Can someone tell me if this looks okay?
I have a 2016 BMW 340i xDrive (B58) with a catless downpipe currently running BootMod3 Stage 2 E30 Map.
I'm running ~E30 but not 100% sure of the exact ethanol content without an inline ethanol gauge. Can someone take a peek at these logs and tell me if I'm about to blow this sucker up? To me it looks like it's running a little lean but I'm not sure exactly what an acceptable AFR range is for the B58 engine is. Thanks in advance! https://www.bootmod3.net/log?id=60ca...729b3970aa76f7 |

I highly recommend getting a $15 E85 test kit from Amazon and measuring the actual ethanol content from the pump. From there, you can use an app or do some matrix reduced row echelon form to see how much "E85" and pump you need. I'd target ~E32/E33 to have a little bit of tolerance built-in.
And the log doesn't look bad! Btw, we have a thread dedicated for logs for fellow members to look at. Would recommend posting your future ones there.
