100 octane, 1 or 2 step colder plugs, and taking 2-4 degrees out of the tune will be safe to run a 150 shot. Rule of thumb with nitrous is don't go over 50% of the motors original hp figures. Run wet kit with a tune and a little on the richer side. You can do an NA tune with a wet kit and run .02 larger pill than "calculated" on the fuel side to be safe also.

But I have also heard horror stories with the ZEX brain. It's an awesome system IF yours works flawlessly. I had a friend who had a bad box straight from the start. Another that failed halfway into the tuning session and his 3rd box failed 3 months after that. Originally my kit I had built for my Z was a full dyno tune fogger kit with all the bells and whistles available.

I've really thought about switching out the box but I am unsure what kit I could go with and what would have to be rewired. I am guessing I can just the solenoids and it would be fine wouldn't?

Finally
 

Just got the dyno sheet from Z1. At this time they do not want to continue use with the nano system as they feel it is the reason of a complete failure last time.

Impressive numbers!!! 100shot right?

Why do they feel it was a nano issue??

THank you yes 100 shot

They are saying that they feel the previous failure was too much cylinder pressure

I was at 440 with my NX kit... With old exhaust very restrictive. Probably would have hit 450 rwhp with the motordyne I have.

NOS noob here.. What is the purpose of going SPPP SPHHH before you run? It is priming some line with the gas or something? It looks cool every time i see it.

He is purging all the air out of the line so that nitrous instantly hits.

Removing gaseous nitrous from the lines so fresh, liquid nitrous is ready to be injected through the solenoids.

Ahh.. I just see it on cars prior to a pull. It looks cool and I never knew what the heck it was or for.

Just an update. No bueno on the tune. I'd rather not get into a bashing session so I'll just post the maps up here in a little bit.

So ya those are the maps. One is the N/a tune and the other is the Nitrous tune. Does this look right to anybody?

What kit are you currently running?

Wow; just read through all comments,,,must have taken an hour.....sounds like a really bad experience with the gas.
it crossed my mind at one time to get an edge & only use it in 4th-5th gear(7sp auto)
nut after reading through all of this-it's scared the sheet out of me.
y'all have a nice day.

... Just ordered my NX kit. I'm on ECUTEK so we'll see how it treats me at the end of the month.

sorry for diggin old post but I have to ask hows everyone's nos going on?
im really interest in installing a 75/100shot kit as am still saving for a TT set while I cant wait to fly, safely .

Has there been any further progress on this build? I just purchased this exact ZEX system and its getting installed next week. Im worried now after reading this that iv got a lot to think about

I've heard it's best to have it dynotuned in...no first hand experience with it; but tuning it in will make it more "idiot-proof"
