Caerbonet electronic tach
ian.stewart - 14/10/23 at 09:02 AM

Just removing my Webers from Vauxhall C20xe, they have a MBE mapped ignition kit fitted, no Issues with them at all, except for the usual smell of fuel, I have acquired a QED/Jenvey direct to head injection system which is my winter project, it has an OLD DTA pro400 ecu already set up for a vauxhall so it would be rude not to use it
How do I wire my Caerbonet tach and can I get new pins and plugs for the tach?

I have a Smiths (caerbont) electronic tach. It wouldn't work properly off the ECU tach out signal, no clue why, but it works fine with the signal wire fed from one of the coil pack LT wires. Just need to set the appropriate number of cylinders so the pulse count gives the right RPM. From memory the tach has two signal wires, one for ECU signal and one for coil signal so use the right one!

Thanks for that, I used to have that info on my computer, I dont think there will be an issue with setting up the Tach, as it has already been running on basically the same setup,
