Digital gauge or obd port monitor (HKS OB link or DEFI smart adaptor)
I came across those product. HKS ob link and Defi smart adaptor. Is there anyone who has those in their car ? Both use bluetooth to display readings from ecu to your cell phone or android iPhone devices. To me, it beats having fixed gauges inside the car. Is it possible to have reviews on those product ? I have looked into them but with limited information.
thanks
