Hi Stan, again thank you for your reply and important information. Today I talked to my dealer and asked for him to know if I can buy a M3W ECU with the new mapping, and what price would that be. We'll see what reply I get to this query.
As far as Morgans reliability is concerned, I really can't say much because I have two extreme opposites in my experiences. Meaning:
a) The Plus 4 works like clockwork, always has, 7 years on, and I have to say that God (and a few friends and TMers) knows that I have been pushing it. Near 40.000 kms now, some natural wear (but no tear), i absolutely love that car, and I trust it to do Lisbon-Beijing-Lisbon with no problems (I need good roads though, I'm getting old and my back needs smooth surfaces, or else I would do the Dakar with it

)
To add, it is an excellent car, the kind that makes you enjoy driving, not just being transported holding a wheel and doing what the sat nav orders you to.
b) The M3W has been problematic since day one because of its exhausts(literally, first exhausts cracked 500 kms after leaving the factory). The upside is that, if you disregard the exhausts problem, I seem to have had it easy on me. Bevel Box doesn't scream, frame didn't crack, rear pulley was replaced with a steel one (under warranty) as soon as the original showed signs of wear, no compensator issues so far, well ... no issues. Only real scare regarded the Suplex suspension, and that was solved quickly and amicably with Suplex.
Now, MMC in all this is the most baffling experience. I didn't have much of it with the Plus 4 because I didn't need MMC's help and assistance, ever, after I bought that car. Only recently it happened, because a little rock cracked my original windshield, and it seems MMC (or its supplier) doesn't know, doesn't have, doesn't recall (take your pick), the correct dimensions of my car's windhield. I was already sent two new windshield frames and none of them fit my car. So, I'm still using the cracked original one. As I said, baffling.
Regarding the M3W ownership experience, the factory's attitude has been, shall we say, a bit inconsistent. I'm not going into detail about it because I would need a couple of hours to write it down, but let's keep it at that: inconsistent. I am told things have changed recently and I do hope this is the case.
Will report when I get news about the possibility of buying a new ECU.
