yap, exactly as you said
a few months later I got confirmation on a Czech website. (google language tools rule!)
BTW here are the locations for the 1.8 16v clio:
RPM Limit : 4313 Hex (16 bit value)
Injection Map(Relative) : 407C Hex 8bit 13x9 RPM vs MAP
Ignition Map : 4007 Hex 8bit 13x9 RPM vs MAP
there are a few good books on the subject in the UK ebay. haven't bought them yet, cashflow goes to the car
PS: strong microelectronics background is heavily advised.
