integra ecu help

[bkou]

hi guys, i just bought a 2000 integra with a b20 in it. check engine light is on because the mobilizer was taken out of the ecu and it not running a o2 sensor. so i swap the ecu to a obd1 p75 ecu with the jumper harness so now the check engine light is off. but after i swap the ecu, my car will not go pass 6000 rpm. isn't a ls ecu suppose to redline around 7200 or 7300 rpm? is there a reason why it wont go pass 6000 rpm?

Sounds like either a Bad ecu or you could have a automatic one

hmm thats odd, so u have an obd1 engine harness, with an obd1 b20, and an obd1 p75 correct?
