                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
