BM3 STAGE 2 ACN 91 OCT logs, knock, and timing off
https://www.bootmod3.net/log?id=5eb6...0b4338a08e2f69
https://www.bootmod3.net/log?id=5eb6...729b7f9e6c2c85 https://www.bootmod3.net/log?id=5eb6...90c60781373b57 https://www.bootmod3.net/log?id=5eb6...729b7f9e6c2c8b I literally could be looking at the lunar landing or logs from my car and truly both of them I have no idea what’s going on, I just installed an FMIC on my 2015 235i and loaded the ACN 91 stage 2 BM3 tune, I went for a drive and the car felt....lackluster, like it was pulling timing, took a few logs and that appears to be the case, along with maybe a knock? At first I was worried I had a boost leak from the intercooler install but that doesn’t appear to be the case I live in Los Angeles and understand the gas here is terrible, previously I was running the regular stage 1 tune and the car felt great, drove a few track days that way too, but knew that when the ACN tune was a single I should do that, recently switched to the ACN tune but since upgraded the charge pipe and FMIC after previously only having catless DP, a few people recommended octane booster? But I feel like that’s avoiding the problem

boost is good
fuel supply is good afr is good timing is struggling to keep up, indicating poor octane in fuel for the tune. 2 knocks = no good MAF air flow seems low, is this stock intake? what intercooler is this? seems inadequate. |
