I'm running the 75 shot jets with the Zex kit.
No issues yet.

MM Custom Tune, BHR Throttle Body Spacer, BHR Coils, RP High flow cat, RB Cat back.

^very jealous. did mm tune for nitrous?

Yes he did.
At that moment in time it was the 65 shot sooooo I'm over stepping his tune (bad me).

I don't know exactly all the magic accept that he retarded the timing a few degrees and the map is richer than a typical ideal fuel map for an NA tune.

Still I'm always careful, listening intently and only engaging the spray over 4.5k rpm not mention a strict fuel diet of Sunoco 94 Octane

What sounds are you exactly listening for? Detention right? And what does it sound like? I just starting running the 65shot with no tunning and I don't hear anything out of the odernary that's why I ask.

Ya detention or pinging.
How does it sound? mmmmmm I guess I would explain it like someone leaving a 1/2 socket or wrench in your engine.

I've not encountered that issue yet. (KNOCK ON WOOD!)

Easy_E1 could likely explain why he has had it happen but for myself I'm chalking it up to only engaging the nitrous over 4.5k rpm and allowing for a little bit of over run after shutting the nitrous down.

ie) I don't flog the **** out of it up to 9k rpm and instantly take my foot off the peddle. I try to depending on the situation to either keep the revs up in neutral or let the rpms come back down slowly in gear while still apply some fuel.

Easy_E1 spoke to me about this method or at least that's what I got out of our conversation anyways.

Easy_E! you're not still blowing manifolds are you?

I've read that a tuned map on the AP should b applied b4 a nitrous install what are your thoughts on this guys and what would MM tune for a nitrous setup!

Flashwing

A wet shot nitrous system due NOT require tuning of any kind. As long as the car has a properly running tune then the nitrous system will work fine.

As long as you use correct jetting sizes there's no reason to apply a tune at any point with a nitrous system. If you "tune" for a nitrous shot you'll spend 99.9% of your driving time with a substandard tune for that .1% of the time you're using your nitrous. Have the car tuned properly for your non-spray driving and use the jetting sizes to ensure you maintain proper air/fuel.

Ok I think I understand the car will be tuned with the regular mods Ie: intake headers midepipe exhaust, and this tune will have no affect on the zex setup correct? It will just be a finely tuned car with nitrous as an addition?

Correct. Because in a "wet" nitrous application, the jettings will determine the precise extra amount of fuel needed for the amount of nitrous being injected.
All the math and tuning for when you are spraying has already been done for you, just use the correct jettings.

Ok kool! So when u guys talked to easy about tuning for higher jets what do you think was tuned to help the car handle the higher jets!!

And I have a 4port auto like easy_E so I'm really excited to see what will come of this!

toneskii707

And It brings up the question when is BHR going to make? And what shots is flashwing useing?
