There were many reasons for the change of the site software, the biggest was security. The age of the old software also meant no server updates for certain programs. There are many benefits to the new software, one of the biggest is the mobile functionality. Ill fix up some stuff in the coming days, we'll also try to get some of the old addons back or the data imported back into the site like the garage. To create a thread or to reply with a post is basically the same as it was in the prior software. The default style of the site is light colored, but i temporarily added a darker colored style, to change you can find a link at the bottom of the site.
Oil Temperature gauge

I figured you didn't want to discuss the pros & cons of why or why not, but now you've asked..... I thought about it, & talked to a few of the local race bike engineers here, who collectively convinced me there was no real point or any benefit to be had in fitting that type of gauge....... :dontknow:
If I can pass on their explanation coherently... basically, it comes down to these engines being dry sump motors with external oil coolers, all computer monitored & controlled; so there's not going to be all that much 'helpful info' for the operator to be gleaned from an oil temp or oil pressure gauge.... the major point being that your oil temp (& pressure) is either going to be controlled & safe, or it's not - and if something breaks/gives up so that it's not, then your check engine light IS going to go on pdq & you'll very rapidly be dumped into limp home mode or the engine will be shut down. And that process is going to happen in less than a second of the oil system &/or cooler not keeping the oil temps & pressure within the specified 'safe' parameters, which is likely to be well before you'll be able to notice & react to any changes in the info shown on a gauge. :lecturef_smilie:
But there are apparently quite a few places you can tap into to get that info to a gauge - altho the biggest risk with that is that by tapping in anywhere, you'll upset things enough to kick off one of those warnings & trigger limp home mode.... So if you REALLY want to see that sort of info, you might be better off tracking down a Scan-gauge or similar that can read all the electronic info which is already collected & used by the system, and work out how to display whatever bits of the collected info are going to be of most interest or helpful to you.... :thumbup:

really not looking at tapping into any electrical system on the bike-not necessary.
Power for the gauge coming from a switched circuit is no big deal..
The hard part is where to install the sending unit.
I have done water temp installs many times and the source is easy-install the sending unit in a radiator hose.
Not so easy for oil. Can't think of a place to install the sending unit. With many engines there is a threaded hole to use for the sending unit. Not about to tap a hole so I'm thinking I should find another project.
Was hoping to see if it had been done, guess not.

Go here for Oil PSI Gauge info on a Spyder.
http://www.spyderrt.info/
Go here - Randal has all info, and what to do. Not so hard. And relatively inexpensive.

I LOOKED but could not find "Oil Temp" just pressure???
I found "oil pressure" Not oil temp.???
I found "oil pressure" Not oil temp.???

As I see it.....
The trick is finding where the sending unit for oii temp is on the spyder. Now a simple TEE off an exisiting oil line or the oil pressure sending unit would get you a reading but you really need to be reading at the hottest point. Should not be that hard to do but more than likely will not match the readings and results from the spyder's measure...:thumbup:

There are oil pressure and temperature sensors in the Hydraulic Control Module, Based on what I see in the parts list the HCM is apparently sold only as a complete unit and the sensors are not removable. That's the only oil temperature sensor I find in the service manual. Here's a blurb about the temp sensor.
