Fair points. I hope government taxes will still allow widespread petrol powered cars in 20 years time!

Yeah, I think that is the big worry.


I think the percentage of older cars will mean it is no longer and issue emissions wise, as you say though tax might be, oh and the price of fuelling them.

Oh, and of course whether people will smile and wave as you drive passed or throw things at you and call you names.

You need to be testing out that MDM setting now as well wink
I gave it another squirt today, WOT from a r/bout. Back end moving slightly, TC blinking a bit. Properly fast little things! Imho certainly right now all this remap to 500hp seems a tad OTT.

410 is plenty, more power actually hurts it in my experience. It could perhaps do with a bump up to M4 power levels to restore the top end they took away and thats it.

I've hear that you can lean on the MDM quite a bit if you say, find yourself accidentally accelerating too hard out of junction in the countryside. Witchcraft apparently.

This is my default mode but I access it through the traction button (short press) as it keeps the more progressive throttle map but gives me all the noise. I am sure this can be programmed on a M2C and/or accessed via one of the mode buttons (or perhaps the M2C still has the traction button?).

Yes you can assign MDM to an M button.

There’s no exhaust control in the M2C, but as you say, MDM unlocks it fully (more than just switching the engine mode up)

I’ve never tried mine with mdm - don’t quite understand what it does.

That said, perhaps now is not the time, with slightly damp roads and super sports that are getting a little low, to find out....

I don't have a M button I only have a OG M2 laugh

What I am trying to say is that a soft throttle works really well with MDM and that conveniently, my traction button invokes MDM with the soft throttle map and full noise, so in effect I have a M button which is not configurable but happens to give me my default set up.

It turns traction control off and relaxes stability control up to a (modest) point, beyond which it reinstates traction control and stability control.

In other words you can do silly little slides and still have a safety net. If you stay beyond the (modest) yaw limits of MDM you're basically driving without support.

It relaxes the TC and allows more slip angle before reigning you in. It doesn't suddenly just STOP you from sliding like a traditional TC that design to prevent an accident. It just seems to very progressively control the amount it'll let you slide. It essentially lets you play at being Chris Harris but without the skill. Which is a problem in itself as it could lead to false sense of security.

I don't tend to use it when driving as I'm not one for sliding around on public roads, but it is fun for the odd cheeky Magnum PI moment.

Worn tyres and damp roads seem like the perfect combination to try it out at slow speed wink.

Thanks for the explanation (and Nick).
I assume on the comp it doesn’t make any difference to the engine or exhaust?
Quite ashamed that having had the car for 15 months I haven’t tried or even read up on it. laugh

In my defence, I didn’t expect to have it longer than 6 months.

Might have a little go to tomorrow during a necessary journey....

Switching up the engine to sport plus adds pops & bangs. MDM 'unlocks' the full exhaust. You have to press the t/c button twice to activate it, just to be sure. 'MDM' lights up on the left on the rev counter.

Have fun buying that milk... wink

I get plenty pops and bangs (too much for me sometimes) anyway as I’ve a Milltek EL fitted.

That milk may well be cheese by the time I get home if I’m not careful.

Are you sure?

Ive had my M2C for over 2 years, I get a louder exhaust with pops and bangs from pressing "sport plus" but nothing more in MDM besides lairy stability control.

I thought the same. Exhaust seems control by throttle map. Which for sport plus is ridiculous anyway. Seems to get toned down with DSC off though.

The engine sport plus does control the exhaust loudness as well as the mapping/throttle/overrun etc. It just doesn't open the exhaust all the way (although you now have me doubting myself!).

youtube on it (just on the M2 LCI not M2C): https://www.youtube.com/watch?v=CzKVFi0QvSc

ah, that'll be it. M2 + M2 comp quite different.

biggrin no I get that.

The guy in that video now has a M2C (I think his excellent miltek review was linked on a previous page). I'm sure he said the same about the M2C in one of his videos, I just couldn't be bothered to scroll through all of them to find it when the above one was to hand.

I tend to listen to exhaust clips late at night after a bottle of red (that's normal right confusedbiggrin), so I could well be mistaken.

So, in the user manual, there is a paragraph claiming the M2C recovers energy on the overrun... anyone know how this works?
Is it just a function of the alternator turning like any IC engined vehicle, or is there some electrickery going on with the diff?
