Patrick, just curious as to what year and engine the tach in your pic above is from? I noticed it has an oil pressure gauge built into the lower section of it. I do know that the tach in your pic is not from 86-88 GT cars. Kit




That’s an 85 V6 tachometer, either SE or GT.

I'm not sure, but these tach boards for 4-cyl, V6, V8 may be his.

Kit, I have so much Fiero stuff here that I have no idea where/what this tach was originally from. Judging from the red line, it would not have been a duke. So it would've been from a V6 Fiero that did not have a center console gauge cluster. Possibly an '85 GT?

[EDIT] I just noticed this post...

Tony, judging from the discussion in This thread, I believe Chris moved on from the project... although he did say that one of the boards was of his design.

Thanks Patrick.
Ironically, my silver Fiero is an 85 GT. However, the cluster swap and aux. gauge pkg. was one of the first things I did when I got the car. I do remember that the original one had the 85 mph speedo but I don’t remember (when I swapped it out) that it had an oil gauge at the bottom. Now that I think about it, I probably have the 85 cluster stashed in my garage. I just forgot about it. 😊

In my case it's the basement where I've stored most of my stuff... but yeah, I have the same problem!

I did have a project some years ago for a replacement tach that could do oil or not, it used a Microchip PIC to drive the movement. If someone has experience with embedded programming and electronics, I would transfer what I have to you to take over.. please contact direct, I do not get on the board very often any more. ceddy@nb.net.
