Traqmate Users. Where do you get the RPM input?

If you can't pull it off the ECU, you can use an MSD inductive pickup. http://www.msdignition.com/2006/06-22.htm

Just bought several for some Elise and Exige installs. Summit has them for less than $50. It takes the pulse off the impulse wire to the coil pack. Not a direct connection. Works well for the TraqSync, TrachTach or TraqData II.

Enjoy!

It took *forever*, and some serious assistance from Rifledriver, but we got there in the end......

Cheers,
Ian

 

BTW - The problem there is the speed of the bus - It seems to work at a smog test station but we failed miserably trying to feed it to the TM - Never really did figure out why though....

+1 - My VC hillclimb video from last year: http://vimeo.com/4443638

I'll send you the properties file for it if you like [Sorry about the throttle sensor getting overloaded - We suspect that WOT generates a higher voltage when the engine is running than just ignition on - Or, it's a bad channel on the Traqdata.]

Cheers,
Ian

 

Thank you for posting this!!!

 

You're both welcome!

I'm assuming you found the black/brown wire? Behind the passenger seat? In an unused connector?

I actually forgot to put a "use at your own risk" disclaimer in my original response

BTW, the comment on it taking forever wasn't about doing it - That took less than an hour. It was finding the ECU pinout's and acquiring the WSM on CD that took the time - Why do they want to keep this stuff "secret"?

Cheers,
Ian

 

Ian - thanks for posting the tach connection and great video of the hill climb!

I am trying to do the same connection. Any tips on finding the wire? I looked behind passenger seat/under/etc but didn't see it. I am looking in a coupe.

thanks

 

Thanks!

Have you removed the "parcel shelf" behind the passenger seat? - I haven't got any pix unfortunately, but once you pull that cover off all will be revealed. It's mounted with 4 pretty big stainless steel Phillips head bolts. [Be very careful when putting these back as they're soft and easily cross threaded.]

There's a bunch of relays - one of which is for the brake lights which we tapped in to. On my car (an '02 360 F1 Spider btw) we found an unused, 4 pin connector just "laying" there doing nothing [This was confirmed by the WSM CD BTW] - One of the wires going in to it is the black/brown [Meaning black with a brown tracer btw] RPM signal wire - As I said on the Traqmate site, we tested it by simply "poking" the wire from the Traqmate RPM input into the appropriate pin on this connector - The Traqmate immediately read 520 RPM [Half of the real value, but that's a settable parameter in the Traqmate - IIRC, I set it to 4 cylinders and all reads correctly.] Once confirmed, we used a suitcase connector to tap into it - Easy-peasy!

BTW - This black/brown wire is all over the place - It goes to *lots* of places - Any of 'em *should* work.

I will say again however, "use at your own risk!" - I have no idea if the wire colors stayed the same across model years etc, or even if the connector is used in other models..... Having said that, I reckon, but don't hold me to it (!) that if you can find the connector, and it has the appropriately colored wire, give it a try - Worst case the signal's not there.....

Good luck!
Cheers,
Ian

 

Ian - thanks for the details. I did get the shelf off and took a look and while I found an unused 4 pin connector but it does not have a black/brown wire in it. Mine is a 430 so it is probably set up slightly differently. I do appreciate the help -- thank you.

Now you've got a problem Ideally, you need your ECU pinout diagram - This lists what pin(s) have the data but is not widely available [Don't ask!] Then you need the WSM (on CD) that shows wiring colors, connectors, and where they go etc - It's actually very cool..... If you have a friendly tech nearby they typically have the CD & dongle required to open it (!) - You may get lucky and see RPM on your unused connector in there.

Or, you could buy one of those MSD transducers Peter mentioned!

Cheers,
Ian
