    i have JDM SIR II B16A engine with GSR P72 ECU.

    is it ok for engine? because i hear vtec working on after around 6000 rpm.(dont know exactly when...)

    however i got z4 ecu which is 99-00 civic si ecu.

    is it better for engine? if not, what would be better for my engine?

    one more question, people say p27 is good. is it true?

    get the ecu thats for your engine, the p72 will cause you to run to rich

    werd. id recommend you find a p30 to run that or get it chipped with a map for a p30 (kinda hard to find one made for the p72, luckily, its not to hard to convert the p30 map over to the p72 fuel settings).

    GOD DAMNIT READ WHAT I POST.

    the correct ecu for a b16a2 (from a 99-00 civic si) is a p2t.
    the correct ecu for a b16a3 (del sol vtec) is a p30.

    if your car is obd2b, go with the p2t, if its anything else, convert to obd1 and use the p30.

    what year is the car?

    obd2b is 99-00. if youre car is any other year, use the p30.

    do you have a jdm b16a or do you have a b16a2 (meaning usdm)?

    the p72 is a gsr ecu, meaning built for a taller deck and a longer stroke. that being the case, it requires more fuel to run, and if you try and use it on your b16 itll run like crap.

    the p72 will work, but itll run like crap. get a p30 and call it a day.

    yeah.. probably i gotta get p30 because when im running, vtec doesnt work after 4500 rpm... it works after around 6000 rpm.
    u know where should i get p30?
    should i get just ecu or ecu with jumper harness stuff?
