Hi Aslam, In theory I wouldn't say it is impossible. But you need to do some homework. Does you santro ECU wiring have a Tacho signal out? If so, is the relation between the number of pulses produced per rpm same as that in Suzuki ECU. Though this would need some internet study or a test with an oscilloscope, I would recommend you to fit an aftermarket stuff if we are not able to decode the relation between the pulses produced by the ECU tacho output signal and the tachometer needle deflection.

IIRC "NO" (except for some special edition which came with tacho in India, whereas the export model or the one in abroad came with factory fitted tacho)

EDIT:
discussed here

Thanks for your swift response ilangop.

As this is my friend's car, need to visit his place to check the ECU wiring and in parallel we are trying to understand more about the concepts.

While scanning, just came across the below post

Now, we are giving a second thought to go for an aftermarket stuff as this looks much hassle free to get it up and running.

I will surely keep the thread updated on whats happening.

Cheers!

Not every aftermarket tacho is compatible with Santro. Look for the one which could be calibrated for 2 Cylinder

Sure thing Boss. Will surely validate for the compatibility before freezing into a particular model.

Recommendations appreciated for some compatible and best tachos available in the market.

Cheers!
