S-080 Lambda switch question

Post by firemanjim »

Working on a turboed 2004 Hayabusa here with a DTA S-80 running it. Had to do a bit of rewiring as the previous owner had butchered the harness a bit. Has a wire to the Lambda switch pin, but I have no idea what it does?? Any help appreciated.

Look at the map that is on the ecu, and refer to manual for options

Lambda switch is also Map 2 switch, so it will be one of those two functions

I have the map downloaded to my computer and have read the manual, do not quite understand it still.

I think you need to answer the following.
Does it have a lambda?
If so look in the lambda parameters page an see if the lambda switch is enabled, if so the input turns closed loop on and off.
If this is not checked go to the als/map 2 page and check if this is turned on. Typically this feature is used for anti lag / different boost strategy depending on what additional hardware you have.
