PLEASE: If the links, are in some way against the rules, just do me a favour and delete them and not lock the thread! Guys, I've wanted some guages for quite a while, and like a magpie, I always seem to be drawn to the shiney-shiney, most expensive toys. Defi is no exception. However, I've found a solution which is much more pleasing on the wallet. Thats this: http://www.defi-shop.com/product/dp/dp_top.html The Defi Link Display. Obviously i'd need to purchase the control unit: http://www.defi-shop.com/product/cu2/cu2_top.html ...but those combined some in at around £280. A lot for a guage you might say - but the display, with the control unit will do: -speed -oil temperature -water temperature -oil pressure -fuel pressure -exhaust temperature ...and with the individual guages starting at around £130 ea - thats a considerable saving. Now - the last bit of the jigsaw is sensors. I've had a look at the Demon Tweeks website, and the prices are quite high. Surely, with a little [insert electronic components shop here] fiddling, something could be rigged up a little cheaper! Now - does anyone have any experience with Defi kit, and the sensors, the type of connector, and the sensor types? I would have thought there wasnt much difference in 12v sensors for automotive applications (except range of measurement and accuracy obviously). So - anyone able to help/suggest anything?
