I'm looking to get an ECM and send it to HP tuners in preparation for a Whipple Supercharger upgrade to save myself and the person doing the work some time.
My question is what number am I looking for?
The HP Tuners site mentions this information..
Note: Only 2019-2021 E90 ECMs are currently accepted. These include 2019 ? 2021 Serv# 12690388, 12703685, 12711852
In looking up those numbers, each one comes back to something different, so I'm unsure which one I should be ordering. Pulling back the wheel well covering and snapping a pic of my own ECM. I don't see any numbers that match what's given on the site.
Any assistance is appreciated.
