anyone running programs from hyperducktuning.com or got an ecu from them? which ones are you running? and what do you guys think?? i got my p28 from them and i got a couple programs...they are for my d16z6 in an ef...im currently running j's racing program..but i have no idea what the specs are on this chip...anyone know???

 

i believe the J's Racing ECU chips have two programs compatible for your ecu. one has a Vtec crossover at 5700rpm and redlines at 8800rpm and the other at 4400rpm and 9100 rpm's (although this one seems pretty inefficient)
