Neil 1 would like to think that most all normal data made available via OBD2 would be available from this GoWesty EFI Management System,, But, the info that is viewable via the ScanGauge that GW provides with the kit doesn't seam to be all the same info that is available via an OTC ScanGauge like the 1 I have on My VDubaru, which makes it appear as though GW has some how loaded the provided SG with a Proprietary Program that may only be capable of providing a limited amount of data &/Or the ECU that GW uses in this Kit may only provide info that GW deems important ~ The GW EFI that I have installed belongs to a Friend Who lives 60Mi's away so I don't have the sort of access to it that would allow Me to do a lot of on going testing along those lines ~ ORR ~ DeanB
