Someone posted that they drive like that AGES ago on Mtorque/BM3W - Ninja it's not you is it? (Simon?)

Yep - it's me, Elliot.

I've only ever driven my car this way ever since I owned it. I probably gave a fairly short description of how to drive it like this.

Obviously you can't change gear at 100% open throttle from 1st to 2nd in traffic. I drive mine in S2 or S3 until it has warmed up. I only use my CSL as a toy now, so I rarely drive in any traffic to be honest.

I tend to change gear very early in the rev range (1500 rpm) or very late (above 6000 rpm) to stay out of the maximum torque band, as it appears to be the torque that causes the slurring.

I have said before that it sounds like complete madness to drive like this, but it is surprisingly easy ( not in traffic). Even if I'm just gently cruising down the road at 50 mph following a line of traffic and I want to change from 5th to 6th, I floor the throttle flick the paddle for 6th, as soon as the gear is fully engaged, lift off back to a balanced throttle - you only gain a couple of mph, give it a go. It just sounds odd when you read it here on a forum, but if you get in your car and try it, it's not a problem. You just have to programme yourself to get through the gears quickly - 40 mph in 6th gear isn't a problem. If anyone has really bad slurring, drop into S2 or S3, and perform 100% throttle changes at 1500 rpm, or even 1200 rpm if you can. The lower the revs, the better. Then build it back up to S4, and S5.

The whole issue of the clutch slur is not a mechanical one in my opinion, the actual cause is down to the software releasing the clutch too slowly. The computer only has 3 variables to take into account when orchestrating a gear change, road speed, throttle position (engine load), and revs. If you only have 10% throttle loading, then the clutch operation is going to be fairly gentle to give a smooth drive - I think this becomes absorbed into the self learning part of the software and manifests into slurring at full throttle, either as slow clutch release or re-loading the engine too soon. My car certainly feels as if there is a definate gap between engaging the gear and reinstating full load. Either way, my car has been mint ever since I drove it like this. If I had any computer skills I would video the way I drive and load it onto youtube....but I haven't the faintest idea - any takers?
