New ECM Purchase
Short on time and need an upgraded E41 ECM ASAP? This option allows you to purchase a brand-new, fully upgraded E41 ECM instead of sending in your original controller for servicing. This is ideal for enthusiasts who want their vehicles up and running as quickly as possible.
Once you install the brand-new, already upgraded E41 ECM, you must follow these installation steps.
Everything you need to tune your GM E41 ECM (L5P) vehicle with HP Tuners:
