Heres a link to a porsche site where I found software you can use to 'dyno' your car for almost nothing (less than $5).

Havn't tried it because Im too busy with work, but will do asap, anyone else tried it or who does try it, let everyone know if it works!

I've used a similar set up before, and results were quite accurate

how does it work? is it similar to the gtech or is it a totally different thing?

it analyses the sound of the pulses sent from the coil. From the data that you put in regarding weight, tire size, etc, it can determine how much power you're getting to the ground.

Sounds like a good idea. You can download the zip file from the site as well as a wiring diagram for the voltage divider.

Once you've got the zip file ($0) all you need to do is make the voltage divider (approx $5) and you've got yourself your own personal in car dyno!

I might have to give it a try

Please let us know how it goes because I'd love to give it a shot but just dont have the time. Be a good DIY article!

It works about as well as a Dynojet as what you are making is a inertial type dyno.

Beware, road gradients and headwinds throw the numbers off big time.

what is the voltage diver..
I read it.. they mentioned about it..
but they said all you need is just a wav file.. ( i only read the main page)

The voltage divider listens to the pulses from the coil and tones down the voltage to an acceptable level that the computer can handle.

It should basically work like this:

Coil --------> Voltage divider --------> audio in on your laptop

i think thats wat rival F1 teams do aswell.. they have ppl around the track that listen to the cars with all their high-tech gadgetry and they can find out wat kinda power output they have and if the engine has been turned down.. pretty amazing stuff
