFR is typically around 14.7 - 15.0, full throttle is low 12s and off throttle is 20+. As I understand it, those are expected values.

But I don't have anything to compare it to.

Anyways, I will keep that in mind and try to find someone local that has a standalone wideband.
