I'm new here. Just have had 500E-92 couple of weeks now. Interested to defeat asr, and i read you discussion, and made plastic tape tweak to asr module last night.
But it was bit disapointment to me, as i was not able to make wheels fully spinning loose. I did acceleration with 1 gear in b position. I have also E/S switch for transmission, and it did start with 1 gear when fully floored in position D. Maybe there was slight slip, but not very noticeable. In corner of course some smoke developed, but once straigt again, grip came back.
How you 500E behave? I have 225/65/16 michelin sport pilot tires in original rims.
