Pricing being finalized
This configuration's price is being confirmed — contact SDPI to order.
Komatsu and other re-branded off-road Cummins engines are covered too — send us your ESN and we'll confirm the right calibration.
Details
Custom tuning for heavy-duty Cummins power. Select your engine above — where more than one control-module generation applies, pick the CM code too and the price updates automatically. ISX engines are covered across all control modules at one flat price. Komatsu and other re-branded off-road Cummins engines use the same calibrations. Find the CM code on the ECM dataplate, or send us your engine serial number (ESN) with the year, make and model and we'll confirm compatibility before you order.
What we'll need from you
- ▸ VIN and ECM operating-system / calibration number
- ▸ Year, make, model, engine and transmission
- ▸ Current modifications and what you want out of the tune
- ▸ Stock/read file upload — required on most platforms (EZ Lynk orders usually don't need one)
After checkout you'll complete a guided questionnaire and secure upload tied to your order. See the tune revision policy.
