He is correct, basic answer is no it does not have IAB control on a p28 ecu. With per say like an s300 hondata in your p28 though you could wire an output to the control solenoid to open the IAB's.

Or you could remove them all together, depending on your setup it might not give up much low end and would actually help your peak hp.

my only mods are i/h/e....short ram, 4-2-1 header, and magnaflow exhaust....i was jus inquiring the losses of leaving them in but closed....or removing them all together.

Hrm so pretty basic mods, and sounds like no need to have any management like an s300 or something easy to work with that could trigger them to open off an output signal.

As far as leaving them in or taking them out... well its a trade off either way basically. If you leave them in closed they you will make better low end torque power but choke out the top end power a bit. Visa-versa if you remove them, your low end torque will suffer a bit and your top end will pick up a small bit of power.

Might search honda-tech or a large national forums for people who have similar setups with them removed to see what to expect.

i think im gonna search for a p72 cuz i want low end so i need them active....but i also read about a p72 baseform on a p28 tuned with uberdata and the guy had complete function.
