I have a p28 ecu for my d16z6. And I have a chip but not for a p28. Its a p30 chip, witch is for a DOHC VTEC. A B16 I believe. Do you think it would hurt to put it in? VTEC: 5400 RPM REDLINE: 8800 RPM KNOCK SENSOR: DISABLED (Don't have one) SPEED LIMITER: DISABLED I don't even rev it past 6000 rpms. Don't dear with stock internals.
