Crenshaw Engineering
Power From the Tune, Not the Parts List.
Crenshaw Engineering specializes in ECU calibration and custom coding that extracts real, measurable gains — whether you're chasing street reliability or track-day performance.
Most aftermarket tuning is guesswork dressed up as engineering. Drivers invest in hardware upgrades but leave power on the table because their ECU calibration doesn't match. Crenshaw Engineering closes that gap with data-driven tuning.

FAQ
What vehicles do you work on?
We primarily work with European performance vehicles (BMW, Audi, Porsche, Mercedes). Contact us with your specific vehicle for availability.
Do I need to bring my car to you?
For dyno tuning and calibration, yes. For ECU coding and remote-flash tuning, we can sometimes work remotely depending on the vehicle and scope.
Will tuning void my warranty?
Modifications can affect warranty coverage. We'll discuss the implications for your specific vehicle and situation during consultation.
