I think it depends how you drive as to which version of the software you would like the best. Close on 150 Polo's with V 1.0 & no complaints about the code.

If everyone likes the V 2.0 it would be easier to remove the V 1.0 to save confusion

lol well an aftermarket ecu and dyno time would cost way more than a flash so no other option than go a flash lmao

I'd pay to have it on switchable with V1 (and stock). I haven't even driven it yet lol

Guy, is the APR tune able to be tweaked for better performance depending on mods to car (eg just reflash for standard car but retunable if exhaust changed etc) or is it just a generic reflash?

Well remembering that its an ME7 ECU, the adaptation is huge - a 4" intake & 4" exhaust wont require a retune.

A bigger turbo (which in turn requires more fuelling) will.

So in depends on your definition of "other mods".

As you can see, the cars that have added intercooler, exhaust, intake have no retune & the sum of the parts equal up to ~ 15wkw.

It may be possible, but without a larger turbo, how much labor would you pay to gain an extra KW or two (because I'm positive you wont see 5kw!) ?

Thanks for replying so promptly.

I was just wondering because I know there can be quite a large difference between a reflash and a retune once you start doing a decent number of mods. On one of my previous cars I gained 20kW atw with a retune just to maximise the potential of the mods I had.

As my experience in street cars is limited to Japanese and Aussie I was wondering if I could expect similar sorts of figures once I'd finished the Polo (I suppose I've got to start it first ).

[Guy_H]

From my experience with a Japanese or AUS ecu in a car, you are probably correct.

A Jap car (I'm talking Evo 8 / 9) - its sample rates & control mechanisms are so archaic compared even to a Polo (which is now sort of two generations old).

Bit like Polo = Pentium 2, Jap = 386.

Imagine playing "need for speed" on either of those.....

What are the chances of getting it switchable with V1?

IMO, there would be little point switching. Either stick with V1 or make the move to V2 if that file suits you better.

Depends where you're driving.

V2 might be better in traffic and V1 better on the track.

Can't hurt if it's possible. Better than having a 104 tune considering that's like $8 a litre.

Been readin through your post guys and a dont wanna sound a Newb but is this Stage 2 you are talking about?? Over here its £150 to move onto stage two from stage one, so am not sure if you are talking about a patch on Stage one?

Yeah, it is 'Stage 2'. We've (Guy has) renamed it version 2 because it's not really much different and doesn't seem to require other mods for its benefits.

Unfortunately the way the switching works & the tables that get transposed, its not practical or economical to try to get V 1.0 & V 2.0 on the same ECU.
