[s-cars] Chip tuning using piggy back modules

[Tony Guttmann]

Not a single response to this message. Surely someone has some knowledge,
experience or (supportable) opinion?

Thanks.

Hi, 
Has anyone any experience with using piggy back chips, such as
www.perfectpower.com/downloads/login.asp 
who offer support for AAN engines?

I have an UrS4 55,000 miles, with RS2 EM/turbo, Lucas injectors, Forge dump valve,
Samco everywhere, RS2 gearbox, Koni sports, 3" Stromung equivalent, and
am finding it impossible to get ECU chips tuned locally, or from o'seas
by sending dyno charts.

Accordingly, I am contemplating alternatives, and the Perfectpower piggyback
solution, tuned on the dyno while you watch, so to speak, seems a tempting
way to go. The guy who does them has never done an AAN. Hence the query.
