The Details
This one-time service upgrades an original E90 ECM or E93 ECM (Global B generation only) and is required for tuning using HP Tuners’ software.
Users must physically remove their original ECM from their vehicle and ship it to HP Tuners’ headquarters for servicing. Once upgraded, users have full access to calibrate, log, and scan via the OBDII port.
Note: No IMMO relearn, crank relearn, or “Replace ECM” function in VCM Scanner is required as long as the ECM returns to the same vehicle it came from.

Note: Universal Credits for licensing are not included in the cost of any upgrade service or purchase. Credits must be purchased separately.
We ask for your VIN up front so the calibration is built for your exact car — not a generic file.
Before you order
Not sure this is the right file for your car? Ask first — we would rather talk you out of the wrong product than refund it.
Your factory file is archived
Going back to stock is always one flash away.
Built for your VIN
That is why we ask for it at checkout — the calibration is written for your exact engine and software version, not a generic map.
Support after the sale
Installation help by phone, and an engineer on the line for remote flashes.
