Both chinese knock offs 1 works but is lazy, to me it seems thst the switch between 4,6&8 cylinders isnt working gives idle and cruising rpms fine but on a fast revving engine its too slow to represent actual rpm. 20 quid buys it.
2 nd one is faulty, if you know electrics you could possibly fix it, cuts the engine out when connected to the negative side of the coil ten quid. both have programmable shift lights .
