Cummins ECM ID Lookup: What the 3-Letter Code Means (BGT, BDR, BBN…)

Every Cummins ECM carries a three-letter product code — BGT, BDR, BBN — and once you can read it, you know which engine platform you are working on before you even open the calibration. Cummins calls it the Product ID; most technicians just call it the ECM ID. This page is a full lookup table, plus three quick ways to use it right here on VietDiesel.

What is a Cummins ECM ID?

The ECM ID is a three-letter code Cummins assigns to each engine + control module platform. It tells you two things in one glance: the engine family and the ECM generation. BGT is an X15 on a CM2350 module; BBN is an ISB6.7 on a CM2250; BDR is an ISX15/ISX11.9 on a CM2350. One code can cover several ratings and model years, but it always pins down the platform — which is exactly what matters when you are matching a calibration or one of our services to your engine.

It is not the same thing as the ECM part number printed on the module housing — that one identifies the hardware box. If part numbers are what you are holding, see Cummins ECM part numbers explained.

Where to find your ECM ID

• Calterm or INSITE — the product code appears on the connection screen as soon as the tool talks to the ECM.
• The calibration file name — Cummins cal files usually start with it: a file named BGU_22.60.70.02_… is a B6.7 CM2350 calibration.
• The ECM dataplate — the ECM code on the engine dataplate belongs to the same platform. If the dataplate is all you have, that is enough: send us a photo and we will identify it. Related guide: how to find your ESN, VIN and ECM code.

Three ways to look up a code on VietDiesel

1. Type it into site search — the search engine on this site understands ECM IDs. Type BGT and it automatically matches our X15 / CM2350 services, even where the code itself is not printed on the page.
2. Ask the live chat — the assistant in the corner of this site carries the complete reference, including the newest codes. Paste your code and ask what engine it is.
3. Use this page — press Ctrl+F (Cmd+F on a Mac) and type your code.

Newer codes (2017 and later)

Cummins keeps issuing new product IDs, and the newest generations — X15 Performance and Efficiency Series, the 2021+ B6.7 and L9, and others — are not in the public reference tables yet. The following codes are valid current-generation Cummins ECM IDs:

BFI, BFN, BJU, BJX, BKB, BKC, BKD, BKF, BKG, BKH, BKL, BKN, BKP, BKS, BKT, BKU, BKV, BKX, BKY, BKZ, BLE, BLH, BLI, BLL, BLM, BLN, BLR, BLU, BLV, BLY, BMA, BMB, BMD, BME, BMG, BMH, BMI, BMJ, BMK, BML, BMM, BMN, BMO, BMU, BMY, BMZ, BNA, BNB, BNC, BND, BNE, BNI, BNJ, BNK, BNM, BNO, BNP, BNQ, BNR, BNT, BNU, BNV, BNW, BNZ, BOA, BOC, BOD, BOE, BOF, BOI, BOJ, BOP, BOR, BOS, BOU, BOW, BOX, BOY, BOZ, BPA, BPB, BPC, BPD, BPE, BPG, BPI, BPJ, BPK, BPL, BPM, BPN, BPO, BPP, BPQ, BPR, BPS, BPT, BPU, BPV, BPX, BPY, BPZ, BQA, BQB, BQC, BQD, BQE, BQF, BQG, BQI, BQK, BQL, BQM, BQN, BQO, BQP, BQQ, BQR, BQS, BQU, BQW, BQX, BRC, BRD, BRF, BRG, BRH, BRI, BRJ, BRK, BRM, BRN, BRO, BRR, BRS, BRV, BSA, BSB, BSC, BSD, BSE, BSF, BSG, BSH, BSI, BSK, BSL, BSM, BSN, BSR, BSS, BST, BSU, BSV, BSX, BSY, BTA, BTC, BTD, BTE, BTG, BTH, BTI, BTJ, BTK, BTL, BTM, BTN, BTO, BTP, BTQ, BTR, BTS, BTT, BTU, BTV, BTW, BTX, BTY, BTZ, BUA, BUB, BUC, BUE, BUF, BUH, BUI, BUK, BUL, BUO, BUP, BUQ, BUU, BUV, BUX, BUZ, BVA, BVB, BVD, CSR, K27, K29, K40, K41, K42, K43, K44, K45, L51, L52, L53, L54, L55, L56, L57, M51, M52, M53, M54, M55, M56, M57, TST

Have one of these? The live chat on this site already knows they are current-generation codes. To identify the exact engine and see what we can do with it, send a photo of the ECM dataplate through the contact page — we will identify it and reply with options and pricing.

Can I calculate the ECM ID from my ESN or VIN?

No — there is no formula. Which ECM code an engine left the factory with is a database record, not something encoded inside the serial number. Two consecutive ESNs can carry different codes. A VIN can narrow down the engine model, but never the ECM code. The reliable path is always the same: read it in Calterm/INSITE, read the calibration file name, or photograph the dataplate and let us look it up.

Check what we can do for your engine

Once you know your code, search it — every tuning and calibration service we offer for that platform will be listed with pricing. If nothing shows up, or you are not sure what you are looking at, the chat and the contact page are the fast lanes: dataplate photo in, answer out.
