hi again, im back with the same isue. this z4, the ecu's speed limitor. keeps cutting in at around 116/117mph. i dont want to realy chip the thing but, is there anyone who nows what part of the ecu is incharge of this limitor. if so could i change the part from my uk ecu. thay both look the same to me, even the numbers are. every thing else is ok, even down to the fuel. i just use 97ron fuel. but this limitor. any ideas. basicly ive got a uk 95 but funning a jap z4 ecu.
