Hello!
I have Vems 3.3 with Bosch wideband ego.
Engine turbocharged.
What I must make to obtain to a relation lambda of 0.83?
Where I can obtain instructions from how to do setup? :-\
You need to set the lambda table to 0.83 in the areas that you want it to occur, then with that as a target you need to adjust your VE table to suit.
Can you datalog what is happening now and provide the MSQ from MegaTune and I can talk you through the fuel tuning.
Cheers
Rob
