APR ECU Version 2.0 loaded...!

[MACCAA]

Don't think you have to worry about increased fuel consumption with V2.
My Oettinger version was showing 5.9l/100 on the run back from Oran Park to home......[31k mainly freeway/backroads @80-100kph,6k normal suburban]
Normal suburban running appears unchanged.It's all in how you use your right foot...

EDIT: how is Timbo's max torque 598.5Nm?..... thats nuts

Fair call - bit hard to compete with 600nm. ..and Sam, my V1 run hit 320nm, my V2 run hit 362nm = 42nm

The central function of a gearbox is to multiply torque so -- as the run was in 3rd gear -- you have to calculate back to a direct figure...which I think was about 320Nm on that run

oh....so 32Nm behind APR V2. well that's a shame, a bit of catching up to do there... *stir stir stir*

i think we really do need to see the programs run on at least the same brand of dyno, and in the same gear. fairly inconclusive comparison otherwise.

I agree, but actually the chances of getting the cars in the same place at the same time is always going to be remote. However, I would point out that the curves are now quite similar.

Quite apart from that, I think it's great we have so much choice in terms of 'off-the-shelf' tunes for the Polo: it doesn't always happen with other marques. And while we might (seriously or in jest) defend the choice we've made, the reality is that this competition benefits us all.

Actually, my V1 run did hit 340Nm, but only for a moment.

Actually only Eddy's car run on same dyno / same day / same car / shows the difference between the curves.

When we are doing all our power runs now, if the base line dyno is more than a week or two old, we can not use it - we have to redo a baseline & then the mod dyno straight after it again (costs us more, but we get consistent figures).

Therefore if your base dyno to mod one is any time apart, it could be out 15% or more (as we have proven) - its a pain in the bum, but the only way.

Fair enough. I have controlled all variables, with the exception of 'same day'. Another difference between my run and Eddy's is that V2 had one week to adjust and bed in my case. Is there any disadvantage or possible inaccuracies in loading a tune and then immediately running a dyno if it hasn't had time to adjust?

[Guy_H]

We did a fair bit of testing to try to get a handle on "adaption time" and its tricky, but we could see from Eddy's boost & timing logs that it adapted straight away (he had good fuel) - we let it idle for 15 minutes so I would say it was 100% OK.

Its more the dyno correction factor I would worry about.

Same you couldn't get up to the Brissy Polo Dyno day, we had the operator run through how all those variables & how they work, and how even a week apart, they can be 5 - 10 - 15 - 20% out!

Adaption after a week (adaptaption is constantly happening) would more account for fuel / temperature / altitude (air density) etc... But your dyno results are some of the best controlled ones out there

I reckon my results are fairly modest ..123kw aint earth shattering.

I reckon my results are fairly modest ..123kw aint earth shattering. But the shot-gun blast torque (and plenty of it) definately means one thing, ...the dude who wrote the V2 file qualifies for a bonus ..or at the very least a few cases of Coopers

I just spoke to him, he said to give the coopers to me for safe keeping

[Chipped]

Any version2 drivers out there considering goin back to Ver1??? he,he,he

Had the V2 flashed last week and highly doubt that I will go back to V1. Just love the extra low-mid range power/torque and I dont notice the power dropping off too much above 5000rpm....might have to with the mods that I have though.

Wow, he made great software and let you have the beer. He must be a really top bloke

[Kai]

In all seriousness.

If you want to go faster in a straight line and not in a mountain. Is V1 the go?

Obviously for mountains V2 would be better.
