335i EWG Pulling Timing
I have a FBO 335i EWG. Charge, boost, 5" FMIC, DV+, Catless DP. I have replaced spark coils and I replaced Bosch spark plugs with Bosch spark plugs gapped at .03. The timing is all over the place and I think I'm getting micro-knock.
Would NGK 2 step colder @ .024 - .022 would solve my issues? Also is 0.1/0.2 knock a micro knock? I didn't do WOT because it's already pulling timing in regular driving. Any advice is welcome. Stage 2 - 93 https://www.bootmod3.net/log?id=5fb8...0b43791b7e80c0 https://www.bootmod3.net/log?id=5fb8...0b4379a0d81037 https://www.bootmod3.net/log?id=5fb8...729b32856eb2d4 Stage 2 - 91 https://www.bootmod3.net/log?id=5fbe...90c61927713bab https://www.bootmod3.net/log?id=5fbe...90c61897db89c6 Thanks

so get the thought of something being wrong out of your head and move on to WoT runs and let's take a look then.

https://f30.bimmerpost.com/forums/sh....php?t=1732327 Give it a good read through, maybe twice, then come back with 1-3 WOT pulls in 3rd/4th gear as described there. |

Just a follow up. I got NGK 2 step colder plugs put in (.024 gap). They resolved my issues.
Here's a log Stage 1 91 Octane Bootmod https://www.bootmod3.net/log?id=608d...729b364fde9c87

I'm not saying they can't make a difference, but want to understand why you think the plug change was responisble for what you are seeing, since most people dont need or even want to use those plugs and a smaller gap, especially on stage 1. |

I'm glad you arent getting knock just not sure how you can conclude the plug change was the reason when there appears to be several other variables lol. |

Also I read thru the forums and nobody mentions microknock and what 0.1 knock means. I'm guessing it's microknock. That's why I'm posting my experiences hope it helps someone. BM Stage 1 93 Octane tune 4th gear pull today: https://www.bootmod3.net/log?id=6095...729b602cd333d2

It's a daily with no knock or 0.1 knock or anything. I'm ok with little pull, I don't track it or do OWT over 1 second since I'm mostly driving at 30 PMH in the city(NYC) or cruising. I don't see a big deal with stage 1. Once I put in a better cat like the Wagner Sport pipe with cat and do stage 2 again, then I will revisit the issue if it comes up. Thanks for all the help guys. Much appreciated.
