Stock narrow band voltage outputs

[stigmundfreud]

Does anyone have them?

My understanding is at lamda 1.0 the stock no2 should be around 0.45mv is this correct? I need to know what voltage it should be at 14.7 or 14.64 afr

the car in question is a 5.7 ls1 2004 Monaro/GTO

thanks :D

Typically, the reference voltage used to indicate an AFR of 14.7:1 is 451 millivolts. However, the actual voltage used as a rich/lean switchpoint varies. Take a look at the values in B4105 in different tun files to see for yourself.

thanks, the default as you said looks to be close to 440 for idle the lc had been set to 0.4 - adjusted the outputs from default to how it was shipped and it now reads right for 1.0 lamda
