anyone played with boxster gauge cluster? Options

[skeates]

Hey guys - I'm not sure if this is a subject that has been beaten to death before (I certainly wasn't able to find any threads on it), but has anyone here ever attempted to make use of the boxster or cousin 996 gauge clusters in a conversion? I was able to find a pin-out diagram for the boxster cluster which makes it look doable. Just curious if there was any fancy shmancy communications between the cluster and the ECU that would need to be worked around?

Not that it matters now, since you have been experiencing success with your interface using the Arduino, but what I was referring to with the use of the OE gauge guts was to place the guts behind the gauge face in place of the original, put the Boxter needle on the shaft of the OE unit, and then use the original tank sender. I see this as simple, but not nearly as much fun, nor elegant (IMG:style_emoticons/default/wink.gif) The problems I foresee doing this are possible length of shaft of OE too short, needle wont work on shaft, sweep ark of OE not same as Boxter and thus gauge face will not be correct measurement/needle deflection will be incorrect, OE guts will not fit.

With your initial start up causing needle bounce, is it possible to have a value programmed in to make the needle hold a value consistent with the E at start up? How bout Full and then is drops to actual? Is this bounce of the needle stop due to poor or no signal? Does the stock setup in a Boxter do this, or is this just due to your interface? How about a delay in the interface that allows it to power up before sending a signal to the gauge so that there is no "seizure" on start up?
