NA 370z on e85

Its a fuel alcohol sensor as an ms3 boy u should have just wired up a gm one, it measures the alchol content in the fuel and adjusts both the afr and timing based on that. Without one you are making a rough guess at the octane of the fuel in your tank, trying to ply catch up with the o2 sensors, and praying it doesnt knock. Then again u were only running 25% e85 and u were on an aftermarket ecu with much better closed loop adjustment and more accurate a/f sensors so nothing you learned on that platform is applicable to what the shitbox nissan stuck us with does when you vary the alcohol content in the tank.
