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 Title: Re: Simos18 torque reduction problem - VW GOLF VII GTI 2.0 TSI Stage 3 Post by: Micki on January 22, 2020, 11:20:15 AM Attachment I provide in the below message because in main topic I got forum errors. :(
