b20 hitting rev limiter @ 5500, p75 ecu, no CELs..HELP
me and my frined just finished installing his b20z into his eg. it runs strong, no check engine lights (had to modify o2 sensor but no biggy). all in all im VERY happy with how the car performs.
NOTE: we are using the obd1 LS ecu (p75)
when it first started it had a cel, o2 sensor (41), and it was hitting the rev limiter at 5500.....i fig the o2 sensor was the cause for the rev limit problem. well today i fixed the o2 sensor problem (if u need to know how plz feel free to PM me). well take it out for a spin and it bangs the rev limiter at 5500 again???????? there are no cels, eveything is wired up......i fig his tach may be off?!?(its out of a civic ex)
if anybody has had this problem plz let me know, and if anybody knows how to fix this feel free to tell me ur secrets.......pretty plz.....w/ sugar in top.
thx

Did you reset the ECU after making the O2 fix? Most of the time the ECU sees the new change (fix) abut it's still stored the CEL. If you haven't tried resetting the ECU, do that then see if it changes anything.
