How Can I improve timing?
Hello,
I'm looking for some feedback from people that do tuning/engine.N55 2014 54k miles How can I improve timing? Or is my engine isn't good? I have VRSF 5" HD IC, FTP downpipe & lower pipe, GFB BFV, Dinan Spark Coils, NGK 2 step colder spark plugs(.024gap), k&N filter. (AA DP coming tomorrow) I'm running BM3 Stage 1 93 https://www.bootmod3.net/log?id=6445...729b8fabdb786e https://www.bootmod3.net/log?id=6445...729b928e690f7a https://www.bootmod3.net/log?id=6445...90c6650af7c0bb

You can change back to the OEM plugs to start. No need for colder plugs on your tune. Especially not 2 steps colder.
Generally speaking, for best combustion you want the hottest plug that can be safely run, and the widest gap (largest spark). So, oem plug, oem gap. The “must run colder plug” thing is dying out, but I still see people outside this forum recommending it too often. |

It has nothing to do with plugs unless they need to be replaced. You may just need better fuel. Try the 91 map and see if that's it.
What downpipe do you have?

I currently have stock DP. I will be putting in ACTIVE AUTOWERKE GESI Cat DP tomorrow. I'm going to flash to BM3 Stage 2 MultiMap. I've been using Shell 93.

I wish I can find E85 in NY or NJ that easy.

I'll try different gas stations. Just quick update, I have the AA catted DP installed(should've done it sooner) and I'm running BM3 Stage 2 Multimap, Map 2(Stage 2 91). It's currently raining so I couldn't do pulls. Butt dyno feels good.
I don't think you can tell much from this log. I'll log once it's dry. https://www.bootmod3.net/log?id=644d...0b434d4e39e371

Are the logs with traction/dsc off?

No they are not. I didn't know traction would pull timing.
I managed to find E85 at a Sunoco by the airport. Full tank Sunoco 93 & 1 Gallon E85. Multimap Stage 2(91 Octane map) I couldn't get the RPMs to 6k because I wasn't doing the runs on a fast highway. https://www.bootmod3.net/log?id=6457...0b4301999f0705 https://www.bootmod3.net/log?id=6457...0b43fe22c11b82 https://www.bootmod3.net/log?id=6457...729bbccd0fe58c https://www.bootmod3.net/log?id=6457...90c6174874592b https://www.bootmod3.net/log?id=6457...90c61b6bf1d3c1

It's hard to tell anything from those logs but i dont see to much timing during the short WOT... need better logs though, log only the pull and go higher RPM

I got some logs. I was running Stage 2 Multimap (91 Octane). Traction and DSC off.
I have put in 1 gallon of E85 drove around and put in 2 more gallons of BP 93. Based on these logs I'm thinking of re-gapping the spark plugs from .024 to .022. https://www.bootmod3.net/log?id=6460...90c63403eb7b00 https://www.bootmod3.net/log?id=6460...90c63403eb7afc

Had the same problem with bad timing all you need is a 2-3 of e85 when you fill up with 93.
This are two logs of stage 2 93 first one with no added e85 and the second with 3 gallons of e85 added. 1. https://bootmod3.net/log?id=64594f71d10b43fe22c1246d 2. https://bootmod3.net/log?id=645bf340d10b438bce76b2cf |

Mixing E85 - all that hassle for running the 93 map... On the 93 map you gain something like 15hp over 91. You genuinely cannot feel the difference
SlumpLord3000 Factory plugs at factory gap. Have you tried? ONLY gap if you have problems with factory gap. Gapping your plugs will negatively impact performance if not needed.

I do it mostly bc the e85 station is only a couple minutes from my house. But I’m waiting for it to get warmer out in NY before I switch to the stage 2 e30 tune for the summer. Usually add 4-5 gallons of e85 for that tune.

Do you have an up graded HPFP for the e30 tune?
