[Geze-]

Hi I’m new to this forum, I’m learning how to tune but idk how to convert my N/A 4G94 engine to speed density is a 2002 Lancer OZ Rally and the ecu is a MR plastic one can someone explain or help me please

Have you got a speed density ROM that suits your ECU?

If not you’ll need to make one from scratch which is beyond the scope of most people. Have a good search, you may need to buy one from someone like Tephra and get going with that.

Right now I have one but Is very unstable and idk how to do one my self I’m trying to see if someone else can help me or give me tips for it

Unstable? You mean it runs but runs badly? Or is the software unstable?

Runs rich on starts and then gets the map that I made but is after a 30m after the car is running and is like when the car gets at 180F

Idk what’s happening with that map and has the thephra mods and some things like that but idk how to get it to work correctly.
