i have an lsvtec in my 94 hatch w/ 12:1 comp, dc sports 4:1 header. and some other stuff everyone says it doesn't feel like it should is htere any diff in a chipped p38 and a p72. has bigger fuel and ignition maps 5k vtec, 8k rev limiter ne diff

 

if the p28 is not programmed specifically for that engine they will both suck.

It doesnt matter what ecu you use, as long as it is tuned correctly for your motor. The P28 is preferible because its easier to find, looks for the least amount of sensors, the P72 has knock and IAB

 

tuned or not should vtec be noticable when it engages. it feels kind of weak and iknow its not tuned but you can barely hear it kick in either
