andymot, Do you have plots of the final result including the remap? I can only say I am so happy with my car. I can install my open filter system in ten minutes to have even more top end. But I love how it works with the standard air filter and it doesn't get on my nerves acoustically but sounds beautiful.
There was a guy on here called Adrian that was a guinea pig for MMC and there is a looong thread on here all about rev hang somewhere which would be well worth reading. Rev Hang He sold the car for an Aero shortly after the experiment.
Richard, you ruined my nice evening. I'm just kidding. Of course I read the whole thread, very interesting and very exciting (for a Morgan Enthusiast).
What's most unfortunate is that they worked hard to find solutions with the help of Adrian. But then suddenly the solution is no longer available. Worse still, they invent an excuse (cable connections not available). But in reality it was an emission problem (why the rev hang was obviously necessary).
It reminds me of my second Roadster, 3.0 S2 MY 2008, which also had this terrible rev hang. The car was only therefor cruising. Sporty driving was impossible. Then I got another ECU from my dealer at no cost. The car was totally transformed, incredibly good to drive. It was said that now all S2 would get the new ECU at no cost. What was the result: My Roadster was absolutely the only one who got this upgrade. At MMC they didn't know about it only a short time later.
Like you Heinz, if someone is about to purchase a new Morgan we owe it to them to provide a balanced view otherwise the forum is not functioning well although at times it will not cover the MMC back up system with glory it happens to be the truth on occasions. Rose tinted spectacles don't suit me

This plots were recorded two years ago during the remap but now it is even more relaxed and easy on the throttle perhaps even some horses more due to some air flow fine tuning. But that is stuff for another thread. I posted this two years before but perhaps in the meantime we have some new members who perhaps are interested.
Rev hang is still present on this model although you adapt to it. Its noticeably apparent when short shifting up (or trying to) especially if you choose to miss out a gear. The reference to a fix by MMC resulted in an ECU that was used in the ARV6, and for a short time was offered as a very expensive retro-fit to other 3.7's. It was soon dropped by MMC, as non-compliant. Many have talked about a fix from other sources but nothing definitive yet given the MMC tweaked Mustang ECU is well locked down, and no help will come from MBE their suppliers
Despite all that power and torque you have to change down at least one gear from top for decisive motorway overtaking given the unusually high sixth gear, which I calculated would give a theoretical 235 mph at the red line!. This gearing does allow 30+ mpg though. Once you hit 3000+ rpm it will fly and the kick in 3rd and 4th has to be believed. The standard exhaust is very quiet but as you approach 4000 rpm the beast is released with ever increasing induction roar aided by the VCT.
The new 5 link rear suspension leaves a very well planted rear under hard acceleration. Some have suggested better than SSL's retro fit, but at the cost of a very firm ride to limit roll. SSL are close to offering a fix for the factory setup using dual spring/dampers to give a softer ride but sudden progression when needed, to limit roll. The six speed Ford box makes for a very wide transmission tunnel and complains rather too often her seat is not aligned with the footwell, although it doesn't worry me. Worth a long comfort test before commiting though.
The afore mentioned hard sprung and damped rear reflects in the softer front suspension but AVO adjustable dampers fix any slight nodding. Even as standard the car stays on line with hardly any discernable roll in corners at road speeds. A very rough surface (plenty in Norfolk) will have it bounce sideways a tad but generally stays where its pointing.
Like most Morgan''s it seems there is plenty of need and opportunity for customising both cosmetic and mechanical.

Don't denigrade Driver Skill. I have a friend (an ex Morgan Racer) that seems to be able to match and pass My skill in almost anything.
I totally agree. The driver is the most important element. OK this example below shows an under average Lotus driver driving an over average performance car. And then he crashed at 2:50. It is a very striking example of a hasty out-of-smooth driving style vs. a relatively underpowered but smooth driven car, the Miata who makes the video.
Regarding your 15 year old battery, that is exceptional, but an indication of how its life can be extended by leaving on float with charger/conditioner and regular use. However it's capacity will have diminished to a fraction of that when new. This will be masked by an easy starting car and it being left on a conditioner. It will suddenly let you down though, probably at an inconvenient time.
Advice, replace now.

Dear Heinz,
as i have been somewhat "involved" in that as well i can honestly confirm the connector-issue, as i was very much trying to assist them (selfish in a way, as i myself was waiting for MY ECU! Which my car has…). One further source for the mentioned rev-hang is the two-mass flywheel, which tends to "load up" a lot and gives back the stored energy (too) slowly for quick! gearchanges.
It doesn´t matter how fast it becomes, but how it becomes fast. 2015 Roadster 3.7
Hi Jochen, many thanks for this valuable information, then I don't want to assume anymore that the connection problem was an excuse. Nevertheless, it seems that the new ECU is no longer suitable for the vast majority of 3.7 Roadster drivers? (Let's assume that a connector is not a rocket science).
Roady, Richard W's comments above are pretty much spot on, his 3.7 was built just a couple of months after mine
Mine is now just over a year old & in comparison to my previous S1 Roadster (which I did 50k miles in) they are quite different & yes you have to adapt to the rev-hang, if you 'cruise' and change up below 3500rpm it's almost un-noticeable
Having spent 10 years gradually fine tuning the S1, inc suspension upgrades, the first few weeks with the 3.7 were a bit of a love/hate learning curve & I eventually fitted SSL to the front, as for me I felt the std front was fighting the new 5link rear
As for longevity, I have a friend who has an early (2012) 3.7 with well over 30k miles he has put on since owning from new & he's had no mech / elect issues at all
