- This is not a physical/shipped product. This upgrade requires you to send us your ECU for re-programming. You will be emailed a download link with detailed instructions after adding this to your cart and checking out.
- DME/ECU upgrades are available for all 993 Carrera models, but you must specify which style of DME/ECU your vehicle requires.
- Early model 993's (1994-1995) typically use a DME software chip, while the later cars (1996-1998) use an ECU software tune.
- Cars equipped with the "drive-block" feature (any model years) use an OTP-style ECU. You can verify that your car requires an OTP by inspecting the stickers on your factory ECU. If the number on the Porsche sticker is 99361866600, 99361866601, 99361866602, or 99361866603, then you will need to select the OTP ECU tuning option.
Shipping Details:Shipping costs for sending an ECU to Fabspeed is the responsibility of the purchaser. The ECU will be tuned within 24-48 hours of receiving it and Fabspeed will then ship back the ECU using whatever method it was shipped in with. (For example: If you send in your ECU via Ground shipping, we will ship it back via Ground. If you ship it via Overnight, we will ship it back via Overnight.)
