1 | Tamper-proof EPA engine programming | Vehicle Speed Limiter (VSL) and Engine Idle Shutdown Timer (EIST) are Emission Controls that may be noted on the door label. The default VSL speed is 64 MPH and EIST requires 5 minute idle shutdown. The expiration distance for these parameters is between for 300,000 - 1,259,000 miles and CANNOT BE RESET during that period. The expiration is not noted anywhere on the vehicle. You must call Parts and get this number, and use an engine tool to remove the value when applicable, if desired. |
2 | Propane chassis | Most propane bottles have a RH side pump and thus requires a RH side PTO with a jackshaft to connect the two. |

CNG options to consider
Some tank suppliers could benefit from a custom frame drilling, (charged for each chassis). Locating A&E lines back 41 – 51” with cabinets is must. Brushless alternators are also required for safety. In the cab batteries with saddle tanks (horizontal frame/rail mount). Jump start terminals BOC/S, not under hood. With cabinets, don’t order slide bar for trailer connections. Lights on the BOC/S will be blocked if this is a cabinet installation, you might go with switch and wiring only. Don’t order a bunch of gauges if the body builder will add a Methane detector, which is not required with CNG, but is with LNG tanks. Reason, CNG has Mercaptan (smells), but LNG doesn’t (too cold). Make sure you arrange a PDI.
