hey, i recently put a 97' B20B in my 1993 civic hatch dx. For the swap I used the stock dx engine and car harness. I also used a 92' integra Ls ecu. When I'm driving and get on it the rev limiter hits in at different times. Sometimes it hits as low as 6200 and sometimes it will rev to 6900. What do you guys think would cause this to happen?

 

I would double check the tach's functionality.

and if it is a stock tach, douubt that same functionality.....

computer controlled, preset, the rev-limiter is unlikely to change


if it's neither of those 2 just chalk it up to the crack smoking.

 

well it does and i dont know why i think my car has mood swings

 

anyone else?

 

My B20 w. the 91 LS ECU does the same thing, sometimes it hits rev limiter @ 6800 and other times at 7200... shows how inaccuarte the stock tach really is...
