Re: quick question
The older fuel/ignition ECU's (155, 145 pre face lift) use a Bosch M2.10.x (where x=2 or 3 I think) system - these are EEPROM based and contain information such as rpm limiter, fuel & ign maps. These cannot be remapped - but need a new EEPROM to be blown with modified data.
The later ECU's (145 face lift, 156, 147) have to be programmed with a laptop accessing the ECU directly.
It is just the methods that are different, but at the end of the day the results achieved are the same - modified fuel/ign maps &/or increased rpm limiter.
The term chipping referrs to the first method (replacing the eeprom), and remapping usually refers to the second method. But really they are the same...
