Let me tell you what Melba Toast is packin' right here, alright. We got 411 Positrac outback, 750 double pumper Edelbrock intakes, bored over 30, 11 to 1 pop-up pistons, turbo-jet 390 horsepower. We're talkin' some fu*kin' muscle!

The gauges look good. What car?

Yeah, I have a cowl induction hood - with NON FUNCTIONAL GAUGES!! HELL YEAH - FieroRice

looks to be a buick riviera? am i right?

Yep its 1990 with a 3800. from what I know all of them "rivieras" have some sort of touch and digital clusters

It is worth a try, I looks very nice. (The gauges that is)

Anybody have a service manual for a 1990 Riviera? If the gauges have an analog to digital converter built in then you are in luck. If not you better be smart in programable microcontrollers and assembly language. Beyond my capabilities, but they look cool.

Riviera??..
I woulda guessed a Reatta. I love those little cars.

We have the owners maulal for both the regatta and the riviera here.

I don't think the owner's manual would have any information relevant to a swap. The service manual would have the detailed schematics to show how the gauges are integrated to the rest of the car.

If the gauges are wired directly to the senders, and the senders are the same or similar to the Fiero, then it would work. If the gauges are talking to the ECM or some other module with a digital signal then if would be a lot more difficult to integrate the gauges to the Fiero senders.

With the firebird, the gas gauge is the only gauge that's digital and refuses to work with the Fiero sender.

The gotcha is likely to be the tach. In many of the 88+ cars the tach signal comes from the ECM ALDL data stream, not the ignition module. The Fiero can't supply the correct data stream.

If that dash gets the tach from the module, then you might be ok. The speedo signal will be the next hurtle but not unsolveable. The speedo signal again probably comes from the ECM (but this time a 4K PPM output rather than the ALDL data stream).

After that, you should be home free.

I have one from a Cutlass International. High cool factor. Sometime I should do something with it.

A note, if you are running the 92-95 3800 ECM's I can change the stream to send out the right tach signal if you want to try and install one of these various clusters.

I agree the tach and the speedo are always going to be the tricky ones.

By the way, if you are going to do a gauge swap of ay kind you probably want to get your hands on a speedometer from an 88 because they have the 4000 PPM buffered square wave output to the electrohydraulic power steering.

That's what I'm using to drive my firebird speedo and it's rock solid. I have heard that trying to use the output of the VSS to directly drive the speedo can cause it to operate erractically at low speeds.

I have the Mitchell on demand for the '90 Riviera. I can check the wiring diagram tomorrow and see where the tach feeds from. As far as the speedo sensor goes, I'll see what it shows there as well. I agree, if it would fit the bezel, it would be a unique and neat look to the Fiero.

There's one on a GM 87 cavalier Z24 the tach is easy to calibrate just change the cap. as you do in the fiero and it is a stand alone unit as it the fiero unit and uses standard GM sensers for the gauges.

Terry is correct. There's a guy in our club that installed on into his car and the tach will not work. But, everything else seems to be OK.

Riviera and Reatta have the exact same dash. I have a Riviera and the gauges are really cool. I believe it's BCM controlled so a swap into a Fiero will be virtually impossible. A lot of the Reatta guys can't even do an engine swap because the electronics won't work with a non-stock motor.

Another cool feature of this dash is you push the test buttom and it shows if all your warning lights,etc are in working order.

Our riviera is slammed with features,factory cd player,doors lock when you remove the car from park,full leather interior,lumbar seats.

Every power option known to man and 350k on the clock with no problems aside from an alt.Very reliable car.

Difficult but not impossible. The Firebird gauge cluster is a virtual drop in compared to this though. If you have to simulate the the BCM it would be very complicated, but not impossible.
