APR ECU Upgrade MK6 Golf - Customer perspective

[Johnbu]

Hi Guy,

I do understand tyre pressure makes a large difference to handling. I prefer mine at ~32.

Racelogic Performance Databox is accurate and the correct way to test it.

To answer your question, no I haven't tested my car stock or mod, the only way to test it correctly is with a PROPER GPS measuring device like the Racelogic Performance Databox (IMO the G-Tech Pro doesn't fall into this category, but nonetheless useful to determine the difference a mod/change in setting/launch technique makes) Or running it down the 1/4 mile.

I'm not terribly interested in the exact time my car can make, whether it's 0-100km in 6.97sec or or 6.02sec, it's all academic to me, how it feels on the road, power delivery and fun factor is me. I'm happy with the way my mod has improved my car. I'll take it to a drag strip one night when I can be bothered.

Anyway back to the question, yes for a track day I would change tyre pressure, but I will also take out the spare wheel.

But to compare a stock car vs a chipped car 0-100km test, I would prefer to keep the tyres of both cars at the recommended settings by the manufacturers- 30-38psi, so you can compare apples with apples.

Anyway, this isn't a dig or complaint about APR or any other brand.

I'm impressed by APR cars at the grag strip. I respect your products.

But really, is there a point on showing a youtube clip seeing recorded by some guy accelarating his car on a mobile phone and claiming 0-60 flat 5. We all know the speedo on the GTI is optimistic at best.

Show it done measured with Racelogic Performance Databox and I'd have some interest.

But if you're going to claim it can do 0-100 in 5 flat by showing a youtube clip, you can't then turn around and pass the onus to the youtube poster to prove it's validity.

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.)

Adam, please note that the MPS is throttle/torque limited in first and second gear.
this is done to limit torque steer.
that is why the 3MPS doesn't feel very quick off the mark.
But on the highway a 80-120kmh time of 3.5sec is not too shabby.
this is where the car shines, it really is an Autobahn stormer. (for a rice burner)
rolling accelaration on the highway a stock WRX STI can't keep up.
But dragging off the lights, it's a bit average, untill you hit 3rd gear and 3,500rpm and then your getting all the 380nm.

I think you would find a good difference with wheel spin even with an 8psi pressure variation. Obviously road surface & temperature also plays big factors in traction / grip.

I suppose this is why when you see 0-100 times recorded by magazines, the times will often vary 1.5 seconds (above or below) what the manufacturer claims.

I certainly know with the Golf R, you are trying to get wheels spin to stop bogging down, on the GTI, its more the opposite. Like the WRC cars are quicker 0-100 on the dirt than they are on the bitumen when using the same tyres.

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....

+1 makes the car a lot more fun and what it should be from the factory. Would be the single best upgrade IMO.

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

Damn, I'm in awe.

I'd love to see results from a MkVI GTI (EA88 DSG customer running stage 1 and timing with a GPS accelerometer. But if low-mid 5s are possible with a good launch (damn, if anything sub 6 is realistically achievable) - which presumably means you'd be getting into the 13s - then how could you not seriously consider the upgrade!?

Ah yes, I've just noticed this on the APR website:



Good time to call your APR dealer then!

Hmmm, I've only had my Mk5 Golf GTI for 2 days now.
I guess now is as good a time as any to go to APR Stage 1. Merry Xmas to me!
