'07 STI - SPT Cat Back only with Ecutek Tune vs stock
Here is another car which I really enjoed road tuning after the dyno session - what a real smooth and great running car the '07 STI is - hard to imagine that this is the last of the great WRX 4 doors
I put two arrows on the sheet to highlight here the car was having a delay switching to open loop operation with the stock map and you can see the coreponding roughness in the stock tune due to the ultra lean a/f which the delay period causes. With my tune, I accelerate the transition to open loop and I also smooth out the timing map and work the avcs to get a lot more low end power.

That looks better than the previous car Al. Just curious, why do you start your pulls past 3k RPM? I understand doing this with a big turbo car but the stock turbo hits full boost right around 3k RPM so don't you want to showcase the spool characteristics of your tune as well? There's also still a bit of "roughness" as you call it present in your tune in the 3500-4k RPM region. I find this area to be a bit tricky to smooth out with the 07's as well. I believe this has to do with the higher compression and generally takes a some AVCS and ignition advance work to smooth out nicely and alleviate any knock.
BTW, how much boost are you running on this car? Thanks -- Ed |

Peanut Gallery? People are commenting on the vehicle that he has tuned and the issue they see with it. What? No one can give there opinion on why the tune has an issue yet again? It is pretty funny. Especially since again, only a day later and another car has the same dip. I dont think it has to do with anything to do with bashing or being very nice. It common sense. |

Ed, got any other insight on this? As for the closed loop delay, that's nothing new and is even more evident why the 07's need to be tuned when you start to throw after market parts on them. - Chris |

I appreciate your comments with regard to the '07 which is without a doubt one of the most difficult to master stock ecus I have ever had to wrap my head about. Of course - aside from the obvious power delivery tuning the stock ROM has several rough spots and a significant hesitation between shifts all of which took me a lot of time to resolve. I agree with you in that the key to a good result with an 07 is to work with the ultra senstive knock reaction of the stock ECU and map the ecu in a way to minimize any knock events. I have found that the best way to get a good result is with very conservative tuning. I also agree on the SPT cat back - our ICS SHOP STI was making virtually the same power with a 100% stock exhuast. This customer's objective was to try and get some more power and stay as warranty friendly as possibel. Al |

Ed - I look for and alieviate knock with my data logs and by watching what the ecu and sesnors are recording. No car leaves my hands unless the data logs both on the dyno and also in a subsequent road test show a total absense of knock reponse in the ecu and also unless the car is mapped with zero knock what so ever. The main thrust of the DYNO comparision (as specifically opposed to a dyno like simulation software) is to show a A - B comparision between the initial factory tune and the post tuning Ecutek tune which I did I do the runs the same way before - RUN A and the same way at the end RUN B - then you can see how the car responded to the tuning and quantify any gains or losses which have occured as a direct result of the tuning. I will point out that in most cases this kind of tuning gives a huge advantage to the stock tune for several reasons 1 - In most cases when the car come sin with the stock tune the advance multiplier is all the way as high as its going with the fuel in the car 2 - When the car comes in the tmic is usualy cool or at least not heat soaked. 3 - By the time I do 15 or so dyno pulls tuning the car the tmic is usually very heat soaked and also the engine itself is usually very hot. Despite these factors it is clear that the tuning makes significant gains in power throught the power band. In addition - the stock rom hesitation issues and inter shift hesitation are all totally resolved. Al |

XX is over 80 miles from my facility at ICS
By Region, I mean Fairfield County and the NY metro area with over 13,000 square feet - 13 lifts - two alignment racks and a seperate dyno cell with its own lift - I think ICS Performance has more than enough resources to tackle any service needs that my customers may have AL |

When you work for yorself as I do its hard to fire yourself - although I may get mad enough one day to do that
Actually, I left my old facility on good terms - I have nothing bad to say abot them what so ever - I just found a facility closer to my home (within a mile) which better suited my needs so I decided to take my dyno leasing needs there There is no need for all this drama and nonsense Thanks |

I sincerely hope that we do not need to get into a my penis is bigger than yours type contest
If need be we can get out a tape measure and calculate the size of every shop you wish to compare Honestly, I have more important ways to spend my time than arguing |

Please - all this OFF TOPIC bickering MUST STOP
If you are not discusing a technical aspect related to ecutek - tuning - the dyno sheet or car please just refrain from posting it and stay out This is a tech section not a soap opera forum AL |
