Hey guys it's been awhile been working my *** off!!!! But, anywayz i just had my motor rebuilt with ctr pistons. (2000 si) Every now and then it will act as if it has a rev limiter at 6500 rpm????? Any answers or suggestions cause iam getting tired of resetting my ecu. Also i needsuggestions on the next mod either hondata or cams ( stock head work)!!!! Sorry was so long!!

 

is it throwing any codes?... what octane gas are you using?... maybe possible detonation due to the higher compression

 

It's running a lil lean but no sign of detonation(spark plugs). I run 93 with 2 gallons of 100octane. It throws a oxygen sensor low voltage signal.
