Nitrous install is going down Tuesday. any tips? advice? anything anyone knows that might pose a problem and knowing a little extra might help? anything is appreciated. thanks.

 

Had CRH install mine.
Advice mmmmm make sure your ignition system is solid, ie my plug, coils.
Use the highest octane fuel you can buy, I find 94 octane I find is better than 91. (I've heard ugly noises with 91)
Premix, assuming you're doing a wet nitrous install you will want add a bit of oil to that extra fuel (IMO)
DO NOT engage the nitrous lower than 4200 rpm.
I would strongly recommend not using a nitrous shot over 65hp unless you have some serious tuning. (55hp shot to start)
Again if you are using a wet system check your fuel line connections. I had minor leaks after a few drive cycles.

Juice and Juice often!
OH and if you juice in first gear, be ready to shift quickly. That reminds me, turn off the DSC you don't want traction control breaking in cutting fuel to the engine while you have the juice on.

 

Which kit are you using? I hope it's the ZEX. And as mentioned before, start with a small shot.
Do you have an Accessport?
Read the instructions. Make sure you get the wiring correct. I heard of a fellow that didn't and popped a manifold on start up. Make sure your fuel connection is not leaking. Turn the key on with out starting it when everything is hooked up and check for fuel leaks. Same with the Nitrous tank. Turn the bottle on and check the connections.

 

well to clarify yes it's a zex blackout kit purchased from CRH. And no i dont have the accessport...yet. and im only going to be running a 55 shot. have a new fuel line to throw on. and i know all the preventative measures. and i always use the highest octane i can find. and yea all my coils, plugs, and wires are new, less than 3000 miles on them. i was more talking about the physical install. any tips that would help on getting the system in?

 

oh and also, no dsc...so no need to turn it off.

 

The fuel lines a bitch to get to just take off the UIM and it will go smooth, I didn't take mine off to install it but it took me forever. Do you have the BHR TB spacer or stealth nozzle?

 

i hate the spacer. but no stealth nozzle.

 

Might I inquire as to where your going to place the nozzle?

 

what do you mean? in the BHR spacer.

 

wow im a dumb ***. i meat i HAVE the spacer. not HATE. i love the thing. lol.

 

HAHA that's the way I read it as well.
"he hates the spacer and no nozzle... hmmm...."


good luck on the install. You may already know this, buy my only advice is not to use teflon tape. Tiny pieces can come off and jam the solenoid.

 

lol yeah. i guess ive just had a bad night and thats what was on my brain. lol. all right what would you use?

 

Red Loctite for the nitrous connections to the solenoid. I'm sure plenty of people know that, but I didn't know when I was first learning about it. Obviously, dont use it for the connection to the bottle.

 

Well now that that's cleared up.

 

So I've never looked into the DSC, but please tell me that Mazda wasn't dumb enough to just cut fuel to the engine in order to get traction back. I can't imagine this playing well with any FI setups at all, let alone nitrous...

 

I dont think it cuts fuel, but engages the brakes. I cant remember the difference between TSC and DSC now...

 

I have no proof but I would be willing to bet it does shut the fuel down or at the very least take control over the fuel

 

We have drive by wire right? Wouldn't it make more sense to just pretend the throttle position was set to a different value that happens to be calculated to bring the car back under control? I don't see why any auto manufacturer would purposely force the engine into a lean state to help slow it down... unless the goal was to slow it down permanently by blowing the engine?

 

Agreed,
I did say fuel but I was loosely referring to throttle position, either way if you're under spray you don't want either to change from WOT.

I guess what I'm worried about is having the my foot all the way in to it (my nitrous is activated by WOT voltage situation) and then having the DSC or TSC kick in while I'm trying to spray a 65 shot down the throat.

Perhaps (and I don't know) the nitrous would be shut down during a DCS or TSC situation from a drop in throttle voltage?
Now that would lead to an interesting situation where you could get quick repetitive burst of nitrous while the car is trying to gain control.

I worry less about this than I do hitting the RPM limiter in First gear under juice. How do you suppose Mazda handles the RPM limit? <shrug>

 

ugh. well the install was bumped to friday due to everyones work schedule. it's eating at me. im so tempted to just go at it myself, but i dont have the time, and it'd be much easier with another person. oh well. cant wait.

 

^^^ check 4200 understood.

 

I hit revv limit twice when sprayin and nothing happened besides a big boom and flames out the exhaust which happens when I hit revv limit without spraying so everythings good.
