No - Would seem it that it is a pre requisite for the mag clutch to be engaged for the flap to close. So when it is disabled, no clutch and therefore no flap action.Quote:

Also records the torque commands from the gearbox as it often intervenes. Unfortunately the sample rate is ~ 1/sec. A trade off between sample rate and logged blocks.

Thanks for the spreadsheet. Interesting data and I like the comment notes it helps explain a lot more. I hope the Ross Tech staff reward your effort and IP.
I had really bad experiences with VW as well. My 2006 beetle had this annoying groan between gear changes and when I went accelerate. At first they treated me as though I was imagining it, until the noise progressively got louder and they couldn't ignore it. Went back to the dealer around 12 - 14 times within 6 months, came back 'fixed' about 4. Noise reoccured again. I wrote to VW demanding a new car too. No joy. I was angry, frustrated and bitterly disappointed that my beautiful new car could give me so much grief. Ended up the noise was a solenoid valve (or actually - something attached to it) 10 months down the track, finally fixed.Quote:

Did another run this morning. 32 minutes drive around suburban Melbourne. Supercharger ran for total of 109 seconds or 6% of the time. From a cursory look the average engage time was still just on 2 seconds with the max period of around 3 seconds. XLS is ~ 8,000 lines and 0.5mb. If someone is good with Excel & feels so inclined....it would be good to to work out what the actual min, max and average clutch engaged periods were. along with the number of cycles.

This one shows the Current regulation to the supercharger mag clutch at 0.1 sec intervals. Interesting how if can spike the Amps to 1.5 on engagement and then back off a fraction of a second later. Perhaps this is the PWM doing its thing to minimise engament jolt. Also it appears to regulate the Amps within a run cycle too. Significant point is that there is more to it that just ON or OFF.

Pivot tables are your friend. They will take MBs of data in clean tables and show you calculated values within seconds. They can be graphed with 1 click.Quote:

Yeah me too... Hasn't happend for a while, all though now I notice sometimes when I put smash the pedal down (not when the engine's cold!) I get a total loss of power for a second. Extremely annoying!!!!:mad:Quote:

Yep DSG, but take off from first, shouldn't do that....Quote:
