Correct Air/Fuel ratio for 2008 tacoma?

Does anyone know what the correct ratio for air to fuel in a 2008 tacoma 4.0l, i want to know for my scangauge II when i get it. i don't want my truck to be running to lean.

 

you cant read afr with the scangauge

 

some one said you could. do you have one?

 

yup I have one, you will need a wideband to measure afr. you can get one from URD or many other places

 

what about the new Xgauge upgrade, i thought our ecu could read this with the right codes?

 

you might be able to with other makes but as far as I know it is not possible for the tacoma. Just from reading your mod list I would not worry too much about running too lean, although it is always nice to know where you are at.

 

yeah it is just for peace of mind until i get it supercharged.

 

You shouldn't have any reason to worry about your AFR, and the scangauge wont be able to read it.

 

Hey guys with MAF calibr - Which intakes affect this the most...

 

URD most likely because of its true cold air intake qualities. i didn't get one because i didn't want to snake the tubing through to the front and its not legal in California anyway so it takes longer with the setup to revert back to stock when i need to.
