JWT ecu help

[sportbikedude]

i have a jwt #62 ecu tunned for z32 mas, 72# msd injectors. the guy i bought it from said it was for 550cc injectors. well after installing them i realize i need more like 740cc.

so i figure i could use some from deatch works like my 550s. i e mailed him and he said his injectors wont work with the jwt tunes. anyone know this to be true? if it is true now i gota replace my rail, injectors, and wire plugs?

also the ecu tag says "must use dropping rest." what does that mean?

thanks for any help you guys can give

Just like it says you need at add dropping resistor to correct the power to the injectors, If the program says 72# injector you need to use that.....
