APR ECU Upgrade MK6 Golf - Customer perspective

[MurphyTheElf]

Guys, what are the typical 0-100 km/h times that people are seeing on mk6 GTi with APR Stage 1 ?

DSG ~ 5-00 seconds flat. about 5.5 for the manual. Hooking them up is the trick.

5 seconds flat for a stock DSG GTI with only an APR stage 1 tune? So it improves the stated stock launch by almost 2 seconds??

yep, but as above, negating the wheelspin is the trick. Running about 18psi in the tyres helps.

Guy, is that a typo? 18psi in the tyres? I would have thought 38psi...

Less wheel spin, not more

Whoa.

The figures I've heard bandied about are that a stock DSG will do somewhere between 6.5 and 6.9 (I've not seen any magazine test faster than 6.5), and the stage 1 improves on this by approximately half a second. I'd be hugely impressed if a stage 1 could manage a sub-6, let alone a low 5.

Guy - how much of this, in your opinion, is down to super-low tyre pressures? What's a realistic time in your experience for a DSG car running standard pressure (38psi) 18s?

(Just a point of comparison - a Mazda3 MPS manual tends only to manage a low-mid 6 time with very similar power, torque and power/weight figures to a stage 1 GTI.)

Hey Adam,

I don't have a DSG, but you can see that video above, that's 5.5 seconds with wheelspin, Stage 1 only.

On my MKV with a manual transmission, to achieve a 12 second 1/4 mile on street tyres, we ended up with 18psi in them - our MPH was still exactly the same, but our 60 foot time came down by a second.

As I mentioned - negate the wheelspin & you can get great times, one way to do this is to lower the pressures. Maybe some other DSG owners can chime in?

Anyone who thinks that the APR Stage 1 ECU only reduces the acceleration by about half a second seriously needs to go to their local APR dealership and get the TRIAL ECU installed NOW NOW NOW!!!. Lol, half a second....

Sub six second times are so simple my post-retirement age mother could do that. The video that was posted on the previous page just shows how easy it is.

5 seconds flat would be hard. But as Guy_H said, you can always drop your tyre pressures to low levels if 0 to 100 is what you're aiming for. There is always going to be a compromise between corning performance and straight line performance when you're aiming for the ultimate in one disipline though.

Not to troll, but how was that claimed 5.51sec 0-100kph run measured?

By looking when the (optomistic) speedo reaches 100kph?

I'm just curious.

But really, what is the point of dropping your tyre pressure down to 18psi?

The performance of a car should be measured on the basis of how your car/tyres is setup on a daily basis. Unless you like to destroy your handling and tyres by driving on 18psi pernamently.....

John,

I'm not sure how experienced you are in car ownership, but tyre -pressures have a LOT to do with traction & handling of a vehicle. On the Michelins I have here, minimum pressure is 20psi, max is 50psi, so a 30PSI "working range". If you ever go to a track, would you change your tyre pressures up or down to suit grip & wear?

32 PSI is great for street grip on your average good road tyre, 42 PSI is great for wear - so 36 - 38 PSI is a good "compromise" between grip & wear. For maximum grip, lower pressures, Maximum wear (and better fuel economy) higher pressures.

We measure all our acceleration data with a Racelogic Performance Databox, same as the magazines use (as they end up testing most of our cars). I don't know what the Video Poster used (maybe you should ask him), I know Fab uses the G-Tech Pro for his.

Have you run your own 0-100 times in your car stock vs modified? or are you guessing you have an improvement because it feels different? (Serious Question). I would love to see your testing results.

Actually this topic needs it's own thread - especially since its GTI related not Golf R.

A quick You Tube search revealed plenty of video's of 0-100 - maybe we can split this thread?
