Hi All,

I installed a meth kit on a car a couple of weekends back and we hit the dyno with it last night (attached). The car is an 08 135I 6AT with following mods:

* Procede V4 latest maps
* DCI
* Full exhaust with decat down pipes
* Vishnu Meth Kit (75/25 meth/water)

The lowest run (199kW ATW) is in valet mode which basically puts the tune to standard, but it will make more power than standard because of the other mods. Typically a stock car is around 175-185kW ATW on this dyno, but the mechanical mods made it quite healthy.

The middle run is Procede map 1 without meth, which is 13.5psi. A nice healthy 239kW ATW which is pretty much as expected for a 6AT with Procede and other mods. We could have gotten more by putting in a little more boost (probably about 250 with 14.5psi).

The highest run is with meth enabled. The Autotune is running around 15.5psi. The result is an extra 40kW for only 2psi more boost which is a phenomenal result. Meth is fantastic stuff. Normally at this boost we would only be expecting an extra 15kW or so, but the meth cools things down and controls knock to give MUCH more.

I was very happy with this result. I was expecting about 20-30kW extra with Meth, but was very surprised to get a genuine 40kW. And this was repeatable also. 3 back to back runs were within 2kW of this figure, and I just printed the highest which was the last run (so autotune was still running!!). Probably could have broken 280 with more runs, but did not want beat on a customers car.

The dynos are super smooth, and super repeatable. Contact me for more info on the Procede and/or meth. I can also supply the DCI and should have decat pipes in the not too distant future.

Cheers,

Adrian

Looks great Adrian! Those newer maps appear to hold boost taper a lot better to redline.

Why didn't you push the boost up higher on meth? A larger FMIC and more boost would tip it over 300kw/400hp

[adrian@vishnu]

This was a customers car, and I did not want to push it. This is just simple Autotune. It optimised the tune to a nice safe level. I am sure we could have pushed another 5-10kW as is, and with a FMIC I am sure we could do over 300 which would be a phenomemal result.

Any idea what the higher reading N54 dynos are in Australia? Our dyno read lower than US. Also most interested in roller dyno... hub is not really comparable.

Cheers,

Adrian

reviving a very cool and informative thread.

couple of questions:

I don't know a great deal about Procede...

1. does autotune automatically pick which map you go on, or do you pick a map and it 'autotunes' you car for that map?

2. were all those three runs done in map 1? and would map 2 have produced better results?

Without meth, you set the baseline and the vishnu will autotune to optimal settings.

With meth, you set your baseline for non meth and meth (2 different maps) and when accelerating on boost (on meth) the vishnu will transition to the meth map and will autotune

[adrian@vishnu]

Autotune tunes the map that is currently set... it never changes maps. The progressive meth feature will progressively change from map 1 to map 2 based on meth flow. When running this feature, the Autotune only operates when on map 2 (meaning that it only operates when you have full meth flow).

Cheers,

Adrian
