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

TO START AXIOM OR WHAT EVER ARE very stupid. I run 17psi on dx fule system. second of all switch the tps wires

convic23

i 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 )

help with some more suggestions

and what do you mean you run 17 psi with stock dx fuel pump whats the difference between a dx and si fuel pump anything or what but its obvious that i am dumping too much fuel into my engine at the moment since it is puffing black smoke any help is greatly appreciated thanks

1 black smoke is burning oil, blue is gas
2 fuel pump is fine
3 get car running the way it was falling on its face
4 check your ecu for codes.

Zeniceguycrx

nope
My shop does emmisions repairs and diagnostics all the time. you have a car with a leaky injector and then fire it up after a day and watch what happens...........blue smoke baby

see thats the thing i was running the dx setup when i did it and still had the dx fuel pump in which i had a feeling it was going out so i replaced with the si fuel pump that i got out of the yard and before i did the swap it was puffing white smoke which i was told cause it was lean now its puffing black which is what i am told is rich so that whole thing is new to me and i have no way to find out how much fuel that i am putting to the fuel rail thinking that might be part of the problem though 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

the only thing that i can think of is the two wires that i cut off at the ecu @ a3 * a7 those are the only two wires sitting under my dash that arent hooked up i mean the two that you cut off i attached wires to the a3 & a7 and ran them into the engine bay so other than i am so confused and frustrated
