Your wideband does not output a signal that the factory ECU can translate. The wideband 0-5v output is for piggy backs and standalones.

That's a bit disappointing.

What is your BSFC ??? I don't think that should be possible. Not on Earth anyway!

The rear o2 can take the 0-5v input and log it, but I believe you lose a lot of resolution in the ecu since it only logs tenths of volts not hundredths.

100% duty cycle on 440s with e85 is a little over 250 crank soo not that big of a deal. Still probably under 200 wheel hp.

I got two websites that show 230 crank, and one showing 258. And that's being on the safe side of 90% DC. TIL you can still max out big injectors NA.

The ECU expects 0-0.9v from the rear O2, not 0-5. The ECU only sees three things from our O2 sensors. "Right" "wrong low" and "wrong high" and it adjusts accordingly.

So I'm just getting started tuning my 2.0N/A. I read that around 12.5-13:1 AFR is best for torque, so I was thinking about playing with the power-fueling map. Is it okay to make widespread changes to the map? What do your maps look like? I guess I'm a little scared to make big changes haha.
Thanks for the help.

Btw, for a good time, call 1-976-open-loop. She's hot and waiting for you, studly.

Be sure to set your closed loop warm-up setting to 205C before you call .
