    i recommend running the jdm p39(no knock sensor) or the usdm p14. i remember when i ran the f22ax ecu and the car felt sluggish at mid-upper range. when hmotors finally sent me the right ecu, it felt so much better. but then again, FushigiRES will probably come up with a reprogrammed ecu tuned for his motor

      but if you used the F22aX intake manifold wouldn't it be just fine to run the F22aX ECU? cause the intake mani from the F22B may use the p39 but the F22aX mani won't

        Sounds correct to me!

          what the heck?

          if you run the f22ax intake manifold on the f22b with the F22ax ecu, i will slap you over your head.

          Sounds correct to me!
          USing the aX manifold alone would be downgrading. let alone using the f22ax ecu. IT will pull so much harder if use the p14 or p39 WITH the F22B intake manifold.

          the only thing i can come up with on this, is because of the IAB but who cares?

          The ecu has nothing to do with what intake mani you run, unless you have IABs on your intake mani and you want to keep that feature. i personally dont have my IABS hooked, i just have them stuck open.

          if you use the f22ax ecu on the f22b it wont let you rev has high as it should, it will top out at like around 6krpms...

            The F22AX ECU will let you rev higher than 6,000 rpm. Who ever said he was going to use a sinlgle runner IM? The Dual Runner IM came on some F22AX's too. And BSTDCB7, if you are planning to run the Dual Runner IM, use the IAB system. Keeping both runners open all the time kills the low end so in that case you would be better off with the F22AX single runner IM.

              well I have an F22a1 but if it owuld be better to run the A6 manifold I can get one with the ecu and all.

                The F22B/H23 manifold is better than the A6 manifold... it has larger diameter runners, slightly different length runners and the upper plenum is just larger...

                the A1 single runner manifold can be ported out and be more effective than the A6 manifold...

                but left stock, the A1/A4 mani will choke the F22B past 4200-4800...


                The ECU has more to do with the engine than the manifold like juan said...

                I've run all the Accord ECU's on my F20A and even the P39 before I got a PT2 and the only thing that came close to the PT2 was the P39... the PT3 & PT6 were decent for driving and mileage but not the best for performance...

                If you don't care about eeking out every little last drop of power then run an F22Ax manifold and/or ECU and be satisfied...

                This is kind of like the A4/A6 EX 4-2-1 exhaust manifold debate... if you don't care that there is a part out there that will pick you up a proven 2-4 hp and are happy with that part that is merely "good enough" then by all means... do it that way...

                  Kewl....there's your answer BSTDCB7. I could only speculate the answers to the ECU question because I have yet to complete this swap. Thanks for the great explinations Zigen...

                        well thanks zigen, I appreciate the information. Now since the p39 is SO hard to find then running the p14 with a knock sensor is gonna choke the motor ne ways right or wrong? I am gathering AS MUCH info as possible before doing this so it goes smoothly and I will get the most out of this.

                          who is this guy?!?! don't listen to this guy about the intake manifold information...it's not like he has a 100 of them lying around by now along with heads and been playing the role of the mad scientist

                          all i have to say is a P&P H23 manifold ownz A1/A4 & A6 manifolds period

                              p14 w/ knock will work redline @ 6800 rpm.butterfies opens@ 4300 rpm
                              i cannot stress enuff how important the knock sensor is to optimum performance. i run this set up on the wag,and i love it.
                              their is ALOT of good info on the web site. do your homework,you'll learn. good luck

                                Yeah why the heck would it Choke the motor with a p14?
