Title: Simos18 torque reduction problem - VW GOLF VII GTI 2.0 TSI Stage 3
Post by: Micki on January 22, 2020, 11:17:45 AM
Hello,

I calibrate the VW GOLF VII GTI PERFORMANCE 2.0 TSI with SIMOS 18.1 ECU.
We reach good results with 435hp and 550Nm with safety EGT. On a dynamometer, everything works.
During our first road tests, we noticed the problem during the gear shift. (manual gearbox)

When we make an aggressive shift from 2 to 3 or from 3 to 4 we some times have a big torque reduction.
Reduction took around 8 seconds, and the engine move "torque limitation" linear and smoothly from around 180nm to 480 target at the time.
The proper torque is setup to 480-490nm and when everything works stay const on this level.

As an attachment, I provide logs from this attempt(from 14 sec to 22 - it is WOT), my original and modified file for the community.
Maybe it will be useful for someone. :)

Best regards
