Tiptronic gearboxes?
RazMan - 20/6/07 at 09:09 AM

Has anyone used one of these in a kit car? How did you overcome the ecu control issues?

Just thinking of a possible future project

Depends which Tipronic box your using / what clutch system it has. If its from the smart roadster id say forget it. Hence the AC using a new manual box!!

Volvo use a good tipronic, as does BMW. As the police round here both use them with tipronic boxes they must be fairly smooth too.

I know there are quite a few tiptronic type boxes used on tintops - I just need to know if torque converter settings can be adjusted to compensate for the sudden loss in weight when used in a lighter car. Also modern security and emissions systems often make it very difficult to use the original ecu and all of the aftermarket ecu's that I know of would not be able to control the gearbox.

I would love Tiptronic boxes in my two kit cars.

Kind of like having a sequential box without the cost or having to put up with the limitations of a bike engine .

As you say sorting out the programming is the problem - I think the manufacturers of aftermarket ECU's would be best able to answer whether this is possible.

Also - not even the big car manufacturers can get it right every time so what's the chance that the likes of you and me will get it right.
