Retune - the last mod?

[Sharkie]

That was the same day, same dyno, same operator and temps mate back to back. I just went back to the same place after to see what I gained with the correct rated spring and so did the other APR with K04 when he changed his FMIC.
!

Not disputing your power Ant, it's more about what you have spent to date to make similar power to the K04 .... Point is if you did all that work and had a K04 where would you be? Close to 160wkw, I'd bet ......

[VWindahouse]

Yeah sorry you're right mate! I have spent a bit for sure, so it would be close in the end. 160 would be very nice if only that damn ebay hybrid friggin fit

[leitch]

Sweet, what's the Jmac fitting for you

FMIC and piping is the only one that will really make a difference on the dyno, but also S3 brakes and some other little handling bits. Really looking forward to it. Will follow it up with some exhaust work (DP mainly) and some lighter wheels hopefully.

Love that there are so many Brisbane Polos keen to get together for something like this.

We can do it on a Saturday, but will have to be after July 1st - we have not moved into the new building yet so give us a few weeks!

I think I pulled a 138 on my last run ages ago, but the torque came in late.

The most expensive thing on my Polo was the APR tune, if I want more boost I feel moving away from APR will be the outcome, any which way.

To be clear, my car is strong. There is nothing strictly wrong with it, but I'm going along with the feeling that I want my Polo to always feel like it does on the good days. Sometimes it seems lacking, logging it revealed nothing wrong, I put it down to the adaptive tuning which needs to be worked against.

Unsure if this is a bad expectation...
Happy to loan my car to the right tuner to confirm / disprove whatever they like, as long as the Polo comes out better from it.

There is no "adaptive tuning" as such - you have set timing & set boost tables, the car can't change. What does change are environmental conditions - heat, humidity, altitude.

More boost is definitely not the answer on a K03 - if you understand what happens when turn the boost up - you lose power & generate heat (shortening component life) - if you want more boost, select a turbocharger firstly that will make it (but that's working backwards - we look for what power you want, then select the turbocharger).

I say more boost FTW, go hard or go home.
Maybe if it was a newer car i would be more cautious, but you can pick up a engine these days for under $1000
Plan on doing pistons etc oneday

No adaptive tuning? Now this is interesting...

So after a tune is installed for the first time, it's been said numerous times it takes a while to bed in or adapt.
I know of Atleast 1 person who reset their APR tune before a dyno's run as they felt this would give them the best results
I've also read numerous times that a tune can feel lazy and can be better after a hard run.

So this is all wrong? I agree about environmental changes, especially heat and humidity, but I was definitely under the impression there were coding elements that tuners did not touch and are dynamic.

I agree about more boost not being the answer, more boost in combination with more timing without upsetting the knock sensors is the right direction IMO.

From what I understand, most ecu's have a 'base' map with initial settings. It then has a certain range that it can tweak fueling, timing, etc more or less depending on conditions. I think what Guy means is that you couldn't just chuck on a K04 and expect it to learn that it needs a s%$tload more fuel. It has limitations on it's 'adaptability'.
