Hey sorry for the lame questions but I have been searching for the past day and still can't find any info.

Im using my friends s300. I need to datalog my AFRs cause I need to tune my car as best as I can before my Hillclimb race next weekend.

Currently running 1.6 sohc Jrsc with I highly modded s-tube and custom Laminova cored Air to water kit. It works great only logging 160F max IAT's which im really happy about. What kind of afr's should I be going for 11.8- 12.2?? Also I dont really understand the vtec engagment files do I just set the to settings to the same RPM.

Im trying to keep it simple but I want to clean up my tune. Also one more stupid question Do I need to run in closed loop to tune I still run the stock o2 sensor and then my AEM.

I have pined my AEM widband to the d10 ecu pin out. I have set in the closed loop tables the follwing.

Target Voltage 0.51
wide band input D10


Target Voltage 0.51

Voltage offset 0

Conversion table


Voltage Air Fuel

0.00 10.01

5.00 20.00


Settings box ( units is checked)

AFR

Do I do anything to the Anolog Tables?

I am seeing logs of Lambda but in the graph at the very left side I see

0.7 on the bottom and 1.4 on the top.
AFR.

Feel free to look at my setup and suggest anything that I should do to my tune. Its preety much a stock download. We have 94 octane here in Canada. Could I adjust my timing at all. I may be going to a dyno this weekend to see what its putting down for power and may have a tuner on hand so any suggestions would be great.

Thanks Shane

Double click on AF in the sensor list and change it from Lambda to AF and then set the min and max to 10 and 20.
