Click on the linky provided in the first post and see. Its only 279 US$. Think its worth every penny

Click Here GTech-Pro Model SS

That's without the shift light. Think our old snake will throw in a discount for 2 of these?

279$ for the basic kit. Everything else is optional and jacks up the final price. 320$ for the one with the shift lights.

Are the older ones available in India? Any idea about the price?

From the pic looks like the Digital and Analog are not in sinc right?
Analog-8k rpm
Digital-7456 rpm

one thing i just dont get. how does it pick up rpms from the cig lighter, and accurately?

That was on the ss and rr models,its there on the site .. some tech.PRetty accurate though,seen it on vikrams swift.

This one doesnt connect to the ciggy lighter though.

Yeah somethings definately wrong,the video shows both in sync though.

where does this connect?

Wherever all tachos normally connect Says it can read rpm off obd.

Its a frequency meter. Your DC voltage has slight "AC" component. This is the case with all alternators.
However if your alternator does not spin at the same speed as the engine(rare case), you will get wrong reading.

aah.. thanks tsk. but its probably quite a feat to get it so accurately. tried vipers gtech in my innova. just a litle calibration and it was as good as the stock tacho.

It actually depends on how clean is your DC circuit. Many high end cars have effective AC blockers which clean out most of the AC component out of the circut.
No need to worry for cars south of 10L.
When its plugged into the DC socket, the first step is a Capacitor in series, which takes removes the DC component.
After that comes a high precision amplifier(this is the expensive part) to boost the AC signal. I presume a 20X Gain is needed.
Next step is a frequency counter. This is a simple circuit.

I am sure, give Navin a few transistors/op-amps/capacitors/resistors, and he will give you a rpm meter which is uglier than hell and as accurate as Gtech, and costs less than 20$
