APR ECU Version 2.0 loaded...!

[jasn78]

And guy dont worry i know how important that last 001rpm is lol

[Timbo]

Look in the dyno day thread.

Thanks ...I meant just V2 on an otherwise stock Polo

Oh... I don't think there are any. UK Polo's might have this done but AFAIK noone here has.

small update: i had a bit of a drive last night and was in the merging lane at the lights. i gave it a good punch (don't worry - 80km/h zone) and was very impressed with how it got the power down, it definitely felt quicker - not much but enough to notice.

to compare it to how it was before, i had a passenger in the car with me last night (which i'm sure you'll all agree has a significant affect on accellaration - especialy from standstill) and it performed as if there was no one else in the car and i had lost 20kgs (i wish ). i now wish i was by myself and results would have been even better .

as for fuel consumption, it doesn't seem to have noticeably changed just at the moment, but i haven't really driven it enough to know. the big test will be this weekend when i drive a fair bit.

i doubt the new settings are fully settled in yet so at the moment things are looking good.

Cheers,
Rhys

UPDATE: ok, so the weekend has ended and i have given the car a good strap with the V2, and i am confident in saying the new settings are fully worked in now. <---this says it all

My opinions: fuel consumption does not seem to have noticeably changed. i did use more than usual this weekend but i assume that has got to do with the way i was driving the car........sensibly!

performance wise i have the same opinions as before, the torque and smoothness IMO is improved significantly.

my next mod (after i put on my stubby antenna and bonnet pinstripes at lunch time today) is the APR engine mount insert so the ride quality (under power) and power delivery will feel like a dream.

Hmmm ... how much is a slab of Coopers these days?

Rhys, I have V1 and the first thing I noticed with the engine mount was improved low end torqe and a smoother acceleration curve.
will be curious with the V2 and dogmount results.

Just had V2 loaded. Gave it a decent thrash so the settings would adjust quickly

First impressions - it seems smoother down low, particularly in 1st and 2nd gear, that's usually where you weave in and out of conjested traffic, very handy and more drivable in that sense. What's interesting is when you hit the gas between 2000-3500rpm, it kicks a LOT harder than V1, although it seems to require slightly more acceleration to get it going (compared to V1). This might be due to the lack of timing pull that Guy mentioned. The boost gauge seems to tell the story. It can spike as high 22psi before settling to 15-17psi. ..and once you shift to 3rd, it's still running pretty high boost. However, all this comes at a price ..it seems to taper off at 5000rpm, ...with V1 there's lots of power coming through until 6000rpm.

..So is it a better tune? Hard to say. Despite losing some high-end power, increased low-down power has its advantages too. The power band is very responsive between 2500-4000rpm, which is what enables you to accelerate out of corners and build speed quickly. In the real world, how often are you utilising the power band between 5500-6500rpm? ...probably not that often.

Also a good idea to upgrade your DV for V2 because it runs higher boost to sustain increased power across the mid-range.

Drive it for a few more days Neil and then give us some more feedback. I'm keen to hear your thoughts then.

[GT3]

Took it for another blast early this morning (outside temp 3.5 deg).

[RhysQ]

V2 seems faster too, even though it doesn't have more peak power, the improved mid-range power and torque translates into more speed.

good write up there Neil!

in regards to your comment above, i completely agree with you. i definitely think it feels faster. from a launch start the torque comes on hard and fast and stays solid through the range (until 5k when its a good time to change anyway).

good comment about the rolling accellaration with having to use a bit more. i noticed that as well. but in a sense it is more driveable cos with V1 sometimes the boost kicks in when you don't want it to which makes for a jerky ride (especially when you let off the gas and the whole car pulls back suddenly ). haven't really noticed this as much with V2.

[Lams]

Took it for another blast early this morning (outside temp 3.5 deg). It really does go hard with V2, the mid-range reminds me of how my car accelerated when it had 145kw atw. V2 seems faster too, even though it doesn't have more peak power, the improved mid-range power and torque translates into more speed. Thumbs up from me on V2 ...uprated exhaust, FMIC and V2 = awesome performance. On a mission to source a FMIC now

Neil, you're not serious are you?

[VW GTI]

Neil, can you stop editing all your posts after you've typed them

I keep having to go back and read what you've re-wrtitten. Just write what you want the first time

I want to get mine done soon, but need to sort something with my electrics out first.

By the reports (and please don't take this as an attempt -- or an excuse -- to start a chip debate) it sounds like it is fairly similar to the way the REVO Stage 1 delivers power. Hence my interest in seeing a dyno sheet from an otherwise stock car, to show the curve.

Since you've said it I will say it too. Sounds exactly like the GIAC tune.
