As far as I can tell a rally 'computer' is really just an accurate odometer and stopwatch right?

I'm leaning towards one of the new Monit TC100's, they about the same price as a terratrip but 1/10 the size/weight. They look a darn site more modern too. Anybody have experience with them. Its not for me either way, its the co-drivers toy :lol:

Interesting.
They look the business. I've only ever used TerraTrip and that was ok.
As you say, it's a co-drivers toy, not mine. :P

Might be interested at the right price. :)

Only downside I can see for my car is the sensor setup.
RS legacies have a cable driven speedo and mine has ABS so makes the wheel sensor impractical.

They say you can use the probes from other rally computers, so I'm guessing the terratrip gearbox probe should work fine. The TC100 is $630inc

That would work if I had the gearbox probe. It's on the previous rally car. :P
So it's a similar price to the Terratrip, just a lot lighter. :)

They are great.

Use your electronic speed sensor if you have one and they're easy to calibrate from there.

For cable driven I guess you could try an old mechanical HALDA, I may be showing my age...
I don't think you can buy them anymore.

Pretty sure you can buy the cable sensor for the terratrips separately. I know I used one for the terratrip in my previous rally car.
And it ran the same type of gearbox as my current rally car. :)

Yep, terratrip do an cable sensor that works on most Jap cars, including mitsi's so that would be the way to go.

Am now driving but am a vetran of over 200 rallies as a navigator/co-driver and over te years I've used most - for me its the Brantz Laser 3 every time - all the fuctions of a Coralba at 1/4 the price, nice and lightweight, easy to set up, freeze time of day clock which can be oh so useful on stage finishes etc fuel guage if you want it, average speed for regularities and road sections, does everything but call the notes for you.

The most commonly used rally computer is the TerraTrip. It comes in several models such as the 202,303 and 404. I think the 404 was discontinued but you can still get them. They measure/record TSD info. I think they start out at around $200-250 and the more expensive ones go up to 400-500. I'm not totally sure about the prices but those are roughly accurate. You also have to purchase
sever sensors that i think go somewhere on the axles that measure speed and distance, i'm not positive about this, anyway you can search for info about them on the WWW, just search for terratrip, hope this helps.

The sensor should pick up from an undriven wheel where possible, to avoid reading wheelspin. I have a terratrip 303+ with proximity sensor "seeing" the back of the wheel studs on a rear hub. Callibrated using Tomtom satnav speedo on a flat straight road. match terratrip speedo to tomtom.

Its a few years since I did it. From memory I made a Z type bracket mounted probably under a calliper carrier bolt head. Adjusted clearence to pan heads of wheel studs. I ran the lead through a length of smallish bore nylon push fit type air line to protect it.
Hope to see you at the Rymoor (no seeded entry list yet???) S
