Tachometers

Where are they going to source the rpm signal from?
The alto is distributorless, no?

The only problem is atleast in the stock room attached to the M.A.S.S outlet, they will not sell compnents over the counter. So one will have to get it fitted at the dealer itself.

Hey, could you gimme any more details about tachs starting at 1500 price range.. as in are they available for a 4-cylndr Zen and whats brand etc (Bcos i assumed AutoGauge is expensive than that), shift light available ?

Any details would be helpful in where to get them from.

Many thanks.

2" cost less. 3 3/4" is bit costly. however the ones without the shift light cost between 1800-2000 rs. i got mine 3 3/4" with shift light and 7 color display autogauge for just 2300 rs.
it has switch behind for 2-3-4-6 cylinders. works like a charm. very accurate.

I am guessing that the tacho in Ritz and A-star is connected with the ECU as its factory fitted. Getting the tacho retrofitted in an alto or any other car will be not be easy, as sourcing the signal from the ECU will be a tough task with the risk of damaging the ECU unless done by a professional.

getting the source signal in an alto is the easiest thing ever. just connect the signal cable to the negative of the coil. however in wagon R and swift it becomes very tricky.

The MASS would be Mandovi Motors, Gorguntepalya (Yeshwantpur)

Is it actually that simple in the Alto?

So, fitting an A-Star's tacho should be a breeze. The only problem will be to get the backlighting's wiring and connection done I suppose.

amit_mechengg · 18th July 2009, 23:38

no issue on an alto at all. i just showed the electrician how to connect the wires. one to coil, one to accessories point on ignition and one to parking lights and one to ground(earthing). its very simple, even a amateur electrician can do it on alto.
however my electrician was very much talented and he just amazed me. he didnt cut a single wire. he just opened the fuse box and inserted all the wires in the slot , except the signal cable from coil.

just go back few pages and check out my tacho. go through all the pages you will see how easy it is to fit a tacho on alto.

I think thats only if the tacho is a 2 cylinder one, you cannot connect a 4 cylinder tacho to only the coil.

no it has nothing to do with the no of cylinders. it depends on the type of ignition. alto has a distributor coil. swift doesnt have any coil. so you have to tap the signal from the ecu.

Amit,

Did take at your tacho install. You have explained the process clearly which will help Alto owners like me. I like your tacho and also the smaller one in the Zen. I think I will check around BLR to see if the Autoguage ones can be found, else I will place an order for the A-Star one and have that fitted during my next service.

Cheers,
gpa

Do let me know if you manage to get one. Give me the part number too.

Most definitely will. It will take a while though as I still have a while to go for the 20K service. I'll also be checking to see if I can get it at the only over-the-counter MUL spares retailer her in BLR. If he indeed willing to place an order for the A-Star tacho, I don't mind shipping one to you.

Will keep you posted!

Cheers,
gpa

This where both Hyundai and MUL decline. UM

A tachometer is not ABS or airbag!
Sorry again!

Thanks trrk. I was heartbroken that it couldn't be done. Although... my MASS tried very hard, I'll give them that. The senior works manager at my MASS took the tacho installation manual from me, made a xerox, sent it to Bosch, Mico, and MUL, and followed up with them daily for a solution.

Finally, MUL reverted saying it couldn't be done. Which is BS, because it CAN be done... the only problem is that they're probably the only ones capable of doing it, but they won't.

Anyway... such is life. Sigh.
