ECU Flashing

There are two different options for ECU and TCU flashing. The First is for people who want the option of an at home flasher, allowing you to flash the stock and modified tune whenever and however many times you want, with no limit. The second option is for those who plan only ever flash the tune only once and have no need to ever flash again.


Learn more about both options below.
At Home Flasher Only Flash Once

TCU Flashing

We are happy to announce that we are the first company to release a solution for you to easily flash your TCU from the comfort of your own home. You no longer have to send the TCU to us in the mail and be without your car while waiting for your TCU to be tuned and sent back to you. The TCU on these cars cannot be programmed over the OBD port by anyone at this time, but we are still able to program the TCU by plugging into it directly after removing it from the car. Please watch the videos below on how to remove it from the car and then how to program it with our TCU Tune.

Reliability

Enjoy Maximum power while retaining factory reliability on our Stage 1 and 2 Tunes!

Unmatched Value

Our ECU and TCU bundle is the same price or less than other companies want for just an ECU Tune alone

Send In your TCU

Sadly, at this time the 992 911s TCUs have to be mailed in to be tuned.
