jdm p30 ecu question!

I was woundering if the A “jdm p30 ecu” is a good ecu to buy. Or should I not get a jdm ecu?.. And does anyone know what the redline limiter is and when the Vtec kicks in on them… Thanks!!

the problem that i had with my jdm p30 was that folks that chip ecus hate do do them since the conponents are much smaller than those in a usdm ecu. vtec kicks in at 6000 rpm.
