Bootmod3 Canada gas
For all the bootmod3 guys here. What gas and maps are you guys using. I'm using stage 2 91 octane with shell 91 & sent a data log to PTF. They said my gas is really bad. They are suggesting trying Petro 94 with stage 2 93 flash or trying the stage 2 ACN91 map with shell 91. FBO M235i here. Curious what you guys are having success with.

Can you post your log that you sent them?
Their suggestion sounds reasonable. If you have access to 94 why not run it all the time? Is there a substantial price difference or limited access? |

^^^^ this is the log I sent them. And the main reason is I have 91 gas stations all around me and the only petro 94 access I have is quite a hassle to get too. Especially for every time I fill the car. |

Timing isnt great in the log, but its also not totally horrible. It would probably be better on the ACN map though as they said. I would say go out and get 2 "proper" logs, evaluate the timing, and go from there. Their recommendations is definitely the 'safest' way to go though. |

Here is another data log I don't recall which had a better pull this or the previous one. https://www.bootmod3.net/log?id=5ee9...90c62a22b5a132 Honestly I'm not concerned at all about the little bit of extra power for the 93 tune. I just want what's 'safest' for my engine. That's all that I'm concerned for. Whatever that takes I will do. Would you recommenced the acn 91 stage 2 or the 93 stage 2? Also I'm located about an hour north of Toronto Ontario. Transmission is 6mt rwd |

If you are going to run 91 pump gas, in theory the ACN is the "safest" because its going to target the lowest timing. But the DME is very good at pulling timing so its not like running the 91 tune is going to instantly blow your engine, but again its always safer to run a more conservative timing map if fuel quality is an issue. We have no data to know whether or not you could run the 93 map with 94 gas or not. You would need to run your tank to nearly empty, fill up with 94, flash the 93 map, drive for a bit, then do a few logs on that map to see how timing looks. But if you dont want to go through the hassle of getting 94 all the time, that might be a moot point. |

What are the N20 plugs? The NGKs? I just don't think they prioritize the ACN tune since its sort of a "on request" tune and not widely used. If they say its safe... it should be fine lol. |

I dont want to thread hijack. But I am in almost the same boat with bad gas here in Canada. I am running the ACN91 tune from BM3 on my stock 435i and I am having the same issues. I have been talking with PTF about what we can do, as using even shell 91 here is terrible. I recently filled up about half a tank with some chevron 94 and here are my logs I tried today:
https://www.bootmod3.net/log?id=5eef...729b70aebc190a It was only in 3rd gear as I couldn't find any place nearby that I could run 4th gear out. I am hoping to maybe try mixing a bit of E85 this week as we have a single station here that sells it, but I am waiting to hear back from PTF to see what they say. |

Did you add the half tank of 94 to half a tank of 91? Or was this all 94? E85 is a great option if you have it. It's also worth getting one of the test kits to test your E85 content so you know how much to mix, especially if you plan to do it long term. I ordered the fuel-it one on amazon. Its just a little glass jar you use (i.e., not a sensor you wire in). Also, gonna put a plug for my new datalogging thread incase you want to learn https://f30.bimmerpost.com/forums/sh....php?t=1732327 |

This was done with half a tank of 94. im going to try and refill later with all 94 once this tank is empty. Then depending on those results, I will go get some e85 and try some mixing.
Thanks for the heads up on testing E85. ill make sure to get one. Also funny enough I was just reading the thread on how to read logs this morning . As for blending E85, is there a good guideline on how much to fill? This car is my DD so im not sure if I want to try amd mix for E30 all the time. Maybe just help it to run the regular 91 or 93 tune. I will see if I can find a good place to do some 4th gear pulls. I think ill just need to drive little ways out of town and find a quiet road to go that fast on. |

The only drawback to adding ethanol into a pump gas map is your fueling will be off (lower energy density of ethanol) so you need to watch your STFTs. |

Shell 91 is horrible sadly in our area I stay faaar away from it. Chev 94 has proven to be consistent. All my logs are too old too post so I will grab some next time I'm out on a cruise.

Well I just filled up with chevron 94 and did a 3rd gear pull. Results were....not great. Thought there still is a bit of 91 in there. I did fill it with 50L of 94 so well see if I fill up another tank and get some more logs in this tank. Makes tuning so disappointing when our fuel is this bad. My only saving grace is I might be able to get some E85. Though I might be moving to Edmonton in a few months so not sure if ill be able to get anymore of that out there.
Here is my 50L of Chevron 94 with Shell 91 previously in there log: https://www.bootmod3.net/log?id=5ef8...90c61189c02c80 |

How much 91 was left and how far did you drive after filling up? At least a few miles to get the new fuel mixed and to the engine? Try to run nearly empty and add the 94. EDIT: Also, how many miles on plugs and what gap? |

I put in about 50L of 94 which should have left me with about 10L of 91. I did drive for about 10 mins to mix the fuel. I'll give it a shot later this week and then try and get the tank lower to completely remove as much of the 91 as I can.
I have about 44,000kms on the car and I don't think the plugs have been replaced. Unless it was part of the regular maintenance up to this point, I have not touched them. So I cant say I know what the gap might be. Do you think changing the gap or replacing the plugs would help at all? |

Spark plugs don't really make a big difference. I'm surprised the ACN91 map is this bad. If you can't find ethanol you might need to get boostane. Have you tried Petro Ultra94?
