This is a bit of a tangent, but if you have a minute... copy a table using Cobb's software, and paste it into a reply in the thread on RomRaider. I'll let you know (in the RR thread) if I can make it work.

This is an awesome thread that I have certainly gained quite a bit from and its nice to see a tuner who is willing to post some of his maps for us to view and learn from.
Just wondering Jeff, could you post up your AVCS maps? I am curious to see what kind of profile you are running. I am an intermediate-level tuner, I have a good understanding of the basics. A fellow 'expert' tuner and I will be tuning my other buddy's 18G'd '06 WRX and I just wanted to see what I could gain from looking at your AVCS profile, or if you have any input yourself. I have a map I got from someone else running a very similar setup (18G) but I am looking for more input on how we should modify his AVCS profile. On a side note, does the 08 STi have dual AVCS? Thanks, Cheers. Keith |

This is a damn good thread... Jeff you are the man. Thanks for all the info, it's great to look at your tune a little more in depth.

Thanks for the kind words Ben. Aside from boost recovery between shifts, it feels almost as snappy down low on the street as a 20g (well almost...) I can tell you that the ATP35R on our 08 STi exhibits nearly identical boost threshold gear for gear and is even a touch livelier at part throttle/low boost. The Full-Race header/uppipe and dual AVCS definitely do their part. Interesting that the spreadsheet shows power peaking roughly 6000rpm, because on the dyno it peaks at a bit after 7000rpm and the delta from 6000rpm to 7000rpm is roughly 15-20whp.

One small issue I see with this recommendation is that you have not given the ecu enough timing control where it needs it the most. IMO you want to give the ecu the most control in the area's which are more likely to lead to a broken engine. If you are det'ing low down then the same issue may exist higher up where it's more likely to do damage. With your recommended taper of the correction map you have removed most of the control from the ECU. I would rather have more timing removed up top. |

The thing is my IAM never drops so its not really of concern to me. The other side of this is that you will pull 1* (FLKC) or 2* (FBKC) for 1 knock event at high rpm.....so if you have 3 knock events at high rpm you can pull 6* pretty easily. I went out about 2 months ago and logged my old room mates 04 STi with Cobb stage2 OTS map and he was pulling 4-6* via FBKC from 4000rpm to redline.....so just because your DA map has small values at high rpm doesnt mean you're never gonna pull more than 1* up there. I'd bet money that if you started running really lean (12-12.5:1) due to a leak that you would need to pull more than 1* of timing at redline. Well, i'm not really sure what you mean by lumps....but a stock Total Timing map isnt exactly smooth either. And most tuners and most OTS maps dont touch the timing at low loads.

The utility I linked to earlier makes it very easy to see the shapes of the base, advance, and total timing, and it makes it easy to edit the tables. For example you can edit the advance table without changing total timing, and you can edit total timing without changing the advance table. Most customers wouldn't notice, and therefore wouldn't care about, changes in low-load timing. So of course nobody is going to spend their valuable time modifying that stuff. I'm not sure what you're getting at with that last sentence? Last edited by NSFW; 02-25-2009 at 01:05 PM. |

the stock maps have plateaus in several knock prone spots (1 where the avcs is shutting off and 1 where the per cylinder timing compensations are turning off). The plateaus cause the timing curves to appear lumpy. IMO, the subaru tuners knew what they were doing. The timing maps have to look like that for a reason. |

2nd gear went to well over 7k, but third only went to 6300 rpm. 3rd would show it better, as there is better resolution. Send me a third gear log til 8k and I bet it will look pretty close to the dyno. FWIW how close are the graphs (delta %) vs your dyno-jet? 6-9% off? |

For those that dont use these tools, here's what we're talking about.
Here is a total timing plot done by a shop that posts in PPB. The rom was sent to me by the customer. Here is one of mine, not saying its right....buts its pretty |

Boy, it took me a while to wrap my head around those graphs but once I turned my head sideways it all came together.

The most annoying thing about RomRaider is the way it shows tables. Origin in the upper-left? RPM on the vertical axis? If someone writes a tuning app that puts RPM on the horizontal axis and the origin in the lower left, as god intended, I'll switch in a heartbeat.

^^ ?? im lost. every ecu/program i've ever used (AP,ecutek,romraider, ecuflash, UTEC) show the tables the exact same way.
Or did you mean the way Excel shows the tables, not romraider? Those timing graphs I posted are from excel, not romraider. |

I guess it's only a matter of time before dyno plots start showing up with RPM on the vertical axis (0 at the top, redline at the bottom) and horsepower on the horizontal. |
