Most people will tell you that to sell you on something. The P28 is the stock ECU for the 92-95 Civic Si and EX. Most people reprogam them to custom specs for DOHC VTEC applications, probably your case due to the lack of a rev limiter and higher VTEC engagement. If the motor is stock as in cams and intake manifold you would be much better off with a stock 94-95 GSR P72 ECU.

Yeah either that or have someone program you a new chip for the P28 that will run your motor. However you may want to look into a few different options for activating the butterflies in the intake manifold ( RPM switch, etc...) I guess it depends on how much money you have to spend cause OBD1 GSR P72 ECUs are pretty expensive in comparison to chipped P28's. I can burn you a stock program for cheap if that's the route you want to take....

You can add IAB control to a P28. Search on http://www.pgmfi.org (Library) to found out have to do it. It will cost you like $2 in parts. My tuning P28 has IAB control.

Yes I know you can add IAB to a P28 I've been a member at PGMFI for about 3 years... Adding IAB to a P28 also requires more than just $2 in parts you need a considerable amount of experience working with electronics and a good quality set of tools (temp controlled soldering iron, etc.).. You also need a new chip burned that contains the code to activate the IABs........
Since not everyone has these sorts of things I was offering a more common alternative...
anyways.. that's all...

No need for setting up the iabs since he's running the skunk2 IM. Basically, in your case, keep your p28 but run a different program...something thats more appropriate for the mods you have done, whatever that may be.

I understand, there is always more options. The more people know about them, the better decision they can make.

Re: ecu question? (smiths54aub)
depends what year p72 you have. Since your currently running th ep28 (i'm assuming), that means your car is a 92-95 civic/integra right? If thats the case, you'll need a obd 1 p72 or a p61 GSR ecu (i have one for sale right now ). Basically any obd 1 ecu will plug directly into any 92-95 civic/integra. obd2 (either version) will not plug into an obd 1 stock harness. There are conversion harnesses where you can run obd2A-1/obd2B-1, obd0-1, obd 1-2. You'll want to stay obd 1 either way in the end because of tuning purposes. with all this said, stick with the chipped p28 becuase your running a skunk2 intake manifold, meaning no iabs on the gsr motor anymore...that means you probably wouldnt want to run a p72
