I bougth an apexi afc neo for my for my 06 lancer es...Im wondering if anyone knows how to tune it...and how to???

 

Man, those things are all foreign to me. Did it come with an instruction manual? If not, I know you can find the manuals for them on Apexis website.

 

It did but it it was a lil bit confusing...u kno wut I mean

 

Do you have the basic knowledge about tuning, and what changes what, etc?

If not then you really can't answer your question until you take some personal time to read up on all of that stuff

Get a wideband.

 

Just remember an afc is an "air flow controller" what this means is when your adjusting your "fuel" what your really doing is modifying the air flow signal to the ecu,by doing this if the ecu thinks your getting less air then its going to give less fuel and more flow more fuel. This also will inadvertently change your timing too

 

I tuned my 97 eclipse gsx with a safc2 . I was originally tuning with a pocket logger and watching the front o2 sensor voltage, keeping it at .96-.97 ... Then I finally got around to getting a wideband and man was my tune off , I highly recommend wideband, you cannot tune with your safc without somesort of device to monitor while you tune example evoscan , wideband gauge , pocket logger , ect.
