The OR H is not an issue, all it does is set a code, does not change how the car runs.

Pull four or five degrees to begin with for 100 shot. With good gas (100 octane plus) advance the timing a degree at a time. Most people are ok with STOCK ignition timing for a 100 shot (not a 93 octane N/A tune). Hope the clears it up. Be sure to install copper plugs!!!!

 

^ this, most people just resort back to stock timing when running spray.

not only install copper plugs, but install plugs that are 1 step colder.

Heres a little read for you

Do you have a Zex system?

 

I did look at the nitrous sticky but it didnt answer my questions.

Once again i looked in there but my question is should i just retard the timing off of the 93 OCT tune with my diablo and run -1 plugs


And yes i do have the ZEX system

 

All your 93 tune does is up the timing. so start out running stock timing and go from there. If you go on the zex website they tell you how your timing should be

 

^^^ That is a good write up. I was doing all that stuff back in 2004, I even had a latching relay setup off my dynojet WBC relay output for A/F switch. Lord all the safety stuff is expensive and a ton of wiring. BUT I ran several hundred pounds of nitrous. I was buying the mid 60# big bottles with siphon tube and filling my own 10# bottle!!!

 

Like I was trying to say subtract 4-5 degrees of timing with the 93 octane tune. Or install stock tune and leave timing stock. That is for 100 shot, and yes 1-2 step cooler plugs is needed.

 

Just return it back to stock when you wanna spray it, thats what i used to do.

 

thats all i wanted to know. Thanks a lot fellas

 

Well on the install paper that comes with the zex kit says that you should advance the timing by 2

 

That doesnt make any sense, i would call and just ask them about it ive always heard - 4 to 5 degress for 100 shot and i pulled 7 degrees and 2 step colder plugs for my 150 shot.

 

My bad i ment retard

See scroll down to number 10 on there instructions about the timing

Thought you was talking about a 4.6 2V, they are pretty retarted from the factory lol (the timing that is)

 

I read somewhere that it's just as good to run Iridium plugs???

Is that right?

 

NGK TR-6 plugs is what you want

 

I did read your write up, was very nice... I did get 1 degree colder also

I just got the NGK Iridium's whatever those ones are
