RPM GAUGE SHOW DOUBLE RPM

Idan24 · Dec 16, 2020

my fox's rpm gauge shows twice as much as my autometer, when my autometer rpm shows 1000 rpm, the instrument panel shows 2000 and consecutively

General karthief · Dec 16, 2020

So which one do you suspect?
Does the autometer tach have a 4-6-8 cyl switch?

Idan24 · Dec 16, 2020

I don't really know if it has any swich, it's a
autometer cobalt https://www.autometer.com/5-tach-10-000-rpm-shift-lite-cobalt.html with shift light, I know that what the autometer shows is correct, because I already Check the rpm with a Timing light

What year/engine size?
What does the tach red line at?

Idan24 · Dec 16, 2020

1993 5.0 H O , red line .... 6000

Before the autometer tach ,what did factory tech read say at idle?

Idan24 · Dec 16, 2020

my fox is 1980 with full swap of 5.0 h o 1993, I don't know if in its past it was automatic, recently installed T5

He shows rpm, but shows triple the actual measurement

That' a 4cyl tachometer.

You'll need to find a 90-93 V8 tach (7K redline) and swap it in.

The body is a 1980

Right, but he said it's been swapped using 1993 5.0 HO guts and cluster

Idan24 · Dec 17, 2020

Is it possible to modify this, some resistance or something to make it work?

Anything's possible, but the odds of someone having done this and having the info handy are slim. You'd likely be paving the way.

Easier to swap the tach, but you'll have to get your hands on one

Idan24 · Dec 17, 2020

the connectors of the new v8 instrument panel are the same, or it's time to make adaptations

Sorry, I didn't read it that way so lets get it clarified
Is this a 80 model body with the 93 dash swapped ?
If you need a 87-93 V8 tach I may be able to help.

Some of the early model factory tachs had a switch on them to change for v8. Might need to pull it and check.

yes, it's a 1980 fox, with a 5.0 h.o swap engine and 1993 panel instrument
