1999 T uk car 3 plug or 4 plug ECU ?

Hi All, looking for clever people to help!

Does anyone know if the 1999 ECU will fit a 1998 car?

What is a Z4 ECu?

Can you just swap Ecus to increse engine boost/power (even if it risks the long term engine health)?

Z4 is an early yellow 4plug ECU for cars up to 96..................

98 cars have a yellow 3plug ECU and the 99 cars are different again..........

at your age (99 on) a remap coutesy of ECUTEK software would be my recomendation - around £650inc.........
