Post up your WOT logs!
Hey all.
Just because I'm fascinated with tuning, I like to look at other people's WOT logs and compare them against other ones and assess the information. Also, I'm getting bored with my own logs. So, if you would indulge me, let's have a look. State the following to accompany the files. -Vehicle year, make, and model -Manual or Automatic transmission. -Power upgrades -Gear used to capture datalog Please indicate if the run was performed on a flat straightaway rather than an incline as I or someone else can post a Virtual Dyno graph. If you want, let me know and I can run your logs through the Airboy's Dyno as well. Make sure at least the following is logged; engine speed, boost, MAFv, MAF g/s, throttle position, load. If not, then post whatever you have. We still like to see it. To create a graph, all that's REQUIRED is throttle position and engine speed. On another note, please do not post WOT datalogs from an UNFINISHED protune (etune). As has been exemplified, there's different methods different tuners use to arrive at an optimal tune. Observing these logs and stating opinions based off them can create a conflict of information during the tuning process and that's confusing. Only post logs after your tuner has finished with your vehicle. If you are a self tuner, feel free to post all the WOT logs you want and we can see if we can help you arrive at a proper tune. Also, let us all keep this on the topic of posting WOT logs and brief commentary therein. If you have further inquiries, feel free to PM me. I will do what I can to help. Understand, however, I am no professional. I am a self tuner that's learned from professionals much more capable than me, lots of reading on the subject, and countless hours of seat time actively tuning. I have much more to learn and that's the motivation behind this thread. It'll help my experience and hopefully educate the community in the process. Thanks.

Hi Joe,
I'm getting my car E-Tuned right now. Here's my setup. 08 WRX - MT, logged in 3rd gear, pump gas 91 octane - FP71HTA with IWG - ID 1000cc - DW65C - FMS FMIC - COBB 3-port EBCS - AEM Intake - Invidia TBE - HKS SSQV - COBB AP V3 and Tactrix OP 2.0 Here's my 3rd gear WOT log https://docs.google.com/spreadsheets...it?usp=sharing Please run my log through the dynos.. I want to see what kind of power I'm making right now.. thank you Last edited by RC0310; 11-23-2015 at 04:36 PM. |

Try Virtual Dyno - I estimated 200 pounds...
Tune feedback - * MAF needs to be rescaled - you maxed it out at 300 g/s * Too rich during spool (10.0, could be lower..) * FLKC at higher RPMs * Higher RPMS AFR is quite lean (11.7) Not sure what your boost goal is but looks like your tune will improve a lot. For example my VF52 (92 Pump, Stage 2 +ELH) took about 4.62 seconds to go from 50 to 90 MPH. Mapping RPMs to MPH looks like you car did this in 4.98 seconds. |

Thanks for your reply. Where do I get Virtual Dyno?
I just received revision 3 today. I'll datalog it and share with you guys soon. Quote:

Hey, you're stealing my thunder! I wanted to do that.
Anyway, it's obvious to see that this tune is incomplete so I don't need to comment on what I see. Virtual Dyno is a great tool to use and it's fun and easy. The Airboy spreadsheet is not as user friendly, but has so many more features to assist when tuning. It's been my experience that the Airboy plot generally reads slightly lower power ratings than the VD plot. Your log was no exception as you can see. Nevertheless, the curve between the 2 is virtually identical. This just shows that ALL dynos, whether software types like these or chassis dynos, are tuning tools first. What's really important is increases/decreases observed with each respective change. The actual numbers observed will vary from dyno to dyno especially when you throw changes in atmospheric pressure and temperature. Thank you for posting your log and please post a log of each revision. If possible, let me know WHAT the tuner has changed also. |

hey guys,
just made a video of my 3rd gear WOT run on my Revision 3 E-Tune last night. https://www.youtube.com/watch?v=27BpeioHbow Here's the datalog. https://docs.google.com/spreadsheets...it?usp=sharing I forgot to datalog with my RomRaider/AEM wideband.. I'll do that for Revision 4 Please give me some feedback on how my tune is running and what needs adjusting. It seems like the target boost is now 19 psi.. (I don't know why my accessport logged in kPa instead of psi..) |

Different tuners have different styles of tuning. In your case it looks like he started with a base map with the timing he wants to run, lowered boost to 3/4 of the max he plans to run and then set fueling to run very very rich so that he can scale the open-loop portion of the maf (because the unscaled maf will probably make you run lean and your log shows that as well but it wasn't too bad). In your revision 3 he lowered timing to correct for the knocking and brought fueling and boost closer to the intended levels. The next few revisions will probably be tweaking boost response and/or playing with fueling, boost, and timing to try and safely make a bit more power. (At least thats what I'd do) Last edited by ShinjiML; 11-25-2015 at 03:04 PM. |

Here's the VD of the second log overlaying the first. As you can see, power dipped slightly, but torque jumped some most likely fire to the increase in boost. A lot of things may be a factor. Road incline, temperature, pressure, etc. The Airboy plot agrees.
I'll look over the logs but it's challenging to compare the two. |

Here's revision 3 datalogged using RomRaider w/AEM.
https://docs.google.com/spreadsheets...it?usp=sharing should be receiving Revision 4 tomorrow.. thanks for all the feedback guys. Trying to learn as much about tuning as I can. |

Your under boosting significantly, start to look for leaks, check you AF learning 1 A, 1B, 1C, 1D.

What he said. The graph below shows it iis affecting power output.

He's definitely smoothing things out and getting closer. Still running a little rich but that's okay. I'm curious why the log shows the dip in boost. That's strange that it drops and then recovers. That might be something to look into. |

Also the dip in the boost is weird...wonder if he made a typo while modifying the wastegate or boost table... Also hope he'll turn the boost up to 20-21 psi on that turbo. |

thanks for the feedback guys.
what do you guys think about water/meth injection? There's only 2 places locally where I can get E85 and it's a 1 hour drive to get there. I'm not sure if the tuner would raise the boost anymore since I'm just running on 91 octane pump gas. I'm pretty happy with the power right now and don't really need much power than this on the streets. what other mods would help me gain a little more power? as you can see, my car is a budget build. Happy Thanksgiving to you all! |

Water/Meth injection with 91 octane will allow you to run closer to a 93 octane tune. EL headers also help a lot with 91 octane. |

Note if you rename the 'A/F Sensor #1 (AFR)' parameter to say 'A/F Sensor #1 (A F R)' then VD will show the true AFR once the boost kicks in. The factory AFR sensor doesn't read correct, thus the super flat 11.14 AFR .
Try logging target boost - AFRs still seem to swing a bunch, from 11.1-> 10.2. and same with Mass Air Flow (g/s) post 5700 RPM. It should slowly increase and not have drops?? |

Also the AFR really is choppy, not sure if the tuner is trying for a "rich spool"...but I don't think it really works or makes a noticeable difference to warrant the extra effort. Last edited by ShinjiML; 11-27-2015 at 05:18 PM. |

just wondering if there was any way my map could be set to 15psi while still showing a boost error of 17psi. this is a custom dyno tune from a fairly new tuner and i told them to tune conservatively. unfortunately i was foolish enough not to log after the tune. trying to figure out if its mechanical or tune issue... car seems fine except there is a slight studder after goin into 4th under light throttle. otherwise runs well.
