Okay maybe someone can give me an idea of what are things that would cause a b18b1 swap into ej1, not to rev out to the redline?

how far is it going?

It is going to 6k rpms, when it is supposed to go to 7200 rpms and don't know why it is doing that. As soon as I switched to a b-series it has been doing this and no check engine lights are on.

ecu could be bad. if not that, then the dizzy is going out on you

yea sounds like the dizzy

Is there any difference between an automatic and manual engine harness?

i heard that it depends on which b18b you get.
beeing as you have the b18b1 and so do i,
i find it rather odd.
i rev out at 7500 and bounce around that as well,
but my most power is right around 35 or so and builds to the rev.
what i have learned is that some of them that arent ls motors rev out around 65 and have less hp and it the same motor.
im also assuming your motor is jdm like mine.
i found a spec page i can forward you if you'd like to see it.
it has the specs of everthing for every honda motor.
whether its american, japanese, or europian.

i hope that helps. let me know what ya find out.
and if anyone knows about a realiable build for boost on a jdm b18b1 please let me know. well, i guess i need to know.

@ Jaswhy B18b1 is usdm & b18b is jdm, just so you know.

i honestly didnt know, thanks for the info.
so i guess mines a b18b cause i did look and it is a jdm motor.
ok, well, at least i learn something every time i log on to here.

A stock B18b1 redlines at 6800rpms not 7500rpms. I have mine tuned to red line at 7000rpms.
