In less than two weeks I’ll be leaving for London, England to begin my participation in the Paris To Prague rally. In this rally I will be navigating for Michael Eatough in his 1966 Mercedes-Benz 230S. I will meet Michael at Heathrow Airport in London and then we’ll drive to Paris for the beginning of the rally. As an engineer who often works on tunnel projects, I look forward to crossing from England to France via the famous Channel Tunnel.
Michael Eatough’s 1966 Mercedes-Benz 230S
Michael’s Mercedes-Benz has been prepared with endurance rallies in mind. Many modifications and preparations have been made over the years with an emphasis on reliability and durability. This car has already successfully completed in several endurance rallies, including the Trans America Challenge in 2012 and 2015.
Because the car is already very well prepared for long distance rallies, I will be enjoying the benefit of not having to finish preparing the car just before the event. However, I will be bringing along a rally clock and some watches, just to augment the equipment already in the car.
At this time, the car is fitted with two very good rally computers as shown below. This two-rally-computer approach is an example of Michael’s approach to rally car preparation – strength and redundancy. The unit on the left in the photo is a Monit G-200 rally computer, while the unit on the right is an up-to-date GaugePilot rally computer with the “Rally” model set up. I understand that both units are fully functional in the car and they have even been calibrated by Nigel Cousins of GaugePilot. I also understand that the Monit rally computer has since been relocated to a location that is higher on the dash for better visability and is easier to reach while watching the road, reading the road book, and reading the rally computer data all at the same time.
Rally Computers Installed In Michael Eatough’s Mercedes-Benz
The Monit G-200 rally computer is the top-of-the-line of the Monit product line. The key feature of this rally computer is that it is driven by a GPS signal with a wheel sensor backup. The unit can be switched from being GPS driven to be wheel sensor driven by the pushing of a button.
Monit G-200 Rally Computer Displaying The Total And Incremental Distances
The Monit G-200 features include two distance counters, current and maximum speeds, a stopwatch, a time-of-day clock, average speed and fuel management system. The Monit G-200 is a compact unit, measuring 115mm x 56mm x 20mm, that can be easily added to most cars. However the compact nature of the Monit rally computer also limits the display capability of the Monit to two pieces of information. As a result, I will be bringing along my Brantz Rally Timer clock to position beside the Monit rally computer so that I can see the time while also looking at both the total and incremental distances on the Monit rally computer.
The other rally computer in the car is the impressive GaugePilot. There are many display screens available with the GaugePilot. At this time I believe that the two displays that will be of interest to me are the Twinmaster and the Rallymaster displays. The Twinmaster display is shown below.
GaugePilot’s Twinmaster Display
In general, the Twinmaster display replicates the information provided by a Halda Twinmaster odometer. It should be noted that a multi-capacity GaugePilot rally computer in the Rally model probably costs less than an original Halda Twinmaster currently costs. The Twinmaster display has two odometer displays – total distance and the incremental distance. In addition, a digital time-of-day display is provided on the same screen. This display provides the basic information to keep the car on course. The time-of-day clock makes the timing easier.
Changes and adjustments to the Twinmaster screen are made using the three knobs located across the bottom of the screen. Changes can be made by rotating the appropriate knob and activated by pushing the knob.
The other display that I am interested in is the Rallymaster screen as shown below.
GaugePilot Rallymaster Display
The Rallymaster display provides the same information as the Twinmaster display plus allows for the entry of a desired average speed and a visual needle display showing how close the car is moving with respect to the perfect time. The needle display is present when the car is within +/- 20 seconds from the perfect time.
There are several other displays available with the GaugePilot rally computer, but I am not going to allow myself to get overwhelmed by the tremendous capability of the GaugePilot rally computer the first time that I use it. I am going to initially focus on using these two very useful screens to their maximum capability, then expand to using the additional screens/displays as need and time dictate. These two screens will provide almost all of the information that I’ll need to do the navigation and timing in the Paris To Prague rally.
I am fortunate to be able to step into a reliable, tested car that is already fitted with such two fine rally computers as the Monit and the GaugePilot. Having the two independent operating and calibrated rally computers minimizes the potential for rally navigation equipment failures to have a devastating impact on our rally.
