Hi
I have a stock Vr4 with the only modification being a different ebay exhause manifold and a 2 1/4" exhaust all through. 11Psi boost with a newly fitted ECMlink.
I have tuned my open loop timing maps to remove all my knock. Now i need the better fuel economy for town driving. i will setup to open onto open loop around 35-45% throttle.
What do i need to start adjusting my closed loop maps to get the desired km per tank. Atm on 98 octane i'm scraping 300kms till theres about 3l left in the tank. I looked at the fuel trim demo video on ECMlink but i don't know how to get the CombinedFT to work.
450cc injectors
11psi
2 1/4 exhaust
1g MAF
All sensors stock and working with new Knock and O2 sensor and replaced TPS.
Cheers
