Ok i finally got around to wiring my nitrous to my S300 and so far it hasn't worked. This is how i wired it up....



and this is from hondata's web site, and from this I see that 85 and 86 are switched from how i wired mine... Would this be the problem? Or should it still work?

 

So after some thinking i came up with this wiring setup sketch....

Is this how it's suppose to be?

 

The output from the ecu/hondata is a ground which means that the way you wired it, there is a ground to both 85 and 86. Go with Hondata's wiring.

 

Does the wiring in my second post make sense? Or should I still switch 85 and 86 around? Or does it even matter? Cause from hondata it says that 85 should be the output control and 86 goes to a switch, so does it matter that 86 is wired to the output control as long as I wire 85 to a switch?

Why do you have a ground on the other side of the switch? You're going to short as soon as you flip the switch like that. Take out the ground and you'd be ok, but you'd have one more switch then you need.

The way you have it wired now you are grounding a ground. Your relay never works lol.

Wire it like Hondata has it.

 

on hondata's wiring diagram it said 12v switched? What does that mean? do i put that to a manual toggle switch or to 12v power source

 

i think your making this too damn hard dude, if the hondata ecu sends out a ground u need 12v, if it sends out 12v u need a ground on the other side. simple basic circuits

 

switched usually refers to 12v switched, which means its on when the key is in the On pos.

 

Ok cool, I finally got it to work. One other question though, when i'm in hondata setting up the parameters it gives the option of inverting the output pin (A20) I tried both ways and the nitrous solenoid still comes on. So does it matter what it's at?

 

your killing yourself with this

if it works just leve it alone and get it tuned

 

i'm not using it until i get it tuned, but I just wanna make sure it's in working order before i take it to get tuned so I don't look like an idiot.
