did the swap, the car is running but the only problem is this guy sold me a broken (p28)ecu, so just to make the car run i just put a ex (sohc) ecu in it...but the rpm cut off at 3500 and i have to switch gears...so i bought a p72 ecu wit' mugen chip, but it does the same thing the redline get cut off on 3500 rpm , what should i do to fix this i dont wanna spent no mere money to get this car running right.....helppppppppppppp...

 

spend a little more cash and get your ecu remapped from any tuner shop familiar with hondaswaps.
