Just wondering if the p28 will run a ls\vtec with out chipping or using hondata (which hondata will come soon after break in period)......or will using a p30 ecu be a better choice since it is mapped for a DOHC.....probably a dumb question , but want a well running engine.....(I realize that the p28 doesn't need a knock sensor but the p30 does) any input would be great since I can't seem to find anyone who has used a p28 without a chip or hondata on a ls\vtec
