Question About New Techart Convertible Top Module

[jcopella]

I just installed the new TechArt cabrio module (2003+), which is advertised to allow operation of the top without the handbrake (up to 25mph) and one-touch auto up/down.

The handbrake hack seems to work, but the auto up/down is not -- I have to keep the button depressed the same as before, with the stock module.

If anyone here has the new module, can you confirm that the auto up/down feature is working for you? I'm trying to determine if I have a defective component, and I haven't heard anything yet from TechArt or my reseller.

I have the bahntech unit, not the techart, but the issues are similar I guess.

You need to hook up the speed sensor wire and perform 2(!) relay hacks.

Some questions to ponder:

- Are you 'tapping' the button? Keeping it pressed reverts to normal operation.

- Also, did you connect the speed sensor wire to the techart module?

- And did you disable the speed sensor input from the cabrio relay?

- If not, does it work when you are at a full stop (with or without handbrake)?

Lastly, is the latch handle pulled all-the-way back when you try it?

<{POST_SNAPBACK}>

According to the instructions (which are in German, so I might be missing something), the relay module is plug & play. You take out the old control module and put the new one in its place. I don't think it's necessary with the TechArt piece to re-wire the speed sensor.

To answer your questions, yes, I am 'tapping' it. The button will retract the top with the handbrake unengaged (car either in motion or stopped), but the button must remain pressed the whole time.

I think the BahnTech is a different design. Appreciate your feedback though. I may end up going with BahnTech unless TechArt comes thru with some answers soon.

Do you know if the BahnTech works with MY2003?

Check with SmartTop.

I vaguely remember that when TechArt introduced the new top relay for MY-03 and newer boxsters, they also reduced the pricing (from $600 to $300). I haven't looked into it, but it sounded to me as if TechArt is simply reselling the SmartTop relay. (SmartTop is pure plug and play, replace the double relay).

The original TechArt only works with Boxster that are pre MY-03. MY-03 and newer still need the touchtop/autotop etc. to give you the automatic top/down feature. If this is the module you have, then the feature is not available.

Check with Omar and Dutch Guy on the ppbb board, I think they both have the TechArt in their car, but I don't know what year their cars are.

Do you know if the BahnTech works with MY2003?

The Bahntech unit is is a simple "hold-switch" circuit, that mimics you pushing the button longer, and is not sensitive to the 02/03 changes that were made. As far as I understand it, it should work with all model years. But contact the Bahntech guys to make sure of this. Edited October 11, 2004 by HenryV

Hi all,

just a quick announcement: the smartTOP modules are now officially available in the United States. You can find plenty of information on our web site www.smarttop.de (english available). All smartTOP modules are Plug-n-Play installation with no soldering or cutting wires.
