McLaren ME17 ECM Service - Upgrade Only

Tune your 4.0L twin-turbo McLaren. The Bosch ME17.8.33 engine computer in these cars has to be upgraded before it can be tuned. This one-time HP Tuners send-in service upgrades your original ECM so you can read, edit, write and data log with VCM Suite, or deliver tunes remotely through the Tune Delivery Network.

This is a send-in service. Your ECM has to come out of the car and ship to HP Tuners, so the car will be down while it's away. Please read this whole page before ordering.

How it works

1. Confirm your car is covered and place your order. Have your VIN handy; HP Tuners requires it.
2. Our team emails you the order number and the HP Tuners shipping form.
3. Remove the ECM, pack it carefully with the completed form inside, and write the order number on the outside of the box.
4. Ship it to HP Tuners with any carrier. Shipping to HP Tuners is the customer's responsibility; the shipping charged at checkout covers the return trip.
5. HP Tuners upgrades the ECM and ships it back.
6. Reinstall it, license it with 30 Universal Credits, then read and clear codes in VCM Scanner and start tuning.

Wait for our email before you ship. Please don't send your ECM until you have the order number and shipping form.

Before you ship: important

• Send the original ECM from your car. Spare, donor or replacement ECMs are not accepted.
• The upgrade is designed to avoid immobilizer and other relearns when the ECM goes back into the same car, but HP Tuners can't rule out extra procedures. A dealer resync may be required; that is the owner's responsibility.
• This service is performed at the owner's risk. Normal wear and weathering from the ECM's location in the car is expected.
