Hi all, just thought I'd give an update on this as I decided to have another go at it yesterday. Pretty certain I cooked the meter movement, so I grabbed the other tacho meter movement and did the resistor mod. And it's all working now! :)))

Tried this. Also confirmed the meter movement only goes one way. Had the needle sitting perfectly at 3k rpm using the pwm trick! But then I went to start the car to take her for a spin and make sure the coolant temp gauge and oil press gauge is working fine, and I’ve attached a photo of what the tacho was reading at idle, it’s a way off unfortunately I’ve put the dash back together cos I’m taking the car for a wof tomorrow so kinda stumped now, my only idea is I’ve damaged the meter movement from spinning the needle around to get it to sit perfectly at 0 when I changed the tacho face? cheers for all the input everyone, I might have another stab at it this weekend :))

Cheers guys, will give the above a go when I pop over to my storage unit on Friday :). I'm pretty certain I didn't install the meter movement upside down as I believe it only goes one way but I can check that tonight as I've got my old cluster at home.

Yep when I pulled the original cluster apartment to grab the meter movement out I saw it was just the resistor mod. I took the meter movement out and changed the faceplate and needle to the new cluster one (I swapped from a Zenki cluster to a Kouki one which is why I had to pull the meter movement and needle off). So I reckon removing the needle/meter movement to swap the face plate and needle may have done something?

Hi, I swapped the cluster in my AE86 last weekend and my tacho stopped reading correctly. I made sure to swap over the tacho motor/controller over from the old cluster as it was modified to work eith the Link. Any ideas on how I can get this working correctly again? It does the sweep on key on, just reads like 100-200 rpm at idle (link software says 900-1000rpm). Played around with the multiplier and it got the idle accurate when I changed it to 1.5 (originally set to 1.0) but it's not accurate when I rev it out. Any tips would be appreciated Thanks.
