I have. Had a drive earlier in the week and switched it off with this thread in mind. I'm not convinced in the difference between VSA on/off. Didn't really think there was much difference. If there was, it was very marginal. Tried a few different acceleration scenarios and didn't think the car was any more responsive to the throttle movement with the VSA off.
I'm in the queue to try out the test ECU. Once it's with me, I'll give it a go and write a review.
