I called Univair because I may have ordered the wrong tach cable which I did because it is not PMAd for a Cub. I asked one of their tech people about the difference between a recording tach cable and a non-recording tach cable. He did not have a good answer except that they are all the same and PMAd for different models. I do know that the non-recording cable is a bit cheaper. I have a recording tach that I just got back from Keystone. The only reason I am asking is because I have a picky IA.
Also, they have a non PMAd tach cable listed for the J-3 which is $88.00 compared to the PMAd cable that is $120.00
