Can i ask if this was a 'live' map on rollers/open road-with-a-laptop-plugged-in? I presume it was?

Any idea on the power increase with just the exhaust and map? I'm thinking of going down this route (I said I never would lol!)

I don't want a massive increase, i was thinking 0.9bar or thereabouts after getting a better exhaust fitted. I'm after a little less lag and a quicker response to throttle pedal use really (mine is a Tip car)


Cheers

Yes, it was done on a 4 wheel RR with a laptop, starting with a tried and tested map and then making minor adjustments to suit. Took about 2 hours.

I have learnt from experience on here (and back in my Subaru days) not to quote what the output was because it will be deemed either impossible, or that the particular dyno over-reads, etc etc. But I can tell you it makes a significant difference the the strength of the 'hand of god' which pushes the turbo along. The throttle response was sharper with just the exhaust, which in my case was 100cel.

I've not looked down long enough to tell you what it is boosting to on the in car gauge.

If you want to know more about the power feel free to pm me

great thread, and i may have missed it, but who did the remap.

I am seriously considering changes to my 996t of 7 years... just popped on some BBS LM's...now for coilovers. Exhaust and remap....and..

I'm sure most of this will be outside of my available budget Sad

DMS carried out my remap (other maps are available, some cost more, some cost less)

@mistercorn - any thought on those intercoolers?

AMD at Thurrock re-mapped my turbo (tiptronic), when they fitted my Milltek exhaust, and told me they couldn't RR test it. Can't remember if it was because it was 4WD or tip!

Even if you disconnect the front drive shafts, the tiptronic box does not like being on a RR - any decent place worth their salt will tell you that - have seen two boxes that developed issues subsequently in a short space of time afterwards.

Most dyno places will refuse to put them on as they don't want the risk of a large bill coming their way.

Two boxes which developed problems out of the hundreds which get dynod isnt that many is it?

And how can you confirm that the dyno was the only cause?

Question

How do you know hundreds get dyno? Call Charlie at http://www.surreyrollingroad.co.uk/ - he has state of art 4WD but will not dyno them - not a new dyno place etc, but someone who actually knows about these cars and has been in the Porsche world for many years.

One of those two boxes happened with 100 miles, the other within 900 miles. Both felt different after being dyno'd.

‘Felt’ meaning? Question

Were these then verified as faults? And if so what were the faults sourced to and how were they resolved? And how was that attributable to the rolling road?

Appreciate that sounds pedantic but I think they’re actually fair questions to ask for what is a pretty big claim in a largely viewed forum thumbsup

How do you know hundreds don't?

As N997B says, i'm not sure 'felt' is evidence of anything?

As a tip owner myself I would like to know what the issue is as I will undoubtedly be going for further tuning in the future. Thumb

You don’t have to take my advice and I am not the only one who will say the same in the porsche industry. But I think I have more than enough experience of Turbo tiptronic boxes since we were the first to push the boundaries and do upgrades on them in the UK. If you disconnect the front driveshafts then you can mitigate the risk to an extent.

In both cases the cars had no issues beforehand and both required new clutch packs afterwards. They felt different to the owners because they both started to have problems with shifting afterwards within a few hundred miles.

Why tune on a dyno when you can tune better in real world conditions on the road ( at Brunters for example ) where you have no cooling or air flow issues together with different gradients that you cannot simulate on a dyno. Dynos are good for a baseline but that is where it ends.
