Not had a mapped car before, and was planning to get Stage 2 Revo on my 2002 S3 in the coming months, but am slightly confused where to take it.
My local Revo dealer (VAG specialist) isn't equipped with a rolling road, and when I queried this he informed me the car is set up with live mapping on the road, and he steered me to the info on Revo website;
Rolling Roads Explained
Rtech is 1.5hrs away from me, Bill is 3hrs away, which I'd be happy to travel, just slightly confused which is more beneficial now.
Would I actually gain anything from a rolling road, other than numbers?
Quite Frankly the revo's info on Dyno's is somewhat misleading, whilst having a few pertinent points. Worth pointing out Revo dont have a dyno of their own so far as I know.
Their dealers, (those who have invested) may well have a dyno, on which to log and test the car BEFORE a map, and AFTER so the optimum settings can be dialed in, to get the best from the software vs hardware. Its a controlled environment where the car is not being driven to extremely high speeds on the public road whilst looking at a laptop to judge whats occuring. Decent dyno's have full data logging as well as usual vcds/hi-speed logging, so the whole picture of performance and engine parameters can be monitored and reviewed. The Revo code, can then be dialed in with its setting of Ign and Boost. Whilst its adjustable in these two respects, its not adjustable in specific rpm/load points unlike someone making a custom map. If you have revo1 its an inexpensive upgrade to go to revo2 £50+vat + Tuner time £
A tailored bespoke custom map doen by someone who knows the me7 and 1.8t well will always out perform a generic code in my experience.
Beware of many touting "custom maps" however, as there are many scoundrels out there selling their bought in generic code as "custom" where its nothing of the sort.
you get before/after numbers from a dyno, so a "gain" is evident with Data to support it. As opposed someone telling you it "should be xyz bhp" without anything to prove it.
Yes dyno Lottery applies, and few dyno's correlate, but ones which do (with each other) are mine, JKM,RTech ion terms on bhp, and mine reads 16% lower torque figure than JKM,Rtech but match consistently in this respect.
Choose wisely. Its your motor at the end of the day
you will find those who make the arguement against Rolling roads, are usually those who dont have them, and have'nt invested in them. They are a tuning tool.. you get a before and after figure, and the gains are evident for all too see. No smoke and mirrors.
Good luck
Make sure you have mods to justify a stage 2 level of tune also...
what mods do you actually have?
