cloc007 Posted November 18, 2006 Share Posted November 18, 2006 i have 91 dx hatch and im doing a dpfi to mpfi conversion but cant find an si computer does any one know if i can use a 92-95 dx computer or a 90 -93 integ computer for a sub i also have a del so intake manifold will this pose as a problem Link to comment Share on other sites More sharing options...
cranny Posted November 18, 2006 Share Posted November 18, 2006 than youd have to obd convert your car. all you need to do is change a few wires for the extra 2 injectors. the ecu in your car can run MPFI. here ya go my man.

cloc007 Posted November 18, 2006 Author Share Posted November 18, 2006 thanx but what i really wanted to know is there any other ecu i can use besides si 88-89 teg like maybey 90-91 teg Link to comment Share on other sites More sharing options...
cranny Posted November 19, 2006 Share Posted November 19, 2006 why though if yours wil work? Link to comment Share on other sites More sharing options...
cloc007 Posted November 19, 2006 Author Share Posted November 19, 2006 why though if yours wil work? so besides the four wires for the fuel injectors do i still need to run c1 and c2 for the distributer Link to comment Share on other sites More sharing options...
cranny Posted November 19, 2006 Share Posted November 19, 2006 i posted the differences right there , read them find whats different , make it so , simple as that honest to god. Link to comment Share on other sites More sharing options...
cloc007 Posted November 19, 2006 Author Share Posted November 19, 2006 i did all of this and the car just cranks and i double checked everything now do i need si ditrib and computer cause for the pm5 it does not have crank sensors at b10 and twelveB9 B10 B11 Green/Black A/T Shift Position Console Switch (Drive) B12 and thats the pm5 now th pm6 looks like thisB9 B10 Orange Crank Sensor B11 Green/Black A/T Shift Position Console Switch (Drive) B12 White Crank Sensor Inside car @ ECU Pins B10 and B12 are empty. Unused pins can be taken from B2 or B11. Some models have a wire located at B12. 1. Cut orange and white wires off at C1 and C2 and connect them to wires added at B10 and B12. Orange-B10. White-B12. Leave enough wire for next step. 2. Run wires from C1 and C2 (direct ECU connection) into the engine compartment. Label these wires for later use. 3. Cut wires at A3 and A7 leaving plenty of wire. Run these wires into the engine compartment and label them for later use. Before installing MPFI manifold TPS and EACV plugs are too short and must be extended. 1. Be sure to switch green/white and yellow/white wires on TPS Injectors and injector resistor box Connect the yellow/black wires from the two DX injector harnesses and run it to the yellow/black wire on the injector resistor box. 1. Connect the yellow wire from the DX injector to the #1 injector (brown wire). 2. Connect the red wire from the DX injector and run it to the #3 injector (blue wire). 3. Connect the A3 wire to the #2 injector (red wire). 4. Connect the A7 wire to the #4 injector (yellow wire). 5. Connect the 4 red/black wires from injector resistor box to each injector. Cylinder position sensor Connect C1 to blue/green wire on cylinder position sensor plug. 1. Connect C2 to blue/yellow wire on cylinder position sensor plug. 2. These wires are off the Si distributor so connect them there. That's it. Double check everything and start it up. Good luck! Link to comment Share on other sites More sharing options...

90Tegtyper Posted November 19, 2006 Share Posted November 19, 2006 you have an auto? you cannot use the pm5 ecu for mpfi swap gotta use a si(pm6) Link to comment Share on other sites More sharing options...

cloc007 Posted November 19, 2006 Author Share Posted November 19, 2006 you cannot use the pm5 ecu for mpfi swap gotta use a si(pm6) thats what i assumed i was also told i could use the 88 -89 teg ecu i know that works but first do u know where the ecu is in that year integ its not in the passenger floor or kick panel and do i have to use an si ditrib Link to comment Share on other sites More sharing options...

cranny Posted November 20, 2006 Share Posted November 20, 2006 my bad , i did think you could wire a PM5 for mpfi. he could use the teg ecu , but its not the right fuel map for the engine. would run rich , idle crapty a bit prolly. sorry dude , my mistake. your best bet is getting that pm6 from teg and adding those couple extra wires to the existing harness.

cloc007 Posted November 20, 2006 Author Share Posted November 20, 2006 dizzy is the distributor and yea me and a friend have done it before thanks alot man so every thing works good on the one u tried?, well hopefully ill get the "dizzy" and ecu tonight u've been a big help Link to comment Share on other sites More sharing options...
90Tegtyper Posted November 20, 2006 Share Posted November 20, 2006 thanks alot man so every thing works good on the one u tried?, well hopefully ill get the "dizzy" and ecu tonight u've been a big help no problem, I have the ecu sittin here ive been tryin to get rid of it. and yea it worked but we had to go over th wires a bunch of time lol and when you count the pin in the harness at the ecu make sure you do it like it shows on that site Link to comment Share on other sites More sharing options...
