Bootmod3 datalog review?
I recently installed Stage 1 91 Octane on my 2014 435xi with almost 140k km's. I noticed some knock in the data logs but I'm not an expert at reading data logs and was hoping to get some feedback from you guys
Currently, I have an ER catless downpipe on the car with a VRSF charge pipe and I'm running Petro Canada 94 octane gas This one is a dig from 1st to the top of 4th I think (I had to let off the throttle or I was going to rear-end a bus lol) https://www.bootmod3.net/log?id=60d3...729b06dfeb5e10 These 3 are 3rd gear 2500-6500. I apologize for the length of the last one, I forgot to stop logging but the pull is at the beginning. https://www.bootmod3.net/log?id=60d3...729b0660b5b094 https://www.bootmod3.net/log?id=60d3...0b437f45452060 https://www.bootmod3.net/log?id=60d3...0b437f45452061 Based on these logs, would it be a good idea for me to move to Stage 1 93 Octane and eventually Stage 2? For any people from Toronto. Can Petro 94 gas support the 93 octane tune? Last edited by ODX7; 06-23-2021 at 06:52 PM.. |

You need to collect "proper" datalogs. Please read my thread, relog, and report back.
https://f30.bimmerpost.com/forums/sh....php?t=1732327 Oh, and get an IC before you do anything else... Even for stage 1. |

and fyi, knock events under regular driving are normal for the most part because of low rpm high load scenarios. don't worry about that.

After you install an IC, it looks like your fuel quality may be sufficient to run the 93 map, but of course relog after switching to confirm. You will also need to watch it when you switch to stage 2 since timing will be impacted by the higher boost, even if you keep IATs under control. |

Tons of threads on this. You are just going to start a debate if you ask here. Just read through one of the many IC threads in this section and pick one. There's also some new/cheaper options out from XPH that haven't really been tested yet.
