    ok well i was wondering something about my car what is the best ecu to run with a jdm b16a right now my car will red line around 8600-8800 i have a p2t ecu not sure if i could have a better one that will help me accelerate faster because its not as fast as some other si's i have seen.

    Not enough information given. Different ECU's work better for different set ups. If you have basic internals and a few bolt on's.....I am certain that the power band is flat or diving down at 8600 rpm's.....not making power...actually hurting a 1/4 mile time b/c you are wasting time at horsepower that is flat or decreasing. If you don't have different head/cams/injectors/throttle body or turbo....you would most likely be wasting any money if you were to get another ECU. A different ECU will not give a basic set up anything worth doing.

    If you can rev that high....it must be a mod'ed ECU b/c my P30 only revs to 8100 before rev limiter comes on. So you could have a bad set up (robbing power) if you have basic mod's. Air/Fuel ratios could also be way off. You're best ECU for a bsic mod'ed set up is a STOCK P30 or in your case (OBD2)...the B16A2 P2T ECU

    find out if you do or don't have a built head. if you don't, build it and get a p72 off a gsr.. that way you get more power at high rpms

    If I was you....and wanted to know whats up....I would start taking stuff apart or take it somewhere so they can check. Sounds liek something is wrong if another B16 in the same shell walked all over you. well...its a DX but its not that much lighter...not enough to take a walk on you.

    You can also do a leak down test...and check compression (first) this could also be a problem

    The compression reading #'s are up to debate in my opinion. Some say stupid #'s (yes I said it) like 210 across the board. And many others think these guys who swear by some 200 number aren't doing the test right. I have always been told somewhere in the 180 range is good.

    Never the less...the important thing is that they're somewhat up towards 200 and that all cylinder compression #'s are within 5-10% of each other.

    So 182-180-184-182 would be perfectly nice. Now you have this mystery 'built' head so #'s could be different but the point of a compression test is to see if they're all around each other's compression #'s....in sync and shit lol So do it and let us know the numbers. Its best to disable the fuel and leave the spark plugs in the cylinders your not checking at the time. And make sure the car is as close to running temp as humanly possible (close cuz its hot shit to work on). You can unhook the ECU to disable the fuel then just give it 10 seconds of crank for each cylinder...write the # down and go to the next

    OK thanks man i took off the valve cover but i still unable to tell if the springs are changed or anything take a look at the pics i posted above i was told in yv-tech to check the compression by 3 cranks :S but i never remembered the range it should have been on.

    Can't tell whats up with that head by pictures you posted. You need to take the cams out and
    check them out. I might be able to tell what cam it is if you send me pictures of the end of the
    cams but if I cant...hopefully someone here will be able to tell. If you don't feel comfortable with
    doing the work...either leave it be or take it to a shop that can tell you whats up.

    Just do compression test and tell us the results.

    If the compression test turns out good, how is your clutch, you can loose a lot of time during accelearation if your clutch is slipping. either way good luck, neither one of these fixes will be cheap or easy.
