FAQ - SafetyPass Pro Big Rig Speed Governor Control System

How fast can we get the unit if we order it today? We live in the U.S. It usually takes 3 - 4 business days for U.S. delivery and 5-7 for Australia and other countries. We use USPS Priority mail and Express mail International. We ship within 24 hrs. on business days.

I have a IXS Cummins 550 horse non egr engine. What accessories would I need? You should have Metripack or Weatherpack connectors on your Cummins engine so the standard installation kit that comes with the control unit should be all you need... but, we have found that it is a good idea to visually inspect your speed sensor connectors that are located at the rear of the transmission on the output shaft because truck manufacturer's sometimes use alternate connectors that are not listed in the shop manuals in order to meet production quotas. The link below will show you where the speed sensors are located and allow you to compare your connectors with the ones shown here before ordering:http://www.fastertruck.com/connectors.html

What do I need for a 2008 Kenworth with a c-15 Cat and a Eaton 10speed? You should have Metripack connectors on your 2008 Kenworth with a Cat so the standard installation kit that comes with each control unit should be all you need... but, we have found that it is a good idea to visually inspect your speed sensor connectors that are located at the rear of the transmission on the output shaft because truck manufacturer's sometimes use alternate connectors that are not listed in the shop manuals in order to meet production quotas. The link below will show you where the speed sensors are located and allow you to compare your connectors with the ones shown here before ordering:http://www.fastertruck.com/connectors.html

I have a 2009 Freightliner Cascadia with a dd15. Is your device compatible with my engine? If you have a 2009 or 2011 Cummins, Detroit, the device will work. Be sure to check your speed sensor connectors and compare with the ones shown here: http://www.fastertruck.com/connectors.html

Will it work on a Mack? Currently, the device does not work on Mack engines however, it will work on Mack Trucks with different engines such as Cummins, Cat, Detroit, Volvo, Iveco, International, etc.

Does it work on Automatic Transmissions? Yes, but the control unit must only be activated when in high gear and never during the shifting process. The ones that worked had the speed sensor located on the tail shaft, just like standard transmissions and the connectors matched our installation kit. See connector and sensor locations here: http://www.fastertruck.com/connectors.html

Will this unit work on a DAF TRUCK, ITS GOT A 16 speed ZF manual gearbox? We have found that the device works on most trucks with exception to MACK truck engines only. We have recently tested an Iveco truck with a German ZF Automatic transmission and it worked good. You do have to splice because the connectors are different but it's only one wire.

I drive a Freightliner Argosy Cab-over with a CUMMINS SIGNATURE 520 HP AT 2000 RPM WITH A RTLO 20918 B GEARBOX AND MERITOR RT 46-160 DIFFS WITH 4.3 RATIO, will your installation kit fit my truck? Thanks for the inquiry. It is a good thing you asked because the Argosy cabover does require a longer installation cable than most trucks. In addition to the XM6KT you will also need a 6' (1.8m) Extension Cable, Item XM6EC6. This will extend the Main Cable length to 18' (5.5m) which will be more than adequate for your vehicle. All items may be ordered from our catalog. Just use this link: http://www.fastertruck.com/catalog.html When you get these two items, XM6KT and XM6EC6, you should have everything you need for a professional installation on your Argosy.

It is a good idea to check your existing connectors to insure a good match with our installation kit cables. Just use this link and compare with the connectors to your speed sensor. http://www.fastertruck.com/connectors.html

If you have only ONE sensor or one set of sensor leads (2-wires)then you're good to go with the items mentioned above. If there are two speed sensors or 2 sets of leads (4-wires) then you may need one of these items, XM6WY or XM6MY, depending on connector type. These are Y adapter cables (Catalog) and they keep the odometer mileage and ECM mileage in-sinc, so they always confirm each other and always read the same.

Will the truck computer or Qual Comm be able to tell how fast I'm driving? No. When the device is activated the truck computer or engine control module (ECM) will show and record speed data as shown on the speedometer which is controlled by the driver regardless of actual road speed. The device has the same effect on Qualcomm. You won't hear an "over-speed" beep when the unit is activated and only "driver controlled" speed data will be transmitted, not actual road speed.

Can I remove the device before I take the truck in for service? How long does it take? You can remove the control unit only. It takes about 10 seconds. You can also remove the entire setup, including the installation harness, this takes 3 to 5 minutes. After removal the vehicle returns to "pre-installation" status, complete with computer speed limitation.

What's the best way to route wiring on permanent installations? The best way to route the cables is to strap them to the existing wiring harness bundle. You will receive cable ties with your kit. Follow the existing wire bundle right along to the cab interior and use a cable tie every 1 foot (.3m) or so. There is usually an extra vacant hole in the firewall to provide entry to the cab interior or you can squeeze in along side the existing harness. After cable installation, spray WD-40 on underside cables to achieve a more natural look. Within a week or two, not even the installer will be able tell which cable is which or that anything has been changed. If you really want to get crazy, then you can douse the entire top of the transmission and wire bundles with diesel fuel... This is a serious deterrent to prying eyes and not that unusual because if you have ever had a fuel line leak on the engine, as I have, then you will know that the entire transmission can be saturated very quickly.

At what point of the order process do we identify the connector types? Connectors should be identified before you place your order. Use this link to see what connectors you must have on your vehicle to match our installation kit and where they are located.http://www.fastertruck.com/connectors.html Having the right connectors makes hook-up a snap.

How do I get the device to work on Eaton Auto-Shift? Here are Special Operating Instructions that will allow the device to work on the Auto-shift and other automatic transmissions:

1. Pre-set the device just below governed road speed. eg; If speed governor is set at 100kph (62mph) then set device speed at 98kph (61mph). Once the device has been Preset, no further adjustment will be required. Turn off the unit.

2. Drive up to your governed road speed with the device OFF. Allow time for your vehicle to stabilize at top speed.

3. Turn on the device and quickly hit Manual Mode on the tranny. Maintain current speed (governed speed) until manual mode is locked in, 5 or 10 seconds should do it.

4. Hopefully, no error codes will appear and you can try to gain speed by pressing on the throttle pedal. Allow the vehicle to stabilize for 30 seconds at higher ground speeds, only a few kph at a time. If it throws a code at a certain speed then stay below this speed and see what happens.

Will my Cruise Control still work if I have the device hooked up and turned on? When the device is in use, the cruise control will no longer function relative to speed, but can only be used to apply full throttle, or not. Sometimes this can be a handy feature when you are climbing a long, steep grade with a heavy load and your speed falls below 30-35mph where your cruise would normally cut-out. The device will allow full throttle cruise all the way down to 1mph, and that's cool but not much good for long-haul on the freeway unless you need to keep the truck floored, then it works great. Sorry about that, but it's a glitch we have to live with in exchange for the increased safety benefits and other money saving advantages the device provides.

Hello, I would like to know if you have a technique or something to increase the rpm? I would want that the rpm rise has 2300 instead of 2100, but it is blocked by the ecm. There are 2 governors on your vehicle; one is for road speed, the other is for engine RPM. Our device controls only the road speed governor. We do not have anything that will increase the engine RPM beyond the programmed maximum, Sorry.

Will this work on a Volvo Truck with a Volvo engine? Yes, it will.

Will this device allow a truck to also idle instead of shut down every 5 minutes or so? In most cases the device will allow the truck to idle forever. Also, the idle time is actually recorded by the truck computer as running time (driving time). This keeps the actual idle time that is recorded by the vehicle computer very low.
