Does the TRD down load hold the map/download when the battery is disconnected? I know on my motorcycles the power commander keeps the map just curious if the toyota ECU holds the download when the battery is disconnected or goes back to stock programing? Thanks

I don't understand what you are asking.

O

No the ECU reflash does not reset itself when you disconnect the battery. Also, there is nothing downloaded onto the ECU as far as i know, just a re-flash.

May I ask what a "RE-FLASH is? I assumed it changed the Air fuel ratios at different RPM's maybe in each 250 cells of RPM. My background is power commanders on motorcycles so I apologize for not understanding what a RE-FLASH does. Thank you

This is a picture of a map on my motorcycle you will notice + & - numbers in separate cells at 250 RPM ranges. My question was answered thank you but I felt my original description of my question was misinterpreted
Thank you
