Speedo healers ?????
Discussion
Okay I've got a yamaha r1 engine in a mini just wondered which is the best speedo calibration chip ??
They don't seem to sell them in the uk and seem expensive for what they do ?? Think its biker discount store is the only place that does sell them ??
Any help wound be grand thanks
Plus if anyone has one lying around ;-)

I've got a HealTech one. Very easy to fit, especially if you order for you specific engine it plugs straight into the speedo sensor wires plus live and earth. Adjustment is easy, with large adjustment range. I got mine second hand so can't help/recommend sellers.

Previously I had a "YellowBox" one. That was limited in the adjustment range and only just got mine within the +10% legal margin. It'dbe ok to improve the setting on a bike but couldn't cope with the amount needed to account for the diff ratio in the car.

As mentioned, a rough idea of the adjustment range you need is the key thing to identify - some of the boxes simply won't go far enough (being aimed typically at +/-10% for bikes to compensate for a tweak of sprocketss etc).
I've an R1 5PW engine in my Fury. The bike's final drive is about 2.5:1 vs my diff at 3.38:1, and that's multiplied by the difference in tyre diameters (205/60r13s on car). It meant the speedo needs a 28% adjustment. I think you'll need something comparable depending on the FD you choose. Mine's also a yellowbox unit, with a widerange setting - it works well.
