Microtech causing tacho to read wrong RPM
 

Hi,

Can somebody please tell me why my LT8 is causing my Tacho to read only half the RPMs, The RPMs on the Microtech handset seems to be correct but my dash reads half of the handset RPMs until i reach 6000rpm which is reading 3000rpm on my dash it will suddenly jump to match whatever the real rpm is, so it reads half up to 3000rpm then jumps to 6000rpm. I hope this makes sense. I know its the LT8 because when i plug my old Mt8 back in its normal. I'm still using the same loom from my MT8 and just plugged the LT8 into it.

Cheers

Well the loom/wire harness could be slightly different. But i just got done installing my LTX12 and my tacho reads way HIGHer than what the laptop says. But on another thread in here a guy informed me that if you take the instrument cluster apart there is an adjustment screw.

So I suggest letting it good and warm and adjust the that screw so that it reads the same rpm at idle as your laptop/handset.
