Elise R ECU Re-map
Discussion
On this subject is the cam change any different, ie. smoother (which is what I have heard) or is it just as abrupt? I know everyone bleats on about how good it is but does it make a huge difference to the car below 5500 rpm or is it exactly the same but with a lower cam change point?

Didn't particularly find it abrupt as is when I was out the other day testing the 111R I've got a deposit on.
In mine it feels like a turbo with "extended" lag... great fun but might be nicer if it came in gradually from 5500. Not quite sure how that could be achieved though.21TonyK said:

On mine when it changes over at ~6000 there is a big kick and then you feel the power get even bigger. I think at 6000 the high lift cam is only just getting started so if it comes at 5500 I reckon that it would perhaps be a little "out of range" and therefore provide a good smoothing effect.I can't decide if I want to do it or not. The kick can be fun but other times you want something a bit smoother. The other fact is there is a bit of a dead spot for about 300rpm before the kick which gets annoying. At least I am conciously thinking "come on 2nd cam!" for a few split seconds.

Not heard of an 'official' Lotus reflash before - is it definately after 5,000? The ones I've heard of move the change down to about 5,750, not as far as 5,000. I like the push, but it is easy to drop off cam if the gear change isn't quite quick enough. £400 sounds a tad pricey for what is probably a simple procedure for them though

5750rpm from what I can gather. More details...http://www.bell-colvill.co.uk/LotusShop/Details.as...
various "trade-in" options available

I had it done on my Exige 6 months ago.
It is certianly worth it unless you are poverty stricken, but there is the rub: it is in effect the map that the car should have always had from the start.
Lotus should have made it a recall but made money on it instead.
The driveability is very significantly enhanced by dropping the change point by only 500 rpm, especially dropping into the crucial power range when changing gears where the old car could leave you stranded in the torque-hole at 5900 rpm. The car is faster in more situations than before if not faster in absolute terms.

Thanks for the info. Is the cam change more gradual or just as abrupt?It is certianly worth it unless you are poverty stricken, but there is the rub: it is in effect the map that the car should have always had from the start.

I've had the upgrade done on my S2 Exige. It certainly seems to blend the 2nd cam in better with less of a punch. I have heard good reports from those that have had it done & track their cars. This they say is due to the blending in of the second cam making the car far more drivable & stable when cornering etc. just at the point of the cam change.

£934.12 inc VAT? Are they having a bubble bath!!?? 
Thats to buy a new ecu outright. It is less to get your current ecu remapped - http://www.bell-colvill.co.uk/LotusShop/Details.as... or http://www.bell-colvill.co.uk/LotusShop/Details.as... depending on which ecu is currently fitted to your car. So £495 or £395 + vat.Muz_Wez said:

Thanks, that's the most important bit for me. 21TonyK said:

Of course all those who have had it done will tell you that it is: as if anyone would admit they have just spent north of £300 on a bag of spanners.
Good point. Although with it being pretty popular (i believe) you might expect one or two people to speak up if they were disappointed.Ive had it for ages and love it. Definitely makes much more of a difference than it sounds - basically you can change up at high revs and stay on cam, rather than watching the rev counter for 8 or 8.5k depending on which gear you were in. I think there is a small step in power around 4k which wasnt there before too.
