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

What It Is
A Stage 1 performance tune for the BMW 328d diesel, Post-LCI (facelift) models. Because these ECUs cannot be flashed over OBD the way Pre-LCI models can, this tune is delivered by bench tuning (you send in your ECU) or a remote session over a Kerma-provided Enet cable.

Performance Gains

• Roughly +70 lb-ft of torque at the wheels, dyno-measured, putting total wheel torque near 350 lb-ft
• About +50 whp at the wheels alongside the torque gain
• Turbo lag described as removed, with noticeably quicker throttle response
• More pull in the mid and top RPM range for passing and spirited driving
• Up to 10% MPG improvement on long highway trips
• Runs on fully stock hardware, no supporting modifications needed

Two Ways to Get Tuned

• Bench tune: Ship your ECU to KermaTDI's tuning department
• Remote session: Tune over a Kerma-provided Enet cable using your own Windows laptop (a loaner may be available, call to check)

Requirements

• Stock emissions system must stay fully installed. Exhaust flow is not a limiting factor for this tune's output
• Vehicle year/model, transmission type, and tuning option must be specified at checkout

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

FAQ

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 or remote product.

Do I have to ship my ECU in, or can this be done remotely?
Either. Send your ECU in for bench tuning, or run a remote session over a Kerma-provided Enet cable if you have a Windows laptop.

Do I need to remove my emissions equipment to get the power gain?
No. This tune is built to work with the stock emissions system intact, and exhaust flow isn't what limits output here.

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

What's the difference between this and KermaTDI's other 328d tuning listing?
This is the bench or remote tune for Post-LCI 2016-2018 cars. Pre-LCI 2014-2015 cars use the separate Q-PRO+ OBD-flash product instead, since they tune differently.
