is the a site or if some one on here will know off the bat each ecu where vtec comes in.
i have 3 ecu that i want to know each one.there all obd1 and not chip but the p28 is chip if matter

p61
p30
p72
for the hell if it p28

 

p72 is 4800 p28 is 5500 or 5600 p61 is also 5500 or 5600rpms if your doing this to change ur vtec point on a stock car dont bother

 

kinda i just want a ecu that vtec come in at a longer rev cuz i hate quick vtec

 

You can't go around swapping around ECU's just to get a different VTEC crossover point. The fuel maps will all be different, causing your car to most likely run like garbage, if at all.

If you're not happy with the way the car runs now, you need to have it tuned, and perhaps chipped or with something like a Hondata or other engine management.

Oh and the P72 VTEC crossover is 4400 rpm, not 4800.

 

i hate chip ecu and plus my motor is bone stock so i should be good
