2) if you're running E85 with a proper kit for it (requires stronger/better lines) i would recommend having a tune as you have the ability to run more power with it

11-11.5:1 under load, the bit of extra fuel helps cool the combustion chamber and help with knock prevention. |

Looks fine to me. Near that 4K mark is where AFR tends to target lower, 12.2 or lower depending on tune.
But based on the trims I can tell there is still E85 in there. And why the ignition is so choppy, I don't know. Need more data. Probably DTC kicking it. You need to do logs with traction full off, and a solid 3rd gear, from 3K to redline would be nice. |

Here is one I just pulled. I'm flash only, MHD E60 map; MHD version 1.66 IJE0S v7.1 E60AT_ALP
You can see it's about the same trend, near that 4K mark it starts to richen up. |

I think everything looks really solid.
The only thing I don't know what it is is "Trims". It's a JB thing that I'm just not familiar with. But the fueling, boost and spark stuff looks nice. AFR is trending down just like it should, Spark going up with RPM. Boost looks really solid up to redline. I bet the car feels really smooth? |
