Ok so i put a jdm d15b in my crx dx. I did the dpfi to mpfi swap and am using a obd0-obd1 jumperharness with a virgin p28. I hardwired vtec, and the iacv. the car starts and runs but doesnt rev past 4000rpm. Ive swapped 3 dizzys into the car, and two diff p28s. Also tripple checked dizzy wiring everythings fine, i have all grounds hooked up, thermostat ground is tight. This thing has me stummped, ecu is giving a code 19 auto transaxle its a 5spd car, auto ecu. Never had a problem running a auto ecu before, but im worried that i have no o2 sensors wired and its not throwing a code. I hardwired the IACV and vtec wires.. still no difference. any ideas?
