How is installing an electronic boost gauge different from installing a mechanical one? Does anyone have instructions on how to do this?
You'll be tapping for a boost line as you would with a mechanical, but will only need to run the line a short distance to a control-unit which will often reside in the engine bay. From the control-unit a wiring harness will need to be run through the firewall to the head unit.
Greddys are this way, which each head having it's own controller. With Defis on the other hand you daisy-chain the gauges together and I believe they are driven from a single controller.
Not having to run a boost line through the firewall saves a major headache IMO. Electronic gauges, apart from being more accurate have an added coolness factor: When you turn the key, all the gauges come up to the 'home' point.
