quick inline resistor install ?
 

Hey everyone i just bought some 10 watt 10 ohm inline resitors and im installing them on my obd1 civic for my 450's. I just run them inline on the yellow wire with the black stripe coming off of the injector right and leave the other wire alone. Is this correct? I think so but just want to make sure! Also do I need to grind down the little bump in the inside of my 450 to make it fit in my obd1 clips?

anyone???

yeah i wanna know too..haha. seriously though i know u can run the resitor pack, but since i already have the 10w 10ohm resistors, i also wanna run them inline. could i just use the stock dsm clips? or i gotta use the obd 1 clips that are in my civic now? and pics or diagram would be helpful..thanks

yah i know you can just grind that little notch down inside the injector and then they will fit into obd1 car clips ill get a pic of it later but I still need to know if I should put the resistors inline on the yellow wire with the black stripe and then leave the other one alone. Cmon all these people runs 450's and no one knows the answer? ;D

yeah bump this...

Re:quick inline resistor install ?
 

you got the right idea buddy...start cutting wires

Re:quick inline resistor install ?
 

dsm clips or my stock obd1 clips?

Re:quick inline resistor install ?
 

either shave off the little ridge inside the injector or use the dsm clips

thanks man! that was a lifesaver.

ok.. this has been a confusing topic for myself for sometime now.

4g (88-91) civics/crx's use peak & hold. the ecu is expecting to see the same resistance as stock injectors so you retain the injector box.

but 5g and newer use saturated injectors. with no resistor box from the factory. why do we need to add a resistor to the dsm injectors if the stock ones don't?

Re:quick inline resistor install ?
 

because the dsm ones arent the same as stock...the ecu will freak because of the difference in impedence

Re:quick inline resistor install ?
 

uhm...

still confused.. can you "stupify" that explaination.

Re:quick inline resistor install ?
 

Lemme try: Because DSM's use LOW impedence peak & holds, your 92+ Civic uses HIGH impedence saturated injectors. Hence we must put resistors in line to make the 'electrical pulse' if you will... compatible. otherwise, prepair to grab your ankles!

thats about as layman [sp] as I can get.

Re:quick inline resistor install ?
 

Right on gimpy...

bottomline is that the ohms needs to match up or at least be in the same range of resistance.

honda stock injectors for 5g is around 12-16 ohms (dont remember exactly but its high impedence)

stock DSM injectors are around 4 ohms (low impedence)... thats why you have to add the inline 10 watt 10ohm resistor.

4 ohms + 10ohms => 14 ohms right around the resistance where the ecu is looking for...

=P~ Looks like I learned something WUHOO!

and let me guess. stock 4g injectors are 4ohms aswell and the resistor box bumps it to 14 ?
