Hi there, i am from asia driving a civic VTI eg6 which runs a DOHC b16a2 VTEC engine. Recently, i have met a problem on my Rechip p30 ECU with Jun stage 3 chip which causes a continuous CEL on. After replacement with another so call JDM P30 ECU with mugen chip. The car works perfectly fine. What interest me is that this ECU has no indication of any P30 reference code on the cover. It has the shape of JDM(square ECU) with the following codes at the cover and a licensing MUGEN sticker Code XG6 and N00002 was indicated instead. 1. Can anyone enlighten what ECU is this as i have try out several website but in vain. 2. Replacing the Jun stage 3 chip on the defective p30 ecu could it work again? As i have no problem starting the car but the CEL with continue to light up. Hope some bros can help.
