I run a p28 with hondata(h22a4/ek), and my car feels like it has much better torque than before (even without IAB). People have had fast cars with both....all in what your future plans are.

exactly, you're going to have to elaborate if you want an answer.

the hondata p28, is expensive, but you get what you pay for. I'm using it in my car and the car runs much stronger than the P13. Plus you get to dyno tune and 3 step!!! Save up and go with a P28 w/ S200, thats my advice, and remember to move the vacuum hose on the Iab to a slot on the intake manifold, that way the IAB opens up w/ the throttle, and you shouldnt lose anything in the low rpm band.

or just use the p72 w/hondat, then you wont lose the knock sensor, and the iab's will be hooked up right.

It's actually kinda an advantage if you lose the knock sensor, that way the computer doesn't ever retard the ignition. But yeah it probably would be best for most to use the P72. The P28 was better for me to get rid of the egr and knock.

how is that an advantage, id rather it retard the timing, then blow my engine. there should not be any knocking if the car is tuned right. my egr is blocked off, so if i ever need it, which i wont, i can unblock it.
not saying the p28 isnt a good setup, many use it, p72 is just better imo.

Re: P13 vs P28 (crj_lll)
Can you please educate me, I have an H22 with p28 spoon chipped. What ever that means, from what I've herd its a single cam ecu programmed to run dohc. Its really strong at 5800 rpm vtec kicks in hard, and I recently installed a vafc controller and set the vtec to 5100 rpm and vtec seems a little weaker. Is the vtec band spread out now?, is that why it feels a little weaker. I thought about inquiring into hondata, but I saw the price list damn its expensive. What is hondata ? please educate.

Hondata makes your existing ecu into a programmable ecu. Any program you want, other features to run boost, 3 step rev limiter. Basically it is the Ish' you can take it to the dyno and tune with the S200, much better than just an ecu w/ chip + vafc. You get what you pay for...

Well I've heard of instances where the P72/P13 will detect faulty knock. Which means pulling timing uncessarily. Look at 4bidden. His knock sensor went "bad" and it ruined his car's performance.

Re: (precord96)
So what your saying is that I will not need my VAFC correct, because they will utilize my ecu and there programming right?. Are you running Hondata?, I got an EG with H22, just trying to utilize all the potential power.

That's correct. The Hondata setup can do everything your VAFC does and more, in a better way. Rather than altering the signal from the MAP to fake the stock computer into giving more fuel, you can use the correct signal and simply change the fuel amount at that portion of the map.........
And guys, the knock sensor is crap, the ONLY reason to get a P72 over a P28 is for the IAB control. I'd personally prefer to use one of our P75's, that way there is IAB control but no knock.
The knock sensor is disabled (aka not allowed to alter timing) above 5500 RPM anyways regardless. Please enlighten me as to how a knock sensor that is disabled over 5500 rpm (the part of our powerband where the real power is made) and can only alter the timing by a small amount is going to save your motor and justify spending another $50 to get a different ECU? Get a P28, you'll never miss the 5-8 horsepower you're losing in the low end anyways.......
I'm gonna go write up a whole post just for us prelude guys on the different ECU options available and what/what not to do/buy......
