hi i just did a det swap 98 avenier,iam useing right now the bb ecu,when iam in fourth gear the car seems to hit the rev because at 6000 rpm the car shut back and i lose boost. i have to change into 5th before 6000 rpm on 4th. other wise i get cut off,does anyone else with det bb ecu have this?.....
what is the top speed on bbecu,i have a 91 se-r.

the rev limiter on japan engines are like 114 mph or somewhere around there. So unless you modify the ecu you'll have to deal with that problem.
