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?

 

maybe good old fashiond inaccurate honda tachs

 

i don't think that its the tach. anybody else have an opinion?

 

bump

 

my guess would be the tach...sometimes mine is accurate, sometimes not. i have a VAFC2 and the furthest i've seen it off was ~400 RPM

 

i'll check it but it has never been wrong before

 

do you think it could be the ecu. I'm runnin a 92' ls. should i try a 94'.

well my redline with a 95 ls ecu seems to be 6800-6900 rpms wit a autometer tach

hey btw do u have any fuel leaning problems during WOT between any certain rpms????? causei do and its pissing me off

 

i don't have any fuel problems my rev limiter just changes its mind all the time

 

My tach is usually off between 300-400 RPM's
