MEM-cal with S4s Code

Item #89661-17073
Price: Call for Price
Status: Limited Availability


-->

This is the replacement MEM-cal with the 1995 S4s code pre-installed. You can keep your original and have this one as a spare.

Benefits include smoother idle, 1.0 bar boost, and better low-end driveability.

Feel free to contact us about custom programming. We are able to change almost any parameter that you would like, except the rev limit. Idle speeds, fan switches, and the entire fuel/ignition map can be customized.
