I've heard a few people talking about these recently and I'm a bit confused. How does a full throttle upshift in a 3 pedal manual work? Do you keep the throttle pinned (I'm assuming so) push the clutch and slip the next gear home and then...? What happens next? Its not possible to engage the next gear without the engine speed dropping (unless the car has sufficient power to instantly spin the wheels to match the engine speed)?

 

It all sounds a bit harsh on the transmission to me? How do these fancy ECU's match the transmission and engine speeds without putting undue stress on the gearbox and shafts etc? Also how much of an performance advantage is gained from such a system?

 

I know there are a few semi-auto & SMG 'boxes on the market that can do this now - my mates M3 has the SMG - but it seems brutal as hell between 1st and 2nd. The thing is, they were developed from the outset with this in mind, whereas with a Zed you're asking a high tech question from a relatively low tech device?

 

I'm sure I've missed the point somewhere..

keep throttle pinned, depress clutch which throws a switch and engine revs drop to 4500 via EMS (lot's of backfiring) foot off clutch back to full throttle :)

Thanks bob, I was hoping you would see this!

 

Is 4500 the perfect speed for each ratio, or could you tune it to whatever revs you wanted in any particular gear?

 

Do you find it brutal, or does it actually make it a sweeter change?

lol well I haven't used it yet because Dan fitted a switch that I don't like. You can set it up for whatever you like but 4500 is good for the zed I think. The gear changes would be better and of course the main reason is that you don't lose boost during changes :) When I get the right switch fitted then I'll let you know. By the way mine is run by my AEM.
