APR tune price hike

[VW Convert]

I noticed yesterday with the 36 degree weather in Sydney that the car was -significantly- down on power due to heat soak etc - obviously it's the stock ECU limitations kicking in and pulling timing to compensate. Do flash tunes compensate like the OEM programming does, or will you get lean scenario?

Always thought this was the laws of physics kicking in, higher temperature = lower air density, lower air density = less oxygen, less oxygen = less fuel can be burned, less fuel can be burned = less fuel is injected, therefore = less power.

I may be wrong though.

It's (arguably) safer than flash tuning. A tuning box keeps within the safety parameters (fuelling, trim, timing) of the OEM programming. That extra 1/8th you're getting with a flash tune is due to being able to exceed the OEM limitations.

Anyway, to each their own! I've had Revo flash (in the MK6), and a JB1 box (in the MK7) - I'd go for the JB1 again in a heartbeat!

That is because the tuning box can not compensate for the inputs (Including intake temperature), it can not control timing & can not control fuel. It's basically keeping the wastegate closed more & hoping (Fingers crossed) that the ecu can keep the temperature & mixture under control. All its going to do is pull all the timing (near limp) as it can't pull the boost back to where the ECU wants it safe.

And also other things like R&D for the local market and environmental conditions, proper safe and tested integration, and local support.

Each to their own of course, but I'd lock myself in a padded cell before I'd fit a tuning box to my car. Having an engineering background and a reasonable understanding of how these things achieve the power they do, I'd much rather keep my car stock!

Spot on Adam. We have removed several JB1 boxes from N54 & N55 BMW's (as well as the F20's) - difference is like night & day with a proper flash tune.

i dont know if you guys with tuning boxes and stuffs do use your cars on race tracks... but one thing i know, 2 of my friends are on APR tune and they have been pushing their cars harder than anyone with common sense would do on public roads unless you hate having driving licences and your cars (hoon law).

and they have not had any single issue with the APR tune. 👍

Yes I fully intend to swap over to APR or similar tune once the warranty period is over. Listening to the concerns over tuning boxes, I feel I may get away with it being from a milder climate down here in melbourne. I probably would plug it out on a extremely hot spell.

Comes down to personal circumstances, I want the warranty with no TD1 tags from the dealer as I want to service it there too (due to a good deal I got), I don't the best power increase as I'm happy with a moderate increase and then of course there is the price. By time i get around to remapping I expect the USD and AUD to have resolved their differences

You must be joking. The Reserve bank's policy is to attempt to get the AUD even lower. AUD1=USD1 was an anomaly and I really doubt you'll see it again in the next 20 years. It was only 10 years back that I was buying machinery at AUD2=USD1

Plenty of economists saying the Aussie dollar hasn't bottomed out yet too. Some economists predict it will drop to low sixties during 2016 and stay that low throughout 2017 but even the most optimistic are saying high sixties by early 2016. Doesn't appear likely it will be bouncing back any time soon.

I hear you Guy I work in the truck parts business mainly sourcing from USA, the cost increases are destroying our bottom line!

you need to work out what you can produce locally & export rather than import. It makes it hard to run a business based on imported product, especially if you aren't big enough to hedge the forex.
