Maintaining on-site technical support means you get answers to complicated questions quickly and from technicians that helped develop the products you install. All settings are based on 1/8-inch slack in cruise control cable. More slack will cause the cruise control to surge or lose speed once set. RF steering wheel-mounted switches can be installed on several vehicles, but are not recommended for every vehicle.

Troubleshooting & Technical Tips

This one set me back $US 180 from Performance Buyers Club, again not counting shipping costs and those forever accursed Canadian taxes. The servo module on this (possibly newer) model is much smaller (4"x 3") and seems to be very similar in size to the factory unit. The owner's guide states that it is a Rostra cruise control modified by Performance Buyers Club specifically for the Miata. Add an aftermarket cruise control kit to your ride by choosing one of many universal cruise control kit options from Summit Racing!

Rostra sells its products through an extensive distribution network that includes Original Equipment Manufacturers, expeditors, mass merchandisers, regional mobile electronics chains and independent specialists both domestic and internationally. I have been very satisfied with this product since I have installed it. Going up hills, the cruise control accelerates appropriately. I definitely recommend adding this if your Miata has become a highway cruiser as much as a backroad driver. Having cruise control has certainly helped to make more car more comfortable.

Based on the cell concept, our employees are trained in on-line SPC practices. All products are final tested for specification verification. Rapid prototyping allows us to create new products per customer specifications at an incredibly fast pace with very little delay between product design and shipping. Our ability to scale production lines and add new products is largely due to our facility size. Our manufacturing plant measures over 80,000 square-feet. For years Rostra has been known throughout the automotive industry as a leader in the manufacture, as well as the development, of an extensive line of products.

When the cruise control has been determined to be operational within a strict set of parameters, it receives its sign-off from our staff and the control switch is permanently installed. Please note that I am handicapped in that I have no personal experience at all with the factory-installed Miata cruise control. Any reference that I make to the factory model is based on the description of that unit as it appears in the 1990 shop manual.

To find out if your vehicle has an RF switch available, check out our application guide. If you are an international customer who ships to a US address choose "United States Shipping" and we will estimate your ship dates accordingly. Once the unit is installed make sure that the cable attached to the accelerated is as tight as can be without opening the throttle. The project took a total of about 5 hours because we had trouble with the first mounting bracket. The bracket needed to be adapted to mount high enough to clear the washer tank and the intake manifold.

I drive to Oregon a couple of time a year (900+ miles each way) and the thought of this drive without the cruise is just painful.

When one is looking to set their cruise control with a single touch of a button, it should come as no surprise that people turn to Rostra Precision Controls as the brand to make such a task possible. Rostra's Precision Control's Universal Cruise Control System has been making waves in the cruise control market for quite some time and there's plenty of reasons why. Whether it be maintaining speed or accelerating, the Universal Cruise Control System makes it all possible without touching a pedal. So considering these perks, we're going to elaborate as to why Rostra's product is incredibly favorable for those to make short commutes or long drives across the country. Rostra Precision Controls has been building precision parts for nearly 150 years and has built a reputation as a supplier of cruise control systems, parking assist sensors,...

To acquire both vehicle speed signal (VSS), brake wire, and tachometer wiring colors and locations, please use our VSS Search above. If you do not see your vehicle listed, please download Rostra forms Form #4428 (for vehicles built between 1996 and 2009) or Form #4429 (for vehicles built between 1986 and 1995). We begin cruise control development by recording data from the vehicle's CAN bus using special software to determine which signals need to be sent to the ECU to control speed.

The servo module is supposed to be mounted on the engine firewall immediately under and to the left of the windshield washer fluid reservoir. However, the very much larger reservoir on Canadian models such as mine made this impossible, and the servo ended up immediately behind the air flow meter. It fits in quite nicely there, though it may make a planned future installation of a Jackson Racing cold-air induction unit difficult if not impossible. Considering the information above, a cruise control system might be exactly what you need for a safe and relaxing trip to your next destination. Thankfully, Mobile Installation Service is here to not only help you find the Rostra product you're looking for, but help you install it as well. Contact Mobile Installation Services today for a safer drive tomorrow.

Today, as a result of years of experience and research, we are continuing to lead the way with the development of new, innovative solutions to meet the challenges of tomorrow. Once the loaded software package has been verified in triplicate, we then test drive the vehicle to confirm that cruising speed holds between 31 and 80 MPH with minimal fluctuation. Both units come with an identical stalk-mounted control switch which fits very nicely on the lower steering column shroud.

This is no big deal, and is probably a result of the third party speed sensor being a very tight fit on the speedometer cable as it passes through the instrument cluster. The speed sensor is just barely touching the edge of the instrument cluster panel. The factory sensor is supposed to be smaller in diameter and supposedly does not have this problem.

Both are made by Rostra Precision Controls Inc of Laurinburg, North Carolina. Like the factory unit, both use a servo assembly to control the throttle cable, with the servo activated by engine vacuum tapped from a fitting on the top of the intake manifold designed for this purpose. We are currently pioneering the development and marketing of innovative automotive accessories. Backed by nearly 150 years of experience in precision manufacturing, we have earned our reputation as an ideal partner throughout the automotive industry. Whether you’re looking for a new Rostra complete cruise control kit or a replacement for an existing Rostra product, we have what you need to optimize your vehicle’s cruise control system. Take a look at all of our Rostra cruise control kits and more below and contact us if you would like any additional information about these products, or would like assistance with the ordering process.

The E-Cruise Module is the proverbial "brain" of the entire system and with the assistance of the included accelerator pedal interface harness, intercepts the communication between the pedal position sensor and the vehicle' Electronic Control Unit (ECU). Through the use of the included OBD port connector, the E-Cruise Module constantly monitors vehicle speed and loading and instructs the ECU to open or close the electronic throttle actuator to hold a set speed. Rostra is known as one of the most reputable brands in the cruise control market, with some of the best products available. M&R Electronics carries many different Rostra products, including Rostra complete cruise control kits and OEM switches. Regardless of your vehicle’s make or model, we likely have a Rostra cruise control product that’s perfect for your car or truck.

It surged violently at speeds under 50 mph and over mph. In the speed range where it did work, you always got the uneasy sensation of slight surging, with the feeling that the unit was being constantly activated/deactivated to maintain speed. Aside from that, it had a annoying tendency to stop working completely after a few minutes, meaning that the car would start losing speed. The resume/accel function never worked worth a damn. Our innovative Design and Engineering Department works with virtually all phases of the manufacturing process, right up through customer technical support. This hands-on approach allows us to respond to the changing demands of the marketplace.

Other than that, the instructions were comprehensive and simple to follow. I purchased this product from Performance Buyers Club to guarantee that I was buying the right product. I learned this from those who posted their reviews before me. Our manufacturing facility is organized to ensure flexibility, versatility, and the ability to respond quickly to market changes.

All of our Rostra cruise control parts are built to last and give you what you need for a reliable system. For safety's sake, please remember that a universal electronic cruise control systems cannot provide the same level of safety and convenience that a custom-designed cruise control system can. Save fuel and enjoy a relaxed highway ride with Rostra Cruise Control kits. Many kits feature great standard functions such as set speed, coast, reduce speed, resume, and accel with a one mile-per-hour tap-up or tap-down feature. These kits are available for a variety of different applications including standard mechanical throttle vehicles as well as drive-by-wire throttle vehicles. There are two after market cruise controls that I know of that are supposedly designed specifically for the Miata.

All of the Rostra products in our inventory are designed to last. Located below this FAQ section, you will find installation manuals for each product Rostra manufacturers including aftermarket cruise controls, backup camera systems, ultrasonic parking assist systems, seat heaters, and automotive lumbar support. We do not recommend using any Rostra cruise control systems on motorcycle, ATV, or other non-automotive applications as we do not validate the operation of these units on these vehicles. Due to safety concerns surrounding these installations, Rostra representatives are unable to provide technical support on these applications. Depending on your specific needs, we have the right Rostra cruise control kit for your vehicle. Our kits feature various switch models that are compatible with many different vehicle makes and models, along with cables and other parts needed to install a complete new or replacement cruise control system.

It's also worth mentioning that Rostra's systems are manufactured in the United States by the same company that had pioneered the development of such technology. The LED is a surface-mount light on the circuit board to the left of switch number ONE of the programming switches.

The control falls readily to hand, as the saying goes. We then need to determine which E-Cruise Module best suites a particular application based on the signal that we need to send to the ECU when cruise control is active. Someone referred to this unit in an earlier posting as the ‘single piece' control. It costs $US 140 from Moss Motors, shipping charges and the accursed Canadian GST not included.

In addition to the brake de-activation, this unit requires a connection to the Miata's clutch switch. All Miatae, whether cruise control equipped or not, supposedly come with one, and there is supposed to be a terminal (‘RSW') on the back of instrument cluster bezel which provides the output of the speed sensor. Possibly this is the case on US models, but my early 1990 Canadian had no such sensor, and I had to purchase a third-party one, the Mazda unit not being available as a separate unit, in Canada anyhow.

I look forward to my first long drive in this wonderful car. I would definitely do this again if I ever bought another Miata without cruise control. Since installation of the cruise control, my speedometer needle vibrates slightly.

If you are an international customer and would like to change the currency that prices are displayed in, you can do so here. Please note that Checkout Prices will be in US Dollars. If at all possible, buy a Miata with the factory installed cruise control.

Unfortunately, my understanding is that you have to buy the speedometer to get the factory sensor - it is not available separately. The ‘single piece' refers to the huge (7"x6") servo module which mounts on the driver's side fenderwell to the immediate right of the air flow meter, taking up almost all available space and just barely fitting in with my Flying Miata strut brace. Electrical controls (the ‘regulator') are on a small box attached to the servo.

I had written the control off as a useless piece of junk. I was seriously considering removing it entirely, when I heard about - and promptly ordered - the ‘two piece' Rostra model. Our product validation facilities allow us to simulate extreme real-world conditions including tests for hot and cold temperatures, along with ingress protection (IP). At our Orlando, FL facility, Rostra currently maintains a staff of over 100 employees between our manufacturing and business development teams.

Both units require connections to be made for electrical power and brake switch de-activation. Our sophisticated Prototype Department has an expert staff, working with today's most advanced equipment. They can bring a product from concept into full reality in astonishingly little time. This update adds the ability to select Blind Spot Cameras when moving as well as addresses a bug when the rear camera power was wired incorrectly. Once a vehicle-specific software package has been created, it is then written to the E-Cruise Module inside of a Faraday cage in order to reduce incidences of outside EMI. The latest in commercial fleet safety technology, this system detects blind spot, overtaking, and cross traffic of other vehicles, people, or objects.

Once I tightened it as much as possible without opening the throttle, the cruise has worked wonderfully. If you do have to get an after-market cruise control, make sure that you are getting the two-piece Rostra/MAX-5 unit. I don't know if it is available from anyone except Performance Buyers Club.
