    Hello, after nearly a decade in the business and a million miles I've decided it's time to buy my own truck.

    I've pretty well decided on freightliner but I have a few concerns. I initially was attracted to a glider kit with a ELD exempt D60 engine and a 13sp. But after researching some lease carriers I find that many of them require tractors that meet the ELD mandate. Which for the most part is fine I'd like to run e-logs but that means I can't run a pre emissions detroit engine. I know the newer DD15 gets great mileage but I worry about longevity and reliability as I'll be buying used. So my question is what is my best option for an engine that is ELD compliant whilst doing my best to avoid all the emissions crap. I suppose I can live with a EGR but want to avoid DEF altogether. Thanks.

    Why can’t you run a eld on a pre emissions truck?
    I know many that do.
    12.7 Detroit 2000 and later is plug and play, earlier models require a power wire because power is cut to the port with key off.

    You can run an ELD most any electronic engine. We have a 99 379 pete in our fleet with a 1LW cat and there is an omnitracs ELD unit on it. So I’d say find your truck with the S60 and go truckin.

    Thanks for the reply. I had wondered about that because they do say 99 and older are the exempt ones. Had considered the newer 14L ones as well but heard they weren't quite as reliable as a 12.7.

    Thanks. Sounds like there's hope to find what I'm looking for after all. I've seen dd15 cascadias auctioning cheap but a reluctant to buy anything new with all the emissions and electronics. Will be my own mechanic for the most part.

    Run a 95 379 with a S60 Detroit now - DDECIII, with Qualcomm Omnitracks ELD.

    Find that old puppy and get to work.
     
    Speed_Drums Thanks this.

    The exemption just means that you can be exempt from the ELD and run a paper log if you choose.

    But you can run the eld if you like.

    That 12.7 engine is really a good one.
     
    Speed_Drums Thanks this.

    I had a 2000 Volvo with 1999 S60 Detroit and it could run the Omntracks. It was probably AOBRD. Not sure if it could run a full ELD today but it probably could become most of that was just software update to Omntracks system. That Volvo had the data port plug by the dash. So it was just plug it in and go.

    Thanks for all the replies. What version of DDEC is required to run say a modern omnitracs / qualcomm eld system?

    Appendix A to Subpart B of Part 395 - Functional Specifications for All Electronic Logging Devices (ELDs)

    Technical specifications: 49 CFR Appendix A to Subpart B of Part 395 - Functional Specifications for All Electronic Logging Devices (ELDs)

    4.2. ELD-Vehicle Interface

    (a) An ELD must be integrally synchronized with the engine of the CMV. Engine synchronization for purposes of ELD compliance means the monitoring of the vehicle's engine operation to automatically capture the engine's power status, vehicle's motion status, miles driven value, and engine hours value when the CMV's engine is powered.

    (b) An ELD used while operating a CMV that is a model year 2000 or later model year, as indicated by the vehicle identification number (VIN), that has an engine electronic control module (ECM) must establish a link to the engine ECM when the CMV's engine is powered and receive automatically the engine's power status, vehicle's motion status, miles driven value, and engine hours value through the serial or Control Area Network communication protocols supported by the engine ECM or the vehicle's databus. If the vehicle does not have an ECM, an ELD may use alternative sources to obtain or estimate these vehicle parameters with the listed accuracy requirements under section 4.3.1 of this appendix.​

    4.3.1.2. Vehicle Motion Status

    (a) An ELD must automatically determine whether a CMV is in motion or stopped by comparing the vehicle speed information with respect to a set speed threshold as follows:

    (1) Once the vehicle speed exceeds the set speed threshold, it must be considered in motion.

    (2) Once in motion, the vehicle must be considered in motion until its speed falls to 0 miles per hour and stays at 0 miles per hour for 3 consecutive seconds. Then, the vehicle will be considered stopped.

    (3) An ELD's set speed threshold for determination of the in-motion state for the purpose of this section must not be configurable to greater than 5 miles per hour.​

    (b) If an ELD is required to have a link to the vehicle's engine ECM, vehicle speed information must be acquired from the engine ECM or the vehicle's databus. Otherwise, vehicle speed information must be acquired using an independent source apart from the positioning services described under section 4.3.1.6 of this appendix and must be accurate within ±3 miles per hour of the CMV's true ground speed for purposes of determining the in-motion state for the CMV.​

    4.3.1.3. Vehicle Miles

    (a) An ELD must monitor vehicle miles as accumulated by a CMV over the course of an ignition power on cycle (accumulated vehicle miles) and over the course of CMV's operation (total vehicle miles). Vehicle miles information must use or must be converted to units of whole miles.

    (b) If the ELD is required to have a link to the vehicle's engine ECM as specified in section 4.2 of this appendix:

    (1) The ELD must monitor the odometer message broadcast on the engine ECM or the vehicle's databus and use it to log total vehicle miles information; and

    (2) The ELD must use the odometer message to determine accumulated vehicle miles since engine's last power on instance.​

    (c) If the ELD is not required to have a link to the vehicle's engine ECM as specified in section 4.2 of this appendix, the accumulated vehicle miles indication must be obtained or estimated from a source that is accurate to within ±10% of miles accumulated by the CMV over a 24-hour period as indicated on the vehicle's odometer display.​

    4.3.1.4. Engine Hours

    (a) An ELD must monitor engine hours of the CMV over the course of an ignition power on cycle (elapsed engine hours) and over the course of the total engine hours of the CMV's operation. Engine hours must use or must be converted to hours in intervals of a tenth of an hour.

    (b) If an ELD is required to have a link to the vehicle's engine ECM, the ELD must monitor the total engine hours message broadcast on the engine ECM or the vehicle's databus and use it to log total engine hours information. Otherwise, engine hours must be obtained or estimated from a source that monitors the ignition power of the CMV and must be accurate within ±0.1 hour of the engine's total operation within a given ignition power on cycle.​

    4.3.1.5. Date and Time

    (a) The ELD must obtain and record the date and time information automatically without allowing any external input or interference from a motor carrier, driver, or any other person.

    (b) The ELD time must be synchronized to Coordinated Universal Time (UCT) and the absolute deviation from UCT must not exceed 10 minutes at any point in time.​

    4.3.1.6. CMV Position

    (a) An ELD must determine automatically the position of the CMV in standard latitude/longitude coordinates with the accuracy and availability requirements of this section.

    (b) The ELD must obtain and record this information without allowing any external input or interference from a motor carrier, driver, or any other person.

    (c) CMV position measurement must be accurate to ±0.5 mile of absolute position of the CMV when an ELD measures a valid latitude/longitude coordinate value.

    (d) Position information must be obtained in or converted to standard signed latitude and longitude values and must be expressed as decimal degrees to hundreds of a degree precision (i.e., a decimal point and two decimal places).

    (e) Measurement accuracy combined with the reporting precision requirement implies that position reporting accuracy will be on the order of ±1mile of absolute position of the CMV during the course of a CMV's commercial operation.

    (f) During periods of a driver's indication of personal use of the CMV, the measurement reporting precision requirement is reduced to tenths of a degree (i.e., a decimal point and single decimal place) as further specified in section 4.7.3 of this appendix.

    (g) An ELD must be able to acquire a valid position measurement at least once every 5 miles of driving; however, the ELD records CMV location information only during ELD events as specified in section 4.5.1 of this appendix.​

    4.3.1.7. CMV VIN

    The vehicle identification number (VIN) for the power unit of a CMV must be automatically obtained and recorded if it is available on the vehicle databus.
