This DME (engine computer) software upgrade is for:
BMW E53 (X5 4.4L), engine M62B44TU
BMW E53 (X5 4.6L), engine M62B46TU
BMW E38 (740i/iL), engine M62B44TU
BMW E39 (540i/iA), engine M62B44TU
Other BMW models with a M62B44TU conversions/swaps.
The DME will have to be sent to us in order for the DME to be updated with performance software. If you're a local in the Seattle area in Washington, you're welcome to stop by and I can do this in person without having to remove the DME from the vehicle.
Removal of the DME is very simple, on almost all models the DME is located in the black electronics box near the firewall on the passenger side under the hood. If you have any concerns or questions, feel free to send me a message.
Please print out this form and mail it in with your DME. DME will not be flashed until the form is filled out and sent to us. Thank you.
