obd0 ecu in a crx with a stock crx si motor, im wondering wats it safe to redline to cause i could hit 7. dunno if its good for the motor or not.

 

uhhh.... I wouldn't advise this. Considering its a single cam, and the b16 is dual.

haha I hope you dont think your going to hit vtec with that ecu.

 

only ecu i had didnt wanna spend money on another ecu. it doesnt seem to have any problems just that its sending code 22 and 23. and i dont got a knock sensor or vtec

 

Anytime you hit redline, its bad for the motor. The higher you redline, the worse it is, but honda engine take a good beating. Your engine should take 7500 with no problem and be okay. Im not sure if the ECU will allow the engine to rev that hight though, cause it also depends on the engine. If this is your only car, i would not do this too often cause you might misshift and then you will have no car to drive around in.
