How to tune a car, step by step.

[WolfSL]

I was already planning on using stockish sized injectors (450's) and stock ecu to get it initially started just to make sure things were golden. I've already done some tuning with an SAFC and the E-Manage (Blue and Ultimate). So I'm not completely new to tuning, but I certainly wouldn't call myself a pro yet.

I guess what I was really wondering is what kind of things do you take into consideration when coming up with a base tune for a car and/or how you adjust for them (in a new or existing map). I've already been doing a lot of reading up on it, I just wanted another perspective.

Josh, that was an excellent write up. Very well done lad!!!
My hats off to you again. The 3S community new folks are lucky to have that available.

Things I require when making a basemap:
-engine size
-veh year
-ignition specs (COP, DIS, coil, plugs)
-injector size/style
-airflow sensing type
-other sensors
-engine modifications
-gasoline type
-turbocharger choice
-intercooler choice
-other accessories/modifications (like custom fan wiring, fuel pump wiring, etc).
-exhaust/intake work

After that I can usually just make a map that will start the car 99.9% of the time, pending any mechanical problems or other non-predictable VE issues.
