What remap would you recommend? Mk5 gti DSG

<< < (9/9)

As for aggressive on a k04 there is only so much you can do as the boost its alway limited at somepoint at every stage. Stage 1 limited by emp and heat
Stage 2 by fuel volume and running into compressor surge
Stage2+ by compressor surge sub 3700rpm
A car will feel epic when mapped into the surge point and will seem faster lower down.  But again the surge is something i aim to reduce and avoid at a compromise to the initial low down aggressive feeling.  But 4000rpm + on stage2+ with the supporting hardwares there is the room for us to tune to 400lbft if the customer wants that kind of raw grunt.
The way forward is an anti surge compressor wheel to remove the surge flaw from the turbo... then its torque from 2900rpm with no flutter.    The biggest worry for customers when they come in is surge they ask if it's possible to fully remove it, 80% of cars coming in are already tuned and the customer knows what they are wanting from their tuning session.   Customers can come back when ever if they are not happy or want something changes to match their needs more.

Map switch is only used on stage 1 and 2 cars where the clutch is a worry to allow customers to remove torque at a later date to stop clutch slip instead of having to come back to be detuned or / pay for a new clutch.

Min requirements for stage2+ is a clutch so we offer a full pid based map only for better refined boost control at the higher faster ramping boost demands.

if a customer is not happy or needs questions answering we offer a life time off ownership free support and help when and where we can.

rtechniki:
The car which went back to Revo, was this the one were you wanted the most power possible from the k04 so you didnt have to fit a tte420 to fill the void after owning a tuned TTRs/rs3?  But during tuning you point out the car is only running a stock clutch for stage2+ and our 2+ tuning says a performance, clutch is needed, so I said I would remove all the torque from the lower throttle demands and "try" to get maxinum power just at WOT to give the clutch a chance of lasting and not slipping from cruise loading up?  And the peak torqued was shifted right up the rpm range past 4k to make the power delivery more progessive and not loading the clutch up at low rpm in higher gears which at the torque level you wanted would have killed the stock clutch in no time?  And on the back to back graphs you could see we reduced the spooling over the revo map to try and balance your requests with the hardware we had to play with.   This maybe the wrong car but its a reflection of what we have to juggle daily here.     If yoy was not happy or wanted more throttle or loading to give the oem DBW effect back all you had to do is phone and ask to have the map adjusted or at the time of test drive.

My 2p (regarding partial throttle). R-Tech maps are the only maps I've had that are completely smooth and predictable going through various throttle/load positions. There's none of that sudden boost out of nowhere situation when you just want to get moving without drama. Other maps always seemed to have a bit of 'indecision' about them. Easily confused.

It's worth noting that the other maps I'm talking about were on different engines. 1.8T, AJM, etc. So my point may well be completely invalid!

It's only k03 Stage 2 so I don't think it's got 1:1 throttle mapping, but for what it is, it's very good. I can't pick any faults in it.

If and when I go k04 I have the option of having the mapping done along with the hardware, at Statller. I assume it'd be Revo. To be honest I'm 50/50. Would I gain that much by staying with R-Tech? Possibly. Would there be an advantage to using the same guy for hardware and software? Probably. If any issues arose after the conversion I'd imagine it'd be easier to diagnose and sort by effectively trusting Steve with the whole responsibility from the start. Best way I could word it but you get my point.

When I had misfire issues on the current map I got the impression there was only so much Steve felt he could investigate as it wasn't 'his' map. He did infer that the R-Tech map was running a lot of timing and could have been causing an issue. Which kind of put me at odds between Statller and R-Tech. Ultimately it got sorted with refurbed injectors but keeping it all in-house probably has its merits in some cases.

Anyway, my point is that it's not always as black and white as saying tuner A is 'better' than tuner B.

Bit of a ramble that

Nah it's all good.  A bit of healthy debate doesn't hurt  :smiley:  There's a difference between arguing for the sake of arguing (or trolling as yoofs of today like to call it), and trying to gain a better understanding with the hows, the whys and the science behind it.  I for one don't take anything on face value and like to dig deeper.

I will say that Niki is one of the most community spirited tuners I've seen.  Always happy to share info and doesn't take questions or criticisms personally.  I only know of one other tuner like that, but he doesn't frequent the forums  :smiley:

Your last point is very true.  Everything in car tuning is totally subjective.  Everyone has their favourite brand of suspension, tyres, brakes, oil etc and the same is true of tuners I guess.

I don't dislike my current Stg 1 custom map.  It's held it's own against a Merc A45 AMG and a few stage 2 ED30s, so it's clearly got the minerals....but it just doesn't feel quite as plump and juicy as my old Revo map.
