I have a jdm itr cluster that shows km/h and goes to 180

is it possible in theory to modify or recalibrate kilometer to mile speedo?

it has yellow gauges and I don't want to swap the usdm cluster and swap gauges.
theres a high chance to mess it up with needle swap.

 

Nope..You just get a usdm cluster or understand the km/h to conversion rate. It's really not all that difficult to do. Just look at the major speed points. 100km/h=60mph, 120km/h is about 70mph, 140km/h is around 80mph.. 180km/h is a ticket :-) (it's actually about 110mph)

 

why not?
theres a potentiometer on the circuit board whats that for?

the speed sensor is same for all us jdm and uk isn't it
so they all get same signal

I wanted something for my jdm cluster a few years ago. I played around with making a 5/8 pulse divider but it's an oddball ratio to hit without a microcontroller (which I didn't want to use for simplicity's sake). I pretty much decided to use one of these whenever I get back on it, unless I have an A-ha diy moment.

The bonus is that your odometer will also be converted if you go after it electronically.

 

You must use an electronic screen interface to do it. I don't understand why you can't use your old noodle is all.

Had a JDM cluster for years, and go across the canadian border on many occasions. It doesn't take long to get used to.

Sometimes the best "signal" is your brain.
