Chip quiz for the old timers
These photos are of Michael K's ECU. Looks like his 08/92 build date 93 S4 was chipped sometime in 1995. Only the fuel/timing chip is labeled and all it has on it is FB20. It is sitting on a daugther/scrambler board. The boot chip is NOT labeled. The MAP is still 250 kPa (2.5 Bar) so I am thinking TAP/Hoppen or MTM Stage 1. Anybody remember what these chips really are?
