Hi Mate, Back in the 80's I was buying tachos from K-Mart and converted them to use on Go-Carts.
I can't remember at this stage what circuit I used.
To calibrate them I used my signal generator.
Have a look on google and you might find something.
Some younger brain on here should be able to help.
I will have a look in my old paperwork.
Cheers
Kevin
