:rofl2:

Be very careful with the raised redline. You're playing with fire.

:icon18:

Ah, didn't notice that -- thought OP was in Japan.

Well, lets see;)
I wonder how do you know that if no one has installed JDM ECU before me?:rolleyes:

Because the raised redline isn't unique to that ecu. More than one person here has blown up a motor because they were running a raised redline. The brand of ecu has no bearing on the fact that the oil pump internals self destruct at high rpm.

I see. Thanks for advice, however I'm sure that IMPUL has gone through that, and they wouldn't release those brains without being thoroughly tested.

Because race car :icon17:

Ok. Good luck with that. Unless they swapped out the oil pump for something more robust, they've done nothing to prevent the issue. And you give aftermarket parts manufacturers and tuners way too much credit. Just because it's JDM doesn't mean it's perfect.

If I were you I wouldn't spend a whole lot of time in that part of the tach.

Thanks.
Gonna find how to improve oil pump internals. Any thoughts? ;)

There's a Nismo oil pump with billet internals, or just go with a dry sump. Either one is probably overkill for a NA setup since you're past peak power at 8k anyway.
