I just got a mugen ecu in my 90 crx si, the only mods I have are injen cold air intake and DC headers. I was just wondering whats an ideal redline for my crx without hurting her too much? thanx for any comments... oh and I got it for fifty bucks!!!

 

it isn't a real mugen ecu, its actually a varient of mugen ecu specs, burned onto a eprom and put in a stock ecu. has for rpm's id say stock since oyu don't really have anything mod'ed internally.

 

I would only rev to the stock redline. The car won't make power past that since you have very minimal mods

 

exactly!!!!!!!!!!!!!!!!!!!!!!

 

16,250 rpm unless you have naaawzzzzzzz then you can easilt go to 19,000rpm!!

j/p stock is all you need! no higher waste of gas.

 

lol
