Speedo drive.

Does the wedge use a manual drive or a speedo transducer.

Thanks

Cable.

If you are looking for an output for your race logger gear then the hotwires have a widgit that produces a signal for the ecu. The speedo drive feeds into it then another short drive cable goes back out to the speedo itself. I have no idea if it produces a pulse or rising voltage but you might be able to get hold of one to retro fit to a flapper car.

Aye, I'm still trying to find one to try on my cruise control. At the mo I can have cruise or a speedo but not together (the SD1 electronic speedo drive replaces the cable drive at the gearbox)... there is a guy on Ebay with them but he wants silly money.

This is for the Race Car.

The Gearbox I have seems to have a manual drive (95% sure is a 400SE Gearbox.) but I'll be running an Emerald ECU and Digital Dash, so need an eletronic output, there was some LT77 gearbox's that had speedo transducer's, hopfull I can retro fit to an older gearbox.

Just wondered if anyone knew, us won't be able to get under the car tonight to look.

Don't bother with the gearbox. Add a wheel speed sensor to one of the front wheels. Easy to get at and gives a better indication of true road speed.

ok will do thanks steve.
Was not that overly bothered to get it 100% as will be have a 10mhz gps speed output also.
Was mainly going to be a backup, if the DL1 failed.
