Do you mean you plan to swap the SMG out for DCT?

If it isn't earth shatteringly expense, then yes.

I think that will be a very good upgrade. 100% it can be done, there's an E46 M3 on Youtube that's running the V10 engine with DCT. The shifts in auto are so much smoother, and faster when pressing on. It's a good gearbox and suits these high revving engines really well.

That ought to be an improvement, although I'd be looking for a manual box like US cars had as an option - so long as it could cope with the S/C power!

Fantastic pictures of a fantastic example of one of - if not my favourite BMW.

Apologies if I've missed it on the thread (or asked it already lol) but is that running the standard exhaust or something a bit fruiter?

Interesting idea to swap in a DCT. Certainly makes sense since the DCT is the spiritual successor to the SMG.

I know of a guy who specialises in custom DCT software builds, so not your typical "mapper". You'll probably want a custom tune if going with the DCT as you'll want to up the line pressure to allow the box to hold up to 1000nm. He can get the M3 GTS software working with the box so you retain the Drivelogic settings and have the correct final drive ratio for the M5 rear diff.

Something like a CANTCU would be needed to get the DME to talk to the TCU as the S85 DME probably won't have the correct CAN interface for the DCT. CANTCU lists the M5/M6 support as coming soon, so you're in luck there.

I spent time in the states and had a manual E60 M5 for 6 weeks. The gearbox wasn’t great, the throw was too long and the ratios felt odd. When I got back the SMG on mine just felt like it suited the nature of the car so much h better, if that could be improved then it would be ideal.

So I think that a DCT conversion would be fantastic.

I definitely think the S65/S85 suit the 7 ratios instead of 6. I suspect it's similar to the manual M5 but in the M3 1st and 2nd are basically the same between DCT and manual, and 7th with the DCT is basically the same as 6th in the manual, so you've got 4 gears in between to do what 3 gears do in the manual, that does make a difference I think.

There are a few converted cars around now. Some use CanTCU and there are others around using different controllers. Evolve are looking at using the standard TCU rather than an aftermarket one.

I've driven a manual M5 - it was fun rowing my own gears, but I preferred the SMG!

Cheers!

It has a cat back stainless on it so it sounds a bit fruitier. No rasp or drone which is nice.

I'm hoping Evolve manage to sort it with the standard TCU as I'd very much prefer to not use an aftermarket TCU if I can.

So, yesterday the pumps and filter were replaced. The result? Same issue. Pretty frustrated now.

Today I have booked it in with a company who can do some live datalogging on their dyno so we can see what is going on as I don't want to blindly throw parts at it.

[TheAngryDog]

Oh yeah, forgot to mention that for some reason after disconnecting the battery to replace the fuel pumps, I now cannot turn off DSC or turn on MDM.

Can the car gods give me a break?

fking hell have you scanned it for codes?

Which module controls the DSC / MDM? Just wondering if one of them has been fried - FRM’s seem to be a liability when disconnecting batteries and I’m wondering if something similar has happened.

I scanned it with my Foxwell tool that is specific for BMWs and no codes are present. I am going to hook up Ista to see if that can do a more deeper dive.

The module is connected to a pump. I'm hoping that Ista gives me a better answer when I scan the codes tonight.

Possible flooded pump? I know it’s an issue on the smaller platforms.

It was fine until the battery was disconnected. I always drive in MDM mode.

Pull the fuse for anything related to the traction control and reinsert. Sometimes things need a hard reset after battery off/back on. My instrument cluster did this once after the battery had been off and back on - it was just dead to the world until I pulled the fuse and reinserted which woke it back up.

The saga continues.

Dsc still will not disengage.

I've pulled all of the fuses to no avail. We've flashed, recoded, defaulted and readjusted the DSC to no avail. This proves that the module is ok.

I've tried a steering angle sensor readjustment to no avail.

While scanning codes the car has thrown up an unusual one. 0027CF. This is a fuel pressure code but one that doesn't put the engine management light on. Possible causes are faulty fuel pumps, pressure regulator (both new), faulty ekp module or a problem with one of the intank fuel pipes. I will find out on Saturday.

There is also an issue with one of the floats so that will get looked at. I haven't ruled out putting the old pumps and filter in as apparently in rare circumstances, a fuel code can cause issues with the DSC. I'm also going to bridge the dsc plug to see if I can force DSC to disengage.

I've also been told that it may be worth recoding the battery in, as it may have forgotten what is fitted.

I have to say, I am getting just a bit fed up now and if the DSC issue cannot be sorted then I am going to break the car for spares.

It's little things like this that really test your mettle!

Don't lose faith; you'll soon have it sorted and back to where it needs to be

I’m sure you’ve said this before

The issues suck, man. I really hope they can get sorted soon so at least you can have a summer of hooning it around.

That's absolute perfection right there.

I miss mine badly

If I get another it'll be kept for a long, long time.

Looks nice, which blue is that?
