Which ECU are you using with the LS7?

My guages are all liquid filled mechanical Autometer guages as there is no real provision to get any readings from the factory senders connected to the ECU. All the signals for the factory guages are processed by the ECU and then sent as serial data to the BCM. The BCM then relays this data to the guage pod which displays the readings.

It's all done via OBD2 so in theory if you sourced a bunch of Aerotech OBD2 guages you could hook them all up to the OBD2 port and have each one set to display a different parameter. It's something I thought about doing but in the end I liked the simplicity of the mechanical guages.

Cheers
