Trying to find a new ecu

[watson-the-da]

hey CI, im looking do buy a new ecu for my obd1 integra with a swapped b18c1, i found a p28 and a p72 ecu from HA Motorsports, im not sure which one i should go with with, this is my first ecu i have had to buy so im looking for information that can help me.

also the p72 says it has IAB funtionality, what is this?

IAB is the secondary butterflies in the stock intake manifold. The P72 is the only ECU that has the hardware to operate them. If you want them to work you'll need the P72. If you don't want them or are going with an aftermarket IM. you can just get the P28 and have it socketed and chipped with a P72 map written on it. This is assuming the motor is internally stock and doesn't need to be tuned.

The P72 has two advantages - 1.) it has IAB control, 2.) knock control.
The IABs are stupid and the knock control is ineffective.
With that said P72s usually go for a premium.
