would someone mind better explaining how the w/i???

 

Water Injection works in two ways.

1. It cools the incoming air charge down even further than the intercooler does. (Below ambient temps even).
2. It slows the flame front, reducing the tendency for pre-ignition, basically the same thing as running higher octane fuel.

WI works really well in our cars because the ECU sees the lower temps intake air temps and compensates with more timing. Which, because of the "octane effects" of the WI, doesn't cause knock so you get max ignition timing safely.

 

Another question. If I get the Toys box from N2MB, do I still need to make sure and get the Stage 2 w/ Toys ECU or will any Stage 2 ECU work?

 

And yet another question...I have an '05. Do I have to get an ECM that was made for an '05 or will any ECM work?

 

i think any s2 ecm will work....and a 05 if im not mistaken should be the same as 03-04....i think its just specific to your mileage....when u call in to order they'll clear all that up 4 u.....if they dont...then stay away, or at least thats my understanding

 

There was a change to the ECU from 04 to 05, I believe in 05 they got rid of the battery temp sensor. It's something you want to double check for sure.

 

there u go...take mchat's word over mine! (look at my car and look at his, he knows a lot more about these things than i do!)

 

Well, I bought a Stage 2 with Toys ECU today and I'm planning on ordering the Toys box from N2MB tomorrow. Now I just need to find a good deal on some injectors and sensors and I'll be set. I think I'm going to get a W/I kit also. I've been reading about them today, and it seems like what I need.

 

Wow, been a while since i've been active on these boards! Sorry I didn't get to see any of this until today. Thanks PSI Chick for passing the word around

If you run into any problems, feel free to email me at hozay@n2mbracing.com or PM as you have already done so on the other forums. As you can see, i'm not very active on here.

 

I would get a Stage 2 WITHOUT toys cuz really you wont use the toys that much.. get the stage 2 and then get other mods like exhaust, motor mounts, intercooler!!!!!!
