I never bothered with data logging because my car has been running smoothly for the past year on the OTS Sport Stage 1 maps. But now, all the buzz about the amazing properties of mixing E85 got me to want to give Aggressive a shot (as I do not have access to 93 here in Cali). |

Use the default logging channels and be sure to have STFT and LTFT marked as logging channels. |

Sorry I wasn't used to the format you have it in. The car seems to be running fine to me. It's definitley hot where your at and I believe thats why your only seeing 2 max degrees of timing where I'm sure agressive should be around 4, but no timing drops which is good.

So pretty much if I want any real gains with e85 I need to stick with procede or jb4, until Cobb comes out with dedicated e85 maps?

I'm waiting to empty this tank and I'll get some logs of 50:50. Meth helps to reduce fuel trims 👏

Ahh, I completely over looked the HFS-4 in your sig. Meth just may have to be our saving grace until Cobb releases those fuel scaler tables. I'm contemplating a 50/50 93-e85 dyno tune....

You want the fuel trims to be well below 34%(Max fueling.) Most people(including me) want to see low 20s.
Save a copy of the csv as a txt and then post it up as an attachment and I'll go through the log with you. |

Would love anyones thoughts on this log. Timing is being pulled on one cylinder. Ill check the basics, new plug and swap the coil.
I will relog to verify the one cylinder is the culpret. Anyone see anything else odd? ...and i will turn on the fuel trims for next log. Anything else i should do? |

Map has been installed for a day, with a handful (5-10) WOT pulls done, so adaptations should be set. I started logging at a stop light, and did a 2nd & 3rd gear pull. Would you please check if I'm running safely with this map & mixture. |

Aside from the timing corrections in no.4 everything else looks good. |

Timing corrections don't necessarily mean you have too aggressive of a map. If you are seeing multiple cylinders getting corrections together then its what we look for but little random corrections are typically just noise. The sensors here are too sensitive and you should learn to weed through the "noise" and find the actual events.

-You only logged timing corrections on cylinders 1&2 so i can't say for SURE you didn't thave any timing corrections, but you didn't on the 2 that you logged. -No Throttle closures -You're within 10 points of hitting load targets(normal) -AFRs are solid -Fuel trims are good. STFTs(which is most important) spiked at ~28% but recovered quickly back into the low 20's and then continued trending down Looks great, especially for running an aggressive map on ACN. e85 is a wonderful thing. Keep the mix as you have it now and you should have no problems. Keep in mind that on e85 you may occasionaly trigger a "fuel mixture" code. It's not a problem and does nothing to affect performance. |

Based on what he posted in the log it looks like it may be something mechanical(plug, coil, injector) if it is always on that cylinder. NO.4 was making a couple corrections at a time while the otheres were silent. |

I figure from now on, ill run the Sport ACN91 on the weekdays and on the weekends fill up with an E85/91 mix for fun. What variables do you recommend I remove to allow room for the other 4 cylinders read-outs. I tried selecting all 6, but unfortunately I've found the AP can only log a handful of variables at a time. Very much appreciated! Cheers! |
