S50B32 Vanos vs non Vanos result.

[PSI-Motor]

We just started to tune this evening. Nevermind the Hp and Torg figures they are not correct. Final result and correct numbers will come in short

Look att the torq and hp between non vanos and vanos and we just got started!!. This car has an EMU ecu of course and running in swedish Timeattack series The curves are not linear and a bit jumpy due to a vibration problem that effects the reading.

Of corse when you have 60deg of travel on intake cam and 40deg on exhaust
Also it`s important at what timing you`ve parked non vanos setup.
In my opinion it`s not so relevant at high-rpm time attack application, where good trade-off for top end with fixed timing can be found.
But in general vanos is great technology and it`s really good we can manage it with EMU.

This is done only by vanos non of the other maps were toucht
Calibrated the knocksensors, time to adjust the timing

The area under the power curve will be always greater for VANOS than for blocked VANOS, so the track performance will be better.
Personaly I love any VVTi systems and I can't understand why people do not use it.

Please post your dyno graph after final tune..

I love them too
Demanded camangle and real camangle is extremely accurate
Will do Jadzwin.

Ppl don`t use it because it`s not an easy task to get vanos work with EMS. I remember when i`ve done it 1st time with other ecu it took about 3 weeks to get figured out triggering & setup. And 1 season later after customer locked cams we lost on dyno everywhere.
