Pricing being finalized
This configuration's price is being confirmed — contact SDPI to order.
The serial-number prefix decides the ECM harness — the same engine model comes in both 40-pin and 70-pin. Not sure? Pick the closest and note it at checkout; we confirm from your read file.
Details
Custom calibration for Caterpillar-powered on-highway trucks and equipment — built for your ECM, serial number and application, not a generic file. Improved throttle response, fueling and drivability tuned around how the truck or machine actually works. Delivered via WinFlash/SIS or as a bench/bin file depending on your ECM. After checkout you'll complete the guided questionnaire (ECM details, application, current setup, goals) and upload your read file where required.
