ecu question

hey everyone i have a jdm b16a in my 93 coupe ok i just found out my ecu i am running is a p28?? ive been told that is a sohcvtec ecu and that mine should be a pr3? ok this prolly explains why my motor wont rev past 7600 rpms in each gear but what other kind's of things could i be losing by having this ecu in my car rather than the pr3??? any thoughts are welcome... laterz

i belive the other ecu also is set up so it delives more fuel...n a higher top speed...

can someone tell me how the p30 ecu does on a b16a engine? if anyone has used a p30 let me know how it feels and when does vtec engage and wat does it redline at... thanks

bump can someone please tell me how a p30 will work on a 5 series b16a motor when does vtec engage and when does it redline also what is better a pr3 or a p30?
