Safc maps KA? - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

Just curious but does anyone thought about setting up a thread to share Safc settings based on Injectors and PSI? You know kind like: Mine was tuned at 14.5A/F running 480's and 14psi set at -32 low and yahta yahta. (just an example)

Now it would certainly be a use at your own risk thread but would give most a good idea of a safe base setting providing boost, injectors and such matched. Just a thought unless there is one somewhere that I have allready missed.

Sry if this is in the wrong section wasnt sure where since it is kinda a tech question.

I could use some good 370cc, 8psi Safc II maps

every car is different, get your car on a wideband and tune from there.

OK so all factory ecus are tuned differently on the car. NO I am saying that anothers maps can be altered slightly to run safely on similiar setups. I didnt say optimally but safely. I have no dyno close and do have access to a wideband but it is not immediate access. Sharing maps so they can be a starting point should create no problems if you do it with common sense. Thx though but I think you kinda missed my whole point of the post.

To clarify I have searched and searched for the safe settings to run 370's at for initial fire up. I finally had to ask then it got strung beetween N/A settings and Turbo settings if there was a thread listing what peeps setups are and there maps it would be easy to figure a base setting to fire off of.

The only base maps to rely upon are basic math...

If the stock injectors are 270cc, and you're running 370s...then it's -27% across the board (270/370 = .73 ... (.73 - 1) = -.27)

Stock is 270 and you're running 480s...then it's -44% across the board (1 - (270/480) = -.4375

Etc, etc...
