Again, the EGRTemp on a 1G and the Baro input on a 2G are problematic for some aftermarket sensors. When feeding certain wideband kits into the EGRTemp input on a 1G, for example, you may see normal A/F ratio readings above 11.5:1 but then the readings flatline there and won't show any value below that. | Again, the EGRTemp on a 1G and the Baro input on a 2G are problematic for some aftermarket sensors.
