i wanted to put on a switch for the piggy back so i can turn it on and off. i think i'm gonna run n2o but i can't have the piggy on with it. which wires do i run to the switch.

 

the power wire?

 

but then your car will have to re learn every time you switch it off and then back on. if i were you id go one way or the other n2o or na

 

No! If you just cut the power to the Piggy, you're cutting off the airflow signal to the ECU, too. You'd have to wire it so the airflow signal was switched from the sensor to the Piggy or to the ECU. You could leave the power running to the Piggy, it doesn't draw much.

The ECU would probably need a reset every time you switched, though. It adjusts itself to the signal it gets from the Piggy, and should be allowed to adjust without it when you switch it.

EDIT: I'm with mitsutech, either go Piggy or go N2O, IMO. Not both. Too much resetting and relearning for the ECU.

 

thanx for your help. i guess i'm stayin na for the time being.

 

technically n20 is na

 

actually its not n/a cause its come sort of forced induction!!!!

 

I could be wrong here but my understanding of it is that is is n/a because its not actually changing the atmospheric pressure in the i/m, hence no f/i.

 

The N in N/A is for naturally. If there were naturally occurring clouds of N2O hovering just above the roads that you could drive through and get a boost (like in some old video games ), then N2O could be considered N/A.

It may not qualify as F/I, but it certainly is not N/A.

 

i call it FI cause you are shooting nos into your motor which gives your crap load of power, like turbo, shoots air into the motor to give the same thing. when which i call n/a just going off of what you have running the car

 

Thanks for the clarification, I did however know what the N meant, I see it more as an additive, like race gas or such. Air is still forced into the cylinders at natural atmospheric pressure isnt it? Don't mean to start an arguement, just really asking. I know of only the two classifications of N/A or F/I in the context of this conversation, so I picked N/A. Hope this doesn't turn into pages of us all saying basically the same thing, because I pretty much agree with you, I think.

 

Why would you want to turn off the piggyback when you run n2o??? I think that piggy back would work better with the n2o because what the piggy is doing is putting more fuel therefore increasing the power. when you run n2o, you will be injecting more air in, so when you are put more air in, don't you need more fuel to make more power? The ecu is also programable, so can't you tune it so you can run more efficient? Am I right??? Please correct me if my theory is wrong.

 

 

mitsutech told me not to, on less i could get it tuned. i think it does something to my timing and all that. i believe him, cause he aint no slouch when it comes to nitrous.

 

the piggy leans out the fuel in the default map, hence the suggestion to get it tuned for n2o
