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?
 
i have all vacuum lines plugged in properly, also tryed running the engine with vacuum lines unpplugged. I did a full wiretuck but the only thing i really had to mess with was the dpfi-mpfi swap but i pulled the dash back out last night, gonna go through with a multi meter and see if i cant get this thing fixed, everything was soldered and shrink wrapped
 
open the ecu and clip rp18 and rp17 out and go to radio shack and get a 0 ohm resiter and solder it to rp18 place. that will get rid of the nuetral switch on the auto ecu and convert it to a 5spd ecu
 
all fixed.. so i got sick of messing with this car, so i tore everything apart and started checking all the wiring with multi meter. I came across the the dpfi to mpfi write up i used and double checked everythng, realizing that the chart read. Inj1. Inj.2 Inj.3 Inj.4 and didnt realize that i had wired the injectors like this.. Meaning they were backwards, As The dizzy side counts inj.4, inj.3 ect.. Thanks for the advice and how to convert that ecu to 5spd!
