M-TRI lists separate BMW Stage 1 ECU, TCU tuning and EKPM3 fuel-pump control-module products. The catalog does not establish that these products form one required package or that every BMW engine, ECU, transmission or software version is supported. Check each offer separately and send your VIN before ordering. No single horsepower result or universal compatibility claim applies to every vehicle.
Which BMW ECU, TCU and fuel-pump products are listed?
The current BMW ECU & TCU tuning category links to separate offers. The product names below describe what the catalog lists; they are not a substitute for VIN-specific fitment or service confirmation.
| Catalog offer | What its listing identifies | Confirm before ordering |
|---|---|---|
| BMW Stage 1 ECU Tune (ZD8) – F/G Chassis Multi-Series | Stage 1 engine ECU tune; the product page offers chassis selections. | Supported engine, ECU hardware and software version, fuel and hardware requirements, exact calibration, delivery method and any vehicle-specific result. |
| BMW G-Platform TCU Performance Tune (ZD8) – Remote OBD Flash | A G-platform TCU offer; the title identifies remote OBD flash. | Supported VIN, transmission and TCU software, required equipment, process and whether the selected car needs any separate ECU work. |
| ZD8 BMW TCU Transmission Tune – 1/2/3/4/5 Series, X3 X4 X5 X6 | A separate ZD8 transmission-control tune listing. | Exact transmission and TCU version, supported VIN, included work, delivery requirements and how the offer differs from the G-platform TCU listing. |
| BMW EKPM3 Fuel Pump Control Module – Plug-and-Play (3/5/7/X) | A separate fuel-pump control-module product; “Plug-and-Play” appears in the product title. | Confirm that the physical module fits your vehicle, what is supplied, installation requirements and whether it is needed for the tune you are considering. |
What is the difference between an ECU tune and a TCU tune?
An engine control unit (ECU) manages engine operation. A transmission control unit (TCU) manages transmission operation. M-TRI lists ECU and TCU offers separately, so do not assume that one purchase includes both or that a TCU tune is required for every ECU tune. Ask which offer, if any, matches your vehicle and goals.
Does Stage 1 always raise a B58 from 382 to 420 horsepower?
No universal result is established by the current catalog. Power figures depend on the exact engine and vehicle, calibration, fuel, hardware, measurement method and test conditions. The earlier figures sometimes repeated in BMW tuning copy are not a verified promise for this product. Ask for a documented result for your vehicle and the conditions it assumes.
Is the EKPM3 module required with a Stage 1 tune?
The catalog presents the EKPM3 fuel-pump control module as a separate product. Its listing alone does not show that every Stage 1 ECU tune requires it. Ask M-TRI to confirm whether the module is needed for the exact engine, calibration and hardware in your vehicle.
What information should I send before ordering?
Send the full VIN, model year, model and engine, transmission, ECU and TCU identification or software version if available, country, fuel grade and current modifications. Ask for written confirmation of support, exact included work, required equipment, delivery and installation steps, expected results, price, restore procedure, support and warranty terms.
Frequently asked questions
Are the ECU, TCU and EKPM3 products sold as one bundle?
The catalog lists these as separate products. Do not assume they form a bundle or that all three are required. Confirm the exact package and price for your VIN with M-TRI.
Does every F- or G-chassis BMW qualify?
No universal fitment is stated here. Model, engine, ECU or TCU hardware, software version and selected offer all matter. Send your VIN and wait for written confirmation before ordering.
Is the Stage 1 tune performed remotely through OBD?
The ECU listing and TCU listings are separate offers with different product details. Confirm the actual delivery method and any required cable, computer, local installation or remote session for your selected product and vehicle.
Are the tune results, reversibility and warranty effects guaranteed?
This guide does not promise a power figure, restore procedure or warranty outcome. Ask M-TRI for vehicle-specific written terms and check the vehicle and local requirements that apply to you.
How do I compare the two TCU listings?
The category has a G-platform TCU offer and a separate ZD8 transmission-tune offer. Their names alone do not establish that scope or supported software is identical. Ask M-TRI to compare both against your VIN and transmission software.
