Title: Tuning job $1,000 - MED17.5.2 Throttle Response curve change. Post by: proaudiohd on May 19, 2023, 12:39:08 PM I have an APR Tiguan with the MED 17.5.2
The throttle plate does not open immediately, it opens with a very specific ramp time of 1.2 seconds under all loads and RPM's. There is even a starting and ending radius to this ramp time. I believe VW coded this ‘grandma curve’ intentionally. Be it for emissions, “smooth” driving experience, protecting the drivetrain, I’m not sure, but it makes the vehicle a dog to drive. I want to hire someone for $1,000 (One of you, or someone you recommend) to get rid of this gentle curve in programming. I want the throttle to open as fast as the actuator will let it. Looks like as little as 400ms judging by the release time. Maybe even faster, I haven’t tested it by itself. Scope: 1. Walk me through on a screen share where this curve is coded and how it can be changed to 0. No slope, no delay. 2. Talk about consequences that have to be accounted for – adjusting other maps etc 3. Modify my file and send it back to me 4. Verify performance in-vehicle with logs 5.

Maybe there is a newer version or even a factory update. Anyway without file or at least a version number hard to say...
