BMW 328d Tuning, Bench or Remote, Post-LCI (Facelift) Models (2016-2018)

What it is
This is a Stage 1 performance tune for the BMW 328d diesel, Post-LCI (facelift) models. Unlike the Pre-LCI Q-PRO+ OBD-flash tune, this delivery method requires either bench tuning (ECU sent to KermaTDI) or a remote tuning session over a Kerma-provided Enet cable.

Performance gains

• +50 whp, +70 wtq at the wheels (dyno-measured, not crank), described as approaching 350 lb-ft of wheeled torque
• Up to 10% MPG improvement on long-distance driving
• Instant turbo response, turbo lag is described as removed
• More power delivered in the mid and top RPM range, useful for passing and spirited driving
• Tuning is done with stock components, no supporting modifications required

Two delivery methods

• Bench tune: Send your ECU to KermaTDI's tuning department.
• Remote tuning session: Available via a Kerma-provided Enet cable. You'll need a Windows-based laptop; a loaner laptop may be available, call to check availability.

Requirements and limitations

• Requires the vehicle's stock emissions system to remain fully installed, described as not a flow bottleneck for this tune's performance
• Vehicle year/model, transmission type, and tuning option required at checkout

Fitment
2016-2018 BMW 328d, including xDrive (Post-LCI/facelift models only). 2014-2015 Pre-LCI models use a separate Q-PRO+ OBD-flash tune instead.

Common questions

Does this fit a 2015 328d? No, 2014-2015 are Pre-LCI (pre-facelift) models and use a separate OBD-flash Q-PRO+ tune, not this bench/remote product.

Do I have to ship my ECU in, or can this be done remotely? Either. You can send your ECU in for bench tuning, or do a remote tuning session over a Kerma-provided Enet cable if you have a Windows laptop (a loaner may be available).

Do I need to remove my emissions equipment for more power? No, this tune is designed to work with the stock emissions system intact, and KermaTDI states exhaust flow isn't a limiting factor for this tune's performance.

Does this work on xDrive (all-wheel drive) 328d models? Yes, xDrive is explicitly included in the fitment.
