Same really but Aud S4 B5, ive got to the stage were i have my own bespoke stage 1 map ready for testing but require a AFR Guage/reader 1st, its taken me around a year to get to this point, i use galletto 1260 with ebay cable reprogrmmed to work with galletto and tunerpro and winOLS and i have gen VCDS (VAG diagnostics) for logging with.

There's heaps to read up on here and is a welth of knowledge but it wont be givern out, you have to work to find things out

Not to clued up on programs but tunerpro is free downlaod and lets you see the maps edit them etc but you need a .bin from your ecu which is the easy bit depending on your ecu then you need a .xdf which is like the layout with all the map files in there.

Kess V2 is the choice for chip tuners, i was looking into starting a business doing chip tuning but your just selling on someone elses *possible* crap generic map.

There is so much choice out there but i got the cheap/free stuf to get me into it as i simply havent got the money to go and buy the all singin all dancing stuff though half the time the cheaper stuff is better, just because one company has really good advertisement dosnt mean that there equipment is the dog's dangle's

Best to get a 2nd hand ecu and play around with things then if you knacker it its no biggy, the best way to learn is by doing

It may even be cheaper to buy an old doggy diesel and play with that.

True true. I will look into it.
