R36 standard (factory) ECU tune, where to obtain?

[guest12345]

I don't think it works that way. The tune should be working as soon as the car gets onto the road. It's not about wearing in or something in this case.

just replying what i was told, the guy said that ecu uses some sort of memory system.

Nope, it has been about 4 weeks now and the fuel consumption is actually getting worse!
I am very hesitant to do anything at this stage until I have a clear understanding what the problem is as I don't want to make it worse than it already is....

oh, i didn't know that, probably should check it out, maybe go back whereever you got it tuned and ask them, afterall there is a warranty of some sort.

BTW which tune was it?

I can usually get the stock files for most ECU's if you get really stuck. If they are Australian specific its sometimes a bit more difficult. For most models there is more than one ECU hardware and software combo available eg MkV GTI ecu variants are over 40 FFS . As another example I suspect the Mk4 R32s here though may be only 1 or 2. Surely the tuner would have you cars original rom stored somewhere ?

I think we are doing an R36 soon but I've explained to the owner not to expect much. Many NA cars run maps that are very close to the limit with lots of knock correction capability allowing you to push the limit. You might get a couple of degrees of advance if the car was specced for 95 RON though. The other big gain is where they torque limit things to broaden the gap between models and I'm told(hope) this might be the case here. If we don't get something decent we won't charge much at all probably only dyno runs.

When the car is flashed it has stock values, over time the car learns and adjusts. This is why you see people all the time carrying out on about how great their car felt after service and the dealer must have performed an update when all that occurred was the battery was disconnected.

Huh? So if you get a big gain you charge people more?

Wow! yeah that does sound dodgy!!!

Yeah heaps dodgy...Maybe I should have phrased that differently but think about it If I waste a whole day on the dyno after someone requests that we try to get some more power out of their car and lets say it doesn't produce anything worthwhile. Then what, I just say sorry mate my loss good bye. I wouldn't touch the car if that were the case

My costs are:
my time
dyno use=$ + facility$
ECU defintiion from SW provider
(HW&SW)/car

Or do you mean I charge $1000 regardless maybe throw in some excel generated dyno plots LOL

I mean that I would probably charge between $100 and $200 dollars

This might just be me, but I would think that any decent tuner (and I'm not saying you're not decent) would KNOW what sort of increases can be expected and advise customer of a range they can expect (estimating slightly low) and then say "it'll cost this much" and then charge them that.

Rather than waste a day, get nothing and charge nothing. Then have someone who has the same amount of time spent spend $1000. That sort of business model seems flawed.

And I've had three different cars tuned by two different tuners, so it's not like I'm talking out my arse.

Actually I do know what the result is likely to be, I have both power and torque figures BUT I haven't done one here to the point of dynoing things to make sure there is absolutely no doubt that there is something decent. I just like to test every tune myself that's all. There is a lot of BS around when it comes to power and torque gains, lots of pretty graphs and farcical back calculations etc etc, I just don't work like that.
A Turbo car is a different story you know you can always get a decent gains out of things where the hardware permits. If you gained say 30~40kW then you could safely say the tune will produce 30kW. In this case its closer to 10 atw give or take and on 98 RON too. I hope that makes a bit more sense.

Thank you, I will keep in mind.
The Tuner did re-install the original tune, however I suspect that he might have lost it and installed one from another (similar) car/engine, hence the high fuel consumption.
I might discuss my concerns with the tuner, but suspect I already know the answer; Just re-install the ECU tune..... That might indeed fix my fuel consumption, but still does not explain why the car is using so much fuel on std ECU compared to pre-tune. I like to understand things before making a decision as I don't want to dig an even deeper hole......
Yes, plenty to consider, that's why I thought I start this thread, to see other's opinions before I make up my mind.
It also provides others with a bit of insight and that ECU upgrades for the R36 are not always that straight forward/effective as sometimes promised. I was promised substantial gains by a person that is rightly not connected to this Tuner anymore.

Thanx.

Some funny comments in here...

Firstly, have you scanned the car with Vag-com? this should show you if there is a fault with the car...

When you are talking about aftermarket tunes, there are 2 varieties, off the shelf and custom.

With off the shelf, you know what to expect because its all been developed and installed in a few other identical vehicles previously.
With custom maps, the tuner may have an idea, but as its actually tuned to your vehicle, it may be better or worse than expected. If the car has done high kms and been babied, I would not expect to get the same results as a new vehicle with some light mods.

As for your OP, I'd take it back to your dealer and say it has recently started chewing petrol. If you had a tune that is 'invisible' as APR claim, then you'd expect the dealer to reflash it to see if that fixes the issue... Although this could just create more problems, all depends how well you play dumb and how quickly they want your problem fixed without investigating.
