A wet system you will need to spray after the maf so it doesnt add any more fuel.( It will read the gas etc as extra airmass & add fuel to suit.) Also if you spray before the IAT you could possibly damage it.
There was a method where the IAT sensor circuit was opened with a relay when spraying. This would make the IAT sensor read -39degC & you could pull timing in this area with the spark IAT table. I have never tried this method but basically understand the principle.
I personally use the COS5 custom operating system that utilises a pin in the pcm to modify your spark & fuelling tables. I do not know if this is a possability with your OS. Check the custom operating system section.
nothin in the custom OS box idk man im just lost im a diesel man this is my best friends truck im workin for free so i have no idea. should i go mafless tho?? i just dont know what to do i can in stall the n2o system no problem but programming for it im lost i know a lot of gassers dont like to help people a whole lot b/c its conplicated but im trying to learn and really need help man if i send u the tune i got do u think u could set it up for the nitous??? or who that be inpossible??? thanks a million man
I will help where I can. I am not familiar with the operating system in the truck so the first thing you should do is post the tune file. From there maf or mafless wont really matter apart from deciding your nozzle positioning.
One thing to note is the truck should be tuned properly NA before you look at tuning for nitrous. This will make the transition for the gas much easier.(and safer)
n20 for begger thanks help
