dont mind the looks. will it also show the hp and torque and give timings?

[tsk1979]

Nope it will just tell the rpm. For all the extra stuff like hp and stuff, I am stumped howcome just the DC socket can suffice.
DC socket just gives indication of rpm of engine, and unless you feed in the torque and bhp curve as input data, there is no way of knowing bhp and torque.

[Akshay1234]

it wasnt very accurate either. but it had a gforce sensor that put on the timer when it detected a launch.

[GTO]

The Gtech is best for 0 - 100 times, and you will be surprised at it's accuracy. Usually within 1 - 2% of the actual.

P.S. : Whoa, the EGS looks HOT!

Worth a try what ssssssssayy??!! (the ssssss does not denote a blow off)
Yup, the shift lights are extra, still worth it i feel.

....which will probably give you frequencies and some other readings regarding the ice install in your car too

From the rate of acceleration (determined by the accelerometer), it calculates velocity & G-forces, using which (in all probability) it calculates indicated or mean torque (via lookup or reference tables), thereby calculating BHP by our known formula, horspower= max. torque X RPM at which it's attained at, divided by the constant 5252.

Bah. Forget the simple stuff.

Tried ordering the RR once, but Tesla asked for faxes of proof of identity, & copy of order form that they send you- besides the credit authorisation, that is. Too much hassle. $320 is fine for the fully loaded variant. About 16G's INR. Landed cost.

I want one. Whom do I ask?

[Tool]

getting one with shift light and obd II module.
should be here feb 12th.
will keep you guys posted.
i cant wait now!!!

[Akshay1234]

tool - make sure your esteem will support it properly. people have tried using things like scan gauge but they didnt work. IMO you borrow a scanner from someone else and see whether it works properly on an esteem otherwise your money will go to waste.

[Tool]

Thank you bro akshay , thats a good point.
i did think the esteem is odb II. will check this out for sure.
Guru's? any words of wisdom?? please help.
just told my aunt today to order.will have to make changes to that order really quick.
thanx in advance guys

[Akshay1234]

i know that obd2 things like scangauge dont work on the baleno. in that case it probably wouldnt work on the esteem either. then instead get the obd2 thingy and keep it for your next car or get the accelerometer instead.

[Tool]

Thanks for the idea bro.. will do just that. killer idea.
ordering the accelerometer as well.
hope the obd thingy works.
just checked my mail. order is already placed so im stuck with it. hehehe.

So if you are not an expert and can't accelerate the car to the maximum possible speed, the reading will be incorrect.
So it will report the amount of bhp and torque you are able to extract out of engine. Fair enough I think.

That's not a rare case. On the contrary. Alternators spin at different rpm than the engine.

This means you always need to have a working tachometer to calibrate the Gtech, or you need to know the ratio of engine speed to alternator speed?

[ananthkamath]

Either the tach works off of the signal from the obd port (more likely) or it somehow gets the inductive pulses (like a timing light) from the cigarette lighter port (less likely).

Either way I doubt this is good value for money when the same company offers more serious (and less ricey) solutions for about the same money.
