General What and how to fit a rev-counter?

[nuvolarossa]

Hi, I need a rev counter for my panda. I've searched on cinquecento forum too (because use the same 899cc engine of mine), but I'm a bit confused. I should use a rev meter for a 2cyl or 4 cyl engine? How I can fit it? Where is the negative of coils? Pics?

thank you
Mine is a 900ie (899cc 4 cyls with ECU and one injector).

What is better? Buy a 2 cyl rev counter (because my panda has 2 coils) or try this solution with a 600 sporting rev counter?:

If it works in a cinq 899 should be fine in my panda too...!!

How much is the rev limiter on my 899cc engine?
Where I can find the diagrams for ecu pins?

thank you

i fitted a rev counter to my panda 4x4, theyre simple to wire in really. If you get a "TIM" gauge they tell you where the wires go and they have a switch to change for engine types. In fact all guages should have a manual with them. If not PM me and i'll scan and send you the instrucions mine came with! Hope that helps.

Just a thought. The later Panda instrument pod looks similar (ish) to a mk1 Uno. I wonder if a mk1 Uno SX or turbo instrument pod could be adapted to fit in place of the original If it does you'd only need one wire to make the tacho work

depending on the size of wheel that the uno had fitted and the revolutions on the gearbox wont the speedo be out???

but at least the tacho would work

A lot of Pandas used exactly the same steel wheels as the Uno (13"). Not sure about the final drive ratio, but as the Unos came with different final drives depending on the models yet all used the same speedo maybe the speedo drive takes its info from the output shaft or something
