Retune - the last mod?

[Guy_H]

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'.

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!

Sounds good thanks Guy! Might start a list for those interested in a new thread so not to clutter up Ben's thread anymore.

Happy to see busy threads in this section

Since you aren't looking to make any major hardware changes I think you should finalise any minor mods before getting the new tune (unless Gavin is willing to give you a free revision down the track). Then you can be pretty certain the tune will be optimised for your setup.

I couldnt agree with this more.

I cant beleive this is still going , and its over a couple of KW's !
Whats the most you'll gain from one tune to another . 5 maybe 6 kws ?
Spend the money on hardware . Spend a little more and get a KO4 and a mbc . You'll get 10-15kw more and a bucketload more torque , all while making the same boost as a ko3s !

Hey Guys

Great thread im really enjoying reading it all. Giving me a lot to think about. So many knowledgable people around. Really look forward to seeing the results of the dyno run. If only i wasnt in WA.

Agree completely, I also dont believe there is more than a few kw in a different tune .... spend on hardware, thats where the major gains come from.

Sharkie my problem with that is some tunes don't neccesarilly get as much out of the same hardware as others, so why would I buy a part for example an exhaust when I dont think one tune could get as much power out of the same mod as another.

Because the differences arent that great ! Looking at all the figures the turbo is really the one thats limiting any real power gains , until thats changed your looking at only a few kws difference between the tunes

[jasn78]

Seb, I get that but what I am trying to say is that if im say 6kw difference with the same mods and different tunes now I would think that going a larger turbo with the wrong tune would only further exhasperate the difference in kw made
