Whats Involved In Tuning?

[VB-]

not specifically for a skyline but any car in general, what is involved in the process of 'tuning'.

from what i've seen/heard/read, the main things with tuning are getting the A:F ratio's right throughout the rev-range, and feeding in as much ignition timing as possible, till power drops off/detonation sets in and while avoiding detonation the whole way through the other stuff aswell. but what else is there? i know some ECU's need to set up idle control etc, but what makes power?

and if anyone here is a tuner/does tuning, where did you learn, what was it on, how long you been doing, what have you tuned etc, all the good sh*t :laughing-smiley-014: dyno vs road tuning?

cheers,

dyno is always better becuase you can go the full way to redline without having to worry about traffic and slowing down.

as for tuning you want to keep the AFR's at about 12.0:1 on a turbo car (leaner on a NA). and you want as much timing as possible before it pings. to start out with you basically just do trial and error, basing it off the initial map to get where you want. if you are just learning you make small changes till you learn how much of an effect the changes have, then you can make educated guesses. but you still need to know the principles of everything though.

yeah the other thing i forgot to ask was equipment, the only things i can see that you would need are a wideband and an accurate knock sensor? thats apart from ECU plus laptop/controller of course
