If you weren't aware, our post-cat o2 sensor is a wide-band. it measures the A/F for the DME.

You're right, my mistake!
I bought a spare upstream a while ago just as precaution. FCP had a really good sale on them a year or two ago.

It was a legit question. If you don't ask you don't learn.

I saw the correction. Thank you all for the lesson on o2 sensors.

Finally dropped down to stage1 91 after getting sick of adding 2.5 gal of E85 every fill up. Log seems OK. It's a pretty weak log but I just wanted to verify timings and no knock. Im surprised the timing arent better.
STOCK (time 2.180) STAGE1-91: (time 0.260) STAGE1-93: (time 0.550) Is there any way to get something like 15PSI target? Sucks to drop from 16 to 14 because the gas sucks here. I'd try an Ethanol map but the only one on BM3 is the Stage2+ E30. Google says its unwise to try that with stock cat. Should I just accept my fate of adding E80 (as tested) to the 93 and using the 93 tune? Is it even a good idea to use E80 since the other 20% is junk gas? |

BM3 has more than just the stage 2+ map or E30... They have stage 2 and probably even stage 1 (not sure about the latter no one ever logs it). Stage 2+ has nothing to do with DP persay, although DP is still required since it is for everything 2 and above, stage 2+ relies on HPFP. That extra 1psi is doing nothing if timing is worse. You need timing to make power. Slightly lower boost with more timing probably makes more power anyways. Also why would you say the non-ethanol portion is "junk gas" - what is that based on? The ethanol maps makes the most power so if you are mixing E85 already you might as well the E30 map appropriate for your mods. |

For the E85, I thought I had read somewhere it was low grade (low octane, low detergent, etc). It seems to make sense if its sold as a budget item to mix 87 or worse instead of 93 and still sell "up to" E85. |

I've never heard that about E85 and the key thing is the ethanol content anyways (and in turn the octane). As long as you know the ethanol content you can mix accordingly and run the ethanol maps. I would also note that some people choose to run maps that "require" a DP without an aftermarket one, but i wouldn't. |

Anyone have experience with BM3 as a beginner? I have a 435i that I'm planning on going stage 2 on. Have been hearing a lot of good stuff about BM3 but I'm kinda new to it.
