So I'm installing a jaycar Speedo corrector in my vs tried it before the ecu but cruise control was having a hissy fit so putting it after ecu between cluster I'm on the right pin out c12 but can't get to work now. Anyone had this issue

A common problem many have discovered , the new jaycar speedo corrector kit doesn't work to well. Not sure what people are using now.

It should work once you get it picking up the correct output type

It worked fine before the ecu but I want it after as it was making the cruise control absolute shit

I had to add a pullup resistor before it worked for me after ecu. even then it was jumpy and terrible.

My VDO corrector works great.

My speedo seems spot on with a 10% correction with diff and tyre size change.


My cruise won't work but I think its unrelated as it didn't work without the corrector either. My ECU is happy as a pig in mud with it and the speedo itself too.

wasn't cheap though, about $400 iirc.

Out of interest I've used the Dakota digital SGI5E (from memory)
Awesome unit with signal conversion between hall and reluctir both ways with pulse correction. Only $160 from Australian stock last time.

That looks like a nice unit, just had a look and it's $80 on amazon atm.

I have a healtech speedohealer unit. Very compact and easily adjusted. gave up on the jaycar units.
