Re: Speedo Correctors
I took one for the team and laid out $39.95 today. 
Unit has 4 wires. 2 for DC supply, 1 input and 1 output, which may make VR inputs difficult to accommodate.
I have attached a scan of the users manual and a photo of the board.
The back of the board has a SMT PIC controller.

Re: Speedo Correctors
interesting...... it does have an AC output option ... I can only assume you are supposed to wire the other pin to earth for AC ?

Re: Speedo Correctors
The AC coupling link applies to the output.
Will try to bench test tonight and report back.

Re: Speedo Correctors
just looking quickly at the components it could be an updated design of the original Silicon Chip/jaycar corrector with surface mount PIC chip. The part number on the board is KC5435 which is the same as the old DIY kit from Jaycar..

Re: Speedo Correctors
Having played with this thing a bit, I have to say I am a little disappointed.
Firstly, the input and output wires were reversed on the board. Took some head scratching to discover.
Secondly, even when set to zero correction, if you slowly sweep the input frequency, the output is very 'notchy'. When connected to the speedo, you can see the needle jump as the module tries to keep up with the varying frequency.
Not as noticeable as the frequency gets higher, however, sadly my speedo does not spend much time around 200KPH.......

Re: Speedo Correctors
Did it look possible for it to convert from reluctor in to hall out?
