Is G4X closed loop lambda suitable for WOT?


Recommended Posts

Is CLL in "Auto Mode (Wideband)" suitable for full load operation? There are lockout settings that are set up to lock it out at full load but do I have to lock it out? Many factory and aftermarket ECUs work well with closed loop wideband under all load conditions including WOT.

No problem, just set tps lockout to max (110%) and Map lockout to something like 500kpa. 

I recommend to use link can lambda or internal on Furry and Thunder ECU, because they can dectwct wrong sensor which sets CL lambda to openloop. 

On analog lambda it could be possible that a wrong sensor leans mixture out.

On the G4X if the Lambda value is above 9 or below 0.1 CLL will not run.

Also a map or tps delta value of 0 means no map or tps delta lockout.

Max tps lockout value is 0 but the tps value has to be greater than this value to hit the lockout and tps cannot be greater than 100%.
