APR ECU Upgrade MK6 Golf - Customer perspective

[Finance_Analyst]

so i notice now with the tune that the 2nd to 3rd gear change has a much louder blip.

also, even taking off in 1st gear it just wants to go - have to feather the throttle to avoid wheel spin!

I have the full stage 2 APR upgrade ...everything you can think of I have had put on my rocket ..and I freaking love it!!!!!

FMIC installed too?

[Sebast]

that was the very first thing I had upgraded ...

[Brendan_A]

Nice! Did it make a big difference?

[Sebast]

oh yeah ...especially in summer!!!!

after 1 week of some hard driving and normal, I have noted that my fuel consumption is hovering in the early to mid 9s.

Given that VW quote early 10s, this is defintely an improvement. How did APR manage to simultaneously up the boost (circa 16 psi) but also improve fuel economy? I have read that APR claim this should be the case in any event, but still pretty amazing that you get the best of both worlds. What else does the stage 1 engine remap change (other than boost and fuel pressure from what I was told)

I thought VW quote better than low 10's... but anyway the crucial change that tuners make is the ignition timing.

Also, allowing more boost down low can improve efficiency by reducing frictional losses in the engine; ie. using a lower rpm with more boost to generate the same power as higher rpm at lower boost.

You have to also realize that having more boost available doesn't mean you are always using boost; if you drove the car hard all day every day, every aftermarket tune will result in worse fuel economy as more boost = more air = more fuel. But during standard day to day driving, the aforementioned changes improve fuel efficiency.

MkVI GTi DSG - Urban: 10.2, Extra Urban: 6.1, Combined: 7.6 (see the current Golf brochure)

I guess Finance_Analyst is hooning about Toowong. But a better comparison would be vs previous mileage rather than VW's brochure.

City driving figures are always the hardest to quantify, but we would normally expect to see a gain as you have.

Honestly, there are hundreds of interlocked tables that are modified - that's one advantage of using a tuner that can write / rewrite the entire ECU - where the others that can not access the full ECU get mixed results.

Glad it going well!
