different ? Power increase alot ? I tried before in my friend rojak 4G92 (with 4G93 head and 4G91 ECU) but the power decrease alot..jerking all.

Fuel mapping between both ECU is different but you can try go to any tuner and check out the error code.

performance will slightly increase and so the fuel consumption

FYi, i already tried plug a 4G93 modded chip ECU into a rojak 4G92 (with 4G93 head & 4G91 ECU )

Power big sux then before..car cannot rev and drag either...i think the mapping not maching so do the injector all...
