Unless you are going with a fully built motor and turbo setup, Hondata should be fine (based on what I've heard from many people, never used it myself). But if you are going to be changing cams, using radical intake design, fully built bottom ends and huge turbo's, the AEM is your choice. Basically the AEM is FULLY customisable in EVERY function the computer does. It can datalog many things and do them many different ways. Want to see what happens when you go past 50% throttle in 3rd gear above 60mph? You can set the datalog to only start once all three of those parameters have been met. It gets ALOT more complex than that.

Now, from what I understand, Hondata, while working quite well, its FULLY adjustable like the AEM. Its mainly used for basic adjustments of fuel and timing tables, injector size, switching to a GM 3 bar map sensor (so you can tune for up to 30psi).

So based on what you want to do with the car, sounds like Hondata is the choice.

Another huge factor to consider is local support. John (Vapor) is very familiar with Hondata and has a dyno to tune it on. Nobody in the area is really running an AEM yet, so you don't have anyone to turn to for help (trust me, you WILL need it with the AEM). This is why I went with Electromotive. My friend Allen Moore in Plant City is a dealer and has tuned them on everything from a turbo rotary powered Porsche 911, to a Subaru powered airplane.

 

FYI, you can get the AEM for about $1400 new (my friend bought one brand new off Ebay for $1k). but Hondata is still cheaper. Also unless you want to buy a laptop, you're limited in what you can do anyway, so Hondata is better there too. I realize Hondata requires a laptop, but my point is that unless you've got a laptop you can leave plugged in constantly, you're just going to be changing basic stuff, which the Hondata will do wonderfully.

Oh, and 22 psi should be possible, but it will be mostly heat. Some of the 2.3 Turbo guys run 25 psi, and they make more power, but inlet temps sure are warm then.
