If you’re looking to breathe new life into your classic 1978-88 Oldsmobile Cutlass, the MHX Systems are a game changer. These bad boys fit right into the stock instrument bezel without any need for modifications, which is a huge plus if you want to keep that original vibe while upgrading your ride. Trust me, once you see what these gauges can do, you’ll wonder how you ever drove without them.

First off, let’s talk visibility. The fully lit needles and backlit faces make it super easy to check your speed or RPM at a glance, even in bright sunlight. The LCD message center is a nice touch too; it keeps you informed without cluttering up your dashboard. But it’s not just about looks—inside, you’ve got precision stepper motors and solid-state sensors that deliver accuracy you can rely on. It’s like having a modern car’s tech in your vintage ride.

Now, onto the nitty-gritty. The analog gauges cover all the essentials: speedometer goes from 0 to 120 MPH (or 0 to 195 km/h if you prefer metric), and the tachometer tops out at 8,000 RPM. You’ve got oil pressure readings up to 80 psi, water temp from 100 to 260°F (or 40 to 120°C), and a fuel level gauge that shows you exactly where you stand—whether you’re full, half, or running on fumes. Plus, the voltmeter keeps an eye on your electrical system, showing a range from 9 to 17 VDC.

The digital message center is packed with features. You can track your odometer, set dual trip meters, and even keep tabs on the time. For the performance junkies, there’s a 0-60 MPH timer and a quarter-mile timer, so you can see just how fast you really are. The auto-contrasting LCD display ensures you can see everything clearly, day or night, thanks to the LED backlighting.

And let’s not forget about the built-in indicators. You’ve got everything from turn signals to high beam alerts, and even check engine lights, so you’re never left guessing. If you need more indicators, there’s room to repurpose some unused ones, which is a nice touch for those of us who like to customize.

Included with the system are all the necessary sensors: a water temperature sensor, an oil pressure sensor, and a cable-driven speed sensor to replace your old speedometer cables. Plus, you get a set of bushings to fit various thread sizes, so you won’t be scrambling for parts when you install it.

Calibration is straightforward too. Just mount the included pushbuttons in a convenient spot, and you can easily set up your gauges and access all the info in the digital message center. It’s all about making your life easier while you enjoy the ride.

In short, the MHX Series from Dakota Digital is a serious upgrade for your Oldsmobile Cutlass. Engineered and manufactured in Sioux Falls, South Dakota, this system is backed by a limited lifetime warranty, so you know you’re getting quality. If you’re ready to take your classic to the next level, this is the way to do it.
