Hi,
actually my wideband is not working so i'm relying only on narrowbands mV.
When i tuned the car with wideband for 12.5AFR at wot i was at 860-865mV narrowbands average value at IAT 50°F (tested on February-March).
With IAT 70°F i was at 850mV (tested on May), now today with IAT 90°F i'm at 840mV so my understanding is that i'm lean a little with the increase of IAT..
What table can i use to compensate the fuel vs IAT?
I'm thinking the table with injector flowrate vs IAT to put something like 0.990 at 86°F and above to increase 1% fueling (it should state the flowrate is smaller than 1% so it will increase by 1% everything) but i though there should be a table for airflow vs IAT under airflow....i've seen there is cylinder charge temperate and some table with IVT like openloop gain but not sure...
Any suggestion?
Thanks.
