118TSI - General Discussion

[verbalhologram]

Make sure you explain them exactly what's happening. Initially I had a few knock-backs, like "we haven't found anything wrong" only for the problem to continue. Now I always ask for a mechanic to go for a drive with me so I can demonstrate the fault. I usually 'practice' before, so I know when exactly it would occur, so I can demonstrate it easily.

Thanks for that mate, will be sure to try and be clear and ask that I can take one of the mechanics for a drive to demonstrate the problem.

Found a suitable flat road for testing the acceleration of my APR Stage 1 118TSI DSG (few a few of the heavier options ticked). I knew it was around 6.8 seconds to 100kph but wanted to do a better test using the Torque Pro app for Android, connected to the car's OBD port via bluetooth.



Using Sport mode with TCS on. Just get too much wheelspin with it off. Needless to say I'm pretty impressed. The 1.4L twincharged slightly beats the GTI and matches a stock Mk5 R32.

Actually if anyone has a GTI with Android phone I'd be interested to see their result. Torque Pro costs $4 and the bluetooth adapter is about $15 from eBay.

^ excellent result Ryan

Does the app rely on the accuracy of the test cars' speedo? If so, Golf speedo's are generally optimistic.

The OBD speedo is more accurate than the MFD one. @100kph the MFD is out by 8kph on my car, OBD is out by 3kph (assuming GPS and advisory speed traps are accurate). The car has to know the real speed otherwise your odometer would be out. You can test by setting cruise control to 100kph (MFD), then holding OK to clear your stored values, then watch the Average Speed show you something like 94kph.

That's awsome. I just ordered one of the bluetooth jobbies for ****s and giggles and was wondering about how they go.

Just for reference, I had no trouble getting 9 secs in a standard 118tsi manual with the stopwatch in my hand and the 100km/hr being 107km/hr on the speedo. There's a good lag in hitting the start button and then fumbling to stop it.
I was pleasantly supprised, as the manufacturers specs say 8 secs.

I'm still waiting for mine to blow up under warranty but it seems to be going fine.

Well my warranty runs out this week so maybe I'll have to start slowing down a bit more

My bold. Therefore your true time would be nearer 6.7sec (6.5 x 1.03), because your car is only doing ~97 when OBD thinks it hits 100 & 100 when OBD thinks is its 103. Either way good. I think I was doing 6.9s when I played around with mine 3 years ago. The canbus speed (ABS wheel speed sensors) or what you are calling OBD is spot on in my car. Zero error at 100kph when measured with VCDS.

[Ryan_R]

Not too fussed, haha. How many cars do you come across on any given day that are quicker by a few tenths.. or quicker at all for that matter? Maybe once a month for me. Did you make any changes to get your ABS sensor speed accurate?

Ryan R, can I ask which OBD BT device you purchased via ebay for the Torque Pro app? Keen to give this a go asap. BTW, there is a new update file for APR stage 1.
FYI, this my 2nd update since original install 3/12. Have you had a run at a drag strip re 0-400m time?
