urS4 w/MTM upgrade

greenspun.com : LUSENET : Chip upgrades for Motronic 20-valve 5-cylinders : One Thread

Well, I did it. The MTM chip upgrade for my '93 S4 just arrived from Anderson Motorsports. Good deal due to group purchase from S Cars website. The results are outstanding. The car always accelerated quickly but there seemed to be something missing. Too narrow of a power band and too susceptible to whether the turbo was spooled up. Quick ... But ... I can now say there is no "but" left in describing the acceleration. The power band is MUCH wider and flatter (as well as more power). More instantaneous too. No excuses, just true Audi type strong constant pull. I recommend it highly to anyone considering this option. Total agreement with Jimmy Pribble at http://www.urs4.com/UrS4_main.htm . This is also a good place to look when you want a description of how to remove the computer from under the passenger's floor board. My wife (who drives this car most of the time) says it is no longer quick but it's a rocket. She's mad at me for doing this because now she's going to have a hard time keeping it within the speed limit. Even 4th gear pulls solidly from 80 to 120. This is not to start a debate as to who's chip upgrade is better, only to say any good chip makes a big difference in how satisfying the car can be.
