i recently put an lsvtec in a 93 hatch it has a p30 ecu i was just wondering if anybody else has ran this ecu or should i justy get a chipped p28 also idle is surging (going up and down) could this also be caused by the ecu?

 

I pray the P30 is chipped, the P30 is designed for the B16a, not enough fuel and the ignition maps are not right for your setup.

BTW chipped, the only difference between the P30 and a P28 is the knock sensor ability in the P30.

 

thanks
