Adding a speed limiter to a fleet of trucks

Benjamin Diagnostician Murfreesboro, Tennessee Posted   Latest  

I was called by a customer that has a customer with a plumbing company with a fleet of trucks (mostly GM’s and some Fords). He is wanting to set up a max speed limiter on the fleet at 70MPH. I know newer Fords have the MyKey option and I could do that no problem if the trucks in the fleet have this option. I was wondering if there is any aftermarket software or equipment that may be able to do this such as abrites, etc.. Is It possible to set this with OE GM software? I don’t mind buying equipment if it would make this process easier since it sounds like the fleet is mixed GM and Ford. I am looking for advice on the best way to get this done. Thanks!

I would look into Hptuner, has an option where you can change the speed limit.

EFI Live is GM only but is another option. HP Tuners seems to like to tie tuning to 3 modules so you pay 3 tokens.

Thank you Michael for that info. I will look into them. I found out later today the entire fleet is GM’s So that may be a good option.

If they’re newer and possibly under warranty for GM you need to contact SPS and tell them you need a VCi for that. Once ready you will reprogram PCM and BCM. I have done quite a few for Fedex

Big Brother Stuff :O) [Automated alerts can actively reduce speeding and excessive idle time to immediately cut fuel costs. Actively monitoring driver behavior also discourages employee downtime and eliminates unauthorized use of vehicles, which dramatically effects unnecessary overtime.] advantrack​.​com/gps-tracking-s… Better yet, just install some fake tracker 'Black Boxes'…

Hi Benjamin: The GM LCF & 6500XL are programmable. You didn't say what you have though. When I worked on plumber's trucks, they were generally class 4. For all I know, your customers may be running overloaded class 2 or 3 units to save on registration fees. I suggest treading carefully and get documentation. I appreciate that the concern would normally be in raising the speed; e.g. older…

I work with fleet trucks on a daily basis. And on the fords you can either go the my key route or if you have access to ids the factory ford scan tool you can program the speed under programmable parameters. Then click 70mph and your done . Now as far as gm trucks your gonna have to pay 40 dollars per truck through ac delco tds . And you can get the new file and reflash the truck. And you will…

I I have an IDS and thought I remembered seeing that option under programmable parameters in the past. I also have an MDI2 and knew I could go the VCI route, but I hate having to make a phone call every time I need to do this. I am looking at the HPtuner mentioned above.

Andrew Hinojosa, I purchased the HP tuners setup and I must say I really like it so far. I actually was able to diagnose a truck that had the wrong PCM installed with it. I read the PCM and found the oxygen sensor setup was not correct for the vehicle. I would have never found this using any of my scan tools or even the factory tool. The owner had installed the PCM and it was setting O2 heater…
