Thanks for that Adrian, I think the main reason I originally chose DMS was because I am not very experienced in monitoring JB3 or Procede and I did not want to risk the thing throwing any codes. DMS was a safer option for me to keep my warranty however as you pointed out they are very conservative and the gains are not as good as the other mods. Once again thanks for your help!

DMS certainly has a place in the market...it makes sense for some people. But when it comes to maximum performance, Procede is on another level really compared to DMS.

Nice explanation of the dyno numbers, Adrian. Personally, when I look at those charts, the shape of the torque/tractive effort curve is what I'm most interested in. The absolute numbers are pretty meaningless unless you do the rough conversion that you've highlighted. Even then, it's still only a number. The torque curve tells you what you feel in the seat of your pants since torque is directly proportional to acceleration. If you have a flat torque curve, then you feel a constant surge of acceleration. But if you have a peaked torque curve, then you feel a sudden surge of acceleration as boost arrives, followed by an easing in acceleration as torque drops beyond the peak.
And there's lots more to this subject, such as losses in tractive effort caused by tyre pressures (generally higher pressures give better results), and losses due to centrifugal expansion of the tyre diameter at high speed (effectively alters the gearing).

Yes there is alot to dynos. They are best used for back to back comparisons for tuning or mods. This way the many non-linear variable remain as close as possible. It is hard to use them to compare different cars in different places. Expecially since different dyno types give different results. I have used them extensively throughout my work, so have done the research to know how to read dyno curves, but it is a shame most of the people who like to show off their dyno curves on forums do not understand them better. The biggest misconception I see is that of power vs torque. Some people say they would rather tune for torque than power and do not realise that they are the same thing. They really mean they would prefer power at low RPm to power at high RPM. Adrian |

Hi Guys,
This is just a note to let you know that I will be in the US for 3 weeks from this weekend. Therefore I will be unable to send any Procedes to customers during this time. I know Andrew@SouthernBM has 1 in stock also. Therefore if you plan to get a Procede in this time from me, I would have to get it out before the end of this week, or you can wait until I return (Last week of July). Also, In the USA, Shiv is offering a deal to upgrade Procede Rev 1 owners and JB3 owners for a generous price reduction. I have not finalised pricing, but plan to do the same. However I will not be offering the deal where the JB3/Rev 1 patch harness can be updated. I will only offer the reduction on proof of tune, and you can keep and sell you old tune (but it will not be valid for this upgrade price for the new owner). Cheers, Adrian |

Enjoy the trip mate!
On a side note for yourself and the others on the forum. The Procede you installed the other week is running great. Great power, Great Driveability, and no issues with the car..... Quote:

Hi sorry to be a bit dumb. i've just been through the 6 pages of this post... very interesting!
Question......Adrian mentions "decat down pipes and DCI". I assume the down pipes are the same as what we call in WRX terms dump pipes? Is this puely a stock dump pipe with the cat removed and still connected to a stock exhaust, or after market dumb with std exhaust? Secondly what's a DCI? Thanks |

I am also ex-REX... but I still have a WRX as my track car!! Mine is a 98 that is pretty stripped and not much is standard. It is pretty quick at track/motorkhana/drag. Downpipe = dump pipe. In teh N54 there is a dump or down pipe off each turbo. They each have cats in them. In my case I have replaced them with bolton pipes that have no cats and are a bit larger in diameter. My exhaust system is otherwise stock standard and sounds the same as a standard car. DCI = Dual Cone Intake. Basically replacing the standard air box with two cone air filters. To be honest, I think there is not much power in this mod, and I would have gotten similar results with the standard air box and filter. To get 250+ kW ATW in a N54 is really just a matter of the tune (around 50-60kW) and down pipes (10-20kW). After that it gets harder to get every kW, but next mods would be FMIC, Meth, Full exhaust. which would get you another 20-30kW. Cheers, Adrian |

Hi Adrian,
I probably seen you in the NSW Impreza WRX club. Not sure if thats you that drives a "gun metal grey" WRX with plenty of stickers on. Anyway, I have just order a N55 135i. Just wondering if there is something for the N55? Thanks! Ken |

Yes I am in the NSW WRX club. But I have not got a gun metal grey WRX. I used to have a burgundy RS Liberty until late 2008. Now I have a 98 WRX:
I am currently in the USA working on an N55 135I DCT. It is coming.... but not going to give a date yet. I will say that it should be no more than a month or two. Cheers, Adrian |

It is coming. I was working on it over there. I had the pleasure of driving around San Francisco a few days in a 135i N55 DCT, and it is a very nice car. It felt like it had more go stock than my N54 6MT 135I had stock, but maybe the shorter gearing just makes it feel that way. Anyway, we made alot of ground with it, but we still have some challenges so I am not going to quote a release date at this point. I will say that we got the CAN integration working very nicely, so expect similar features to what we are doing on the N54 in terms of dash integration etc.
Cheers, Adrian |

recent version auto tune?
i hear the latest version of the procede automatically tunes the n54?
also, advise from a retailer of the powerchip believes this mod is not a good option for reasons around reliability and safety? i want one! but theyve done a real good sales job on me as to why not! |

The only downside to the procede is that you need to install it yourself. If you live near Adrian then this is not an issue if its power you want then you will never beat a piggyback tune (procede / JB3). I have had an ECU reflash and the gains dont even compare. |

Give me the sales pitch from powerchip... I want to know what they say that is bad. Autotune has been one of the greatest features we have released. Customers cars are running better, and they don't need to work out how to optimise the tune. We have NO reliablity issues ever with several thousand Procedes out there, and cars are running safer and better on average with Autotune. Tell them to show me one car that has reliability issues with a Procede let alone with Autotune which is more safe. You will regret getting the Powerchip... or you may not if you get the Procede!!
