While disconnecting my damned door buzzer yesterday (after I bypassed my damned clutch starter interrupt) I noticed that the ECU behind the glovebox has a knob on it labelled "RPM" with high and low at either extreme. Does anyone know what this does? Is it a rev limiter?
BTW, I determined via the FSM that my fuel gauge is garbage. Does anyone have an SR5 gauge cluster they'd be willing to sell?

ECU question
It's a scientific fact that in a twin engine aircraft, when one engine fails there is always enough power in the remaining engine to make it all the way to the crash site.

Re: ECU question
I've never seen that, and I KNOW these cars dont have rev limiters, as I've had mine to 8000 rpms, and it doesn't even try to limit it. It'd also be hard to limit revs with a carb.

Re: ECU question
Don't take this the wrong way - but are you certain you are looking at the ECU?
The AC amplifier switch has a knob and is marked just that way. This is visible as you look straight through to the black housing.
See page AC-39 (nearly at the end) of the FSM.

T4WD augury?

Re: ECU question
My bad, that must be the a/c amplifier adjuster. Finally tomorrow I'll have a chance to do a bunch of fact-finding inspection on my new to me car. Might just get into SCCA Rallycrossing next year.
BTW it would be very easy to have a rev limiter on a carb'ed car, just cut the spark. I'm sure there are carb'ed cars with factory limiters, but you can buy an aftermarket under-dizzy cap electronic ignition for just about any car. I believe it's called Petronix, and it has a built in adjustable limiter.
Hope all our NW peeps are keeping warm/enjoying the snow.
