i have a b20 in a EF. i have seen someone on here with the same problems as myselfe. first thing is i bought the motor from HMO online 30xxx miles. i put the motor in my car and now it only revs 2 like 3,500. i have no clue why it does this, i have quad.checked the wires on crank angle sensor. i have checked every wire on the ECU and every wire on the entire motor for that matter....i just need some help....sounds like a rev limiter set at 3,500 RPM...

 

its in limp mode. any CEL's?....take it to someone else to get a second opinion on the wiring

 

CEL's? If not ICM

 

what dizzy and ecu are u using? is the tps good?

 

CRX si dizzy and ECU..obd0 injectors....we went over the wires about 7 times.....

 

u need to be running obd0 ls dizzy and ecu for it to be running right..as long as u r running the ef harness u dont need to worry bout the crank sensor on oil pump...everything is in dizzy..trust me..went through this shit back in the day...obdo dizzy and pr4 ls ecu
