CANTCU - TCU Bench Flash Service

Trouble Communicating with Your TCU via CANTCU?

If your Transmission Control Unit (TCU) isn't communicating with CANTCU, the issue may be related to software compatibility.

Depending on the transmission model, either an immobilizer reset or a custom software flash is usually required.

Some non-BMW transmissions require an initial bench flash to convert them to compatible BMW-based software. This process demands specialized and expensive equipment to read/write to the TCU.

Let us handle it for you! Ship us your TCU and we’ll perform the bench flash in-house — saving you time, hassle, and cost.

• BMW 8HP E-Series – 8HP45 / 8HP70 (E70, E84)
