:confused:
alright i screwed up like usuall heres my dilema i did the dx to mpfi swap onto my crx i have a d16y5 vtec e motor in my crx at first i had a lag issue problem anything over 3/4 throttle and the car would fall onto its nose it wouldnt stall but would just slow down i went to axiom they said to upgrade the intake and fuel pump (i put an si fuel pump in) so i did
i did the swap onto the car following everything step by step that i got off line to do the swap word for word and tagged all my wires in color code so i knew what was what i took the b2 wires and b10 wire and depinned them didnt cut them but depinned them and moved them to b10 and b12 like i was suppose to i cut c1 & c2 and spliced them into b11 & b12 i connected c1 and spliced it into to b10 and c2 and spliced it to b12 making sure to leave everything connected
i attached wires to c1 & c2 and made sure to mark them and run them into the engine compartment like i was suppose to i aslo cut wires to a3 & a7 and ran them into the engine compartment as well i did not however hook up the wires that i cut off @ a3 & a7 i left those two wires floating and taped off under the dash
i extended all of my wires at the tps and eacv i followed the instructions on how to hook up all injectors and i am running standard si injectors and i depinned one wire at a time on my dizzy plug on the dx dizzy and transferred them to the si dizzy plug one by one so the only wires i cut were the ones under my dash and a couple under the hood and followed the instructions on how i was suppose to do it
since i have done this swap i have had problems the car starts up and runs fine my si dizzy is also notched for the vtec head but when i revv up on the car it tachs at like 3500 and starts to back fire and the car is puffing black smoke so obviously a sign of me running too rich i have doubled checked all of my vaccum lines and they are all hooked up
i am just wondering if i screwed up somewhere with the wiring or what any one have any suggestions or ideas be greatly appreciated axiom said they would charge me 65 to diagnose it but this is my backup car and my daily driver since my wife is always driving the truck so i need help and i need it asap some one please help me out thanks chris
already did switch them back to the regular way it didnt help i also swapped the two wires around on the dizzy plug all it did was make it so it wouldnt start i have tried just about everything the only thing left to do is
A: swap stock fuel pump back in
B: double check all my wiring again
C: switch back to the dx intake again ( which i really dont want to do unless i have to )
not sure i have a code for 4, 14, 20 and thats it i cant find my book at the moment so trying to look the codes up
ok just found my book it say this for the codes
4 is tdc crank sensor which is one of the codes that i also had while running the dx setup
14 is electronic air control valve
20 is electric load detector
alright reset the ecu and the codes popped back up i change out the ecu to an automatic si ecu and the codes popped up there as well drove the car and wont revv up past three it seems that around 2000 to 3000 it seems to start dumping gas thats what it seems like
i have already tried adjusting the dizzy i have changed out the ecu and i have also double checked my wiring what else is left anyone with some suggestions
