Hi yall,

I have an engine with 3 cilinders (1kfre).now I’m getting bit confused.

Firing order is 1,3,2 and my injectors should are assigned as following: cilinder 1 - injector 1 | cilinder 2 - injector 2 | cilinder 3 - injections 3

Then firing order is

Cilinder 1

Cilinder 3

Cilinder 2

This is correct right?

And I can’t get my map to work (on board the ecu) and Afr reading is showing 14.6 constant (brand new Bosch 4.9)
