check http://www.hondata.com for more info under the K-Series submenu. But here is what Hondata-4 does for the K20A2 in the RSX-S:
"K20A2-4: 5200 VTEC point (necessary if your car has an intake system) and 8600 rpm REV limit."

hondata for the RSX is an ecu reflash program...it remaps air/fuel and vtec engagement point at full throttle only. this is how they get gains while still remaining smoggable...smog centers rev to 2k (corrrect me if I'm wrong please)...so those areas of the maps are untouched from stock.
you have to get hondata's upgrades if you want to get the best bang for the buck. unless, you want to get AEM's PEMS...for about $1000 more you get a totally tunable system, which is nice, cuz you can swap out maps for different tracks if you race (or stock for whatever reason if you need).

A couple of people on ephatch have it and have dynoed it , they did not show any gain just a higher rev limiter. and 3 months ago here in Seattle at our dyno meet a Type S with it kept detonating with the hondata. I need to find out if he got that fixed.
