So here is a question that may start a riot and with Wayne in this topic it could be fun, if it's already been done to death please tell me to piss off
.
I really want to map the RS3, everyone says APR but..... With APR being an American company what's their real life experience of English fuel and tuning ability to deal with the difference? I, in no way doubt their tuning prowess and capabilities I am just curious as to how they get round this issue. Do they road test their maps in the country of sale using the available fuel to the customer and in real time conditions before sent into the public domain ect?
Are APR maps a full remap of the complete suck, squeeze, bang, blow procedure, ie increased valve timing to compensate for the increase in fuel pressure, inlet pressure, exhaust pressure and EGT's or is it a case of, up the turbo pressure and increase the fuel as we see so many times with tuning box's and 'remaps'. So many times you hear of complete head failure due to an increase in fuel and boost?
I would also include Revo and any other on the day remapers into this, as a company that can remap cars on the day of a show by a simple flash of the ECU with no on road/RR testing or driving results to me seems foreign coming from a background of remap road test, pull over and tweak, drive and continue until both parties (tuner and customer) are happy with the end result. Spending £850 for a simple ECU flash is out of the question for me until somebody can tell me otherwise . The problem is every car is different.
Which then leads onto the question. With an English based Audi specialist tuner like MRC who have years of experience on home ground, with great results (from what I can see) on their own maps be a much better choice?
They have their own map that is then tweaked and refined as a RR takes place and the car doesn't leave until they are happy with it (from what I can gather). Simply just doing a RR before and after tells no truths about the behaviour of the map, just the figures achieved?
