tach installation in 89 ctd

[unixcowboy]

BTW Cap'n,
They are using an IssPro programmable tach. If you are also, then you'll be slightly off when you set the input to 2...Not enough info for the tach.
I - like them - had to tweak the fine adj on the back...The tach was reading ~ 50 rpm off according to an optical tach I have.
But now - it's right on.

OH, the engines not running in this pic that's why the tach show 0 rpm......

Aloha UnixCowboy,

I'm writing from a Linux machine now. Ubuntu.

Regarding the tach, that was a post from a long time ago. I'll have to wind-up the WayBack machine pretty tight to remember the details.

Actually, I don't really care about a 50 RPM difference between actual and indicated. As long as my top RPM is not 8000, then I know I'm driving the right truck.

Aloha, Dean.

Hi Cap'n ....
Long time no hear...

I'll be in your neck of the world ~ 5th or 6th of Mar. Leaving this cold for a couple of weeks.

BTW - I found an 8000 tach that I got working on the Cummins. I just mentally divide by 2 to get my RPM's.

Sure drove a friend crazy when I took him for a ride to show off my new sticks. He saw the tach and thought I was actually turning 6500 rpm

I didn't have the heart to let him believe that so I told him the truth later in the day - but he was sure I'd modified the engine somehow to get to spin that fast...
