Talk Morgan Forums Morgan Sports Cars Morgan Plus Four, Supersport & Plus Six (CX & CXV Generation Vehicles) My23 brakes

Don't forget it is not a Morgan map, it is a crate engine from BMW and is optimised to deliver low emissions during the WLTP cycle. I always say a new engine map is not just for power but also for tractability.

I am not sure that is true, as the Supra map is not the same as Morgan's, presumably to account for extra weight. It may be remapped by Toyota before sale, but it is not the same map. The Z4 may have yet another map, I don't know.
They will all be mapped to comply with specified emissions parameters, but I am fairly sure there is a degreee of customisation involved.

This thread is drifting into the matter of re-mapping the engine computer. A good topic and certainly worthwhile to explore. Strangely I find our Plus Six very docile to drive round town and the power band great but you never know what a bit of fine tuning will do. You/I don't know what changes MMC made during the production un. I do know that you cannot go in to the car computer with Toyota software - we have tried! You need to have a Morgan version.

Ian - more to the point YES change the brake pads, and while the brake fluid change may not make a big difference, change it as the brake fluid, as in our case, had picked up too much moisture and that affects hot operation.
The only question is, "Are you going to keep us waiting until July to find out if it has worked?"

Our Plus six was unpredictable when you put your foot down to overtake in auto or sports mode. It would sometimes drop a couple of gears and you would find yourself at high revs with rear wheels spinning up. This didn't happen in manual of course, but the original map made the car a bit of a baby at low revs and the turbo didn't get going until higher revs were reached. There was no lag to speak of but the boost was too low for too long if that makes sense. This led to the snappy torque that is so talked about within the B58 community.

I apologise for the thread drift.

I’ve been thinking the same….,,,,,,,i will do the brakes April but will have to wait until July for the remap.😀😀👍👍

Sorry reply was to NZPlusSix

Barry - it sounds like your engine management computer was way out of line and you were right to get it re-mapped. As I have said our Plus Six is great in every respect when accelerating, cruising, overtaking etc.

BUT when it comes to stopping then that is another story! The car is presently at the Morgan agents to be worked on until we have better brakes. In their defense I must say that they have loaned us a near new Mazda CX-5 SUV - all the bells and whistles including "self-steering"!

I would most certainly like to hear from other Plus Six owners as to their brakes and even better those who have made real improvements. The number One thing I'm trying to improve is a reduction in brake pedal travel from the 60mm I presently have. Ever other car I have have excellent brakes - the Jaguar E-Pace brakes are almost too severe.

We have factory brakes on our Plus Six and they have no discernible issues and have good feel. Interestingly, Morgan confessed to us that they had no idea why the brakes were so much better than the ones on the demonstrator, but it had been noted by several Morgan staff who had driven it. There is no excess pedal travel and stopping is progressive and predictable. Litchfield also commented on how much better they are than they expected.
I have a feeling that the pads are not the standard pads, as the car was a development car before we bought it from the factory, but I haven't had them out to check. This may not be the whole story though and as I say, no-one at the Morgan Works had any explanation.
I will still fit the Litchfield upgrade later this year, but our car's brakes seem to be a bit of a "happy accident".

Barry, it would be helpful to compare your brake system at any point with a normal so so one.

Our 2020 Plus Six came with a fairly wooden feel to the brakes from new.. After the general recall M/Cylinder replacement the brakes "feel" seemed slightly better, but not by a huge margin. The pedal travel still seemed long though. The car then had to go back shortly after the M/Cylinder replacement for another issue and I mentioned the brakes again to the dealer, who undertook further work on them.. I do not know what was done, but the brakes now feel better again, plus there is slightly reduced pedal travel. I suspect the brakes were re-bled, from my own experience with ABS on motorcycles it can be tricky to completely purge the system of all air, even with a purpose designed bleeding system. I had a BMW K1200RS which took me two days to get the air completely out of the ABS pump.
