I've spoken to Llynch, he has had his tuned successfully so I can only assume you can expect some dyno graphs soon
My centre diff actually blew up before I got the chance to have it remapped, so it's going to be a couple of weeks before mine is back on the road.
Hey guys sorry for the delay.
I had a good day at DMS, they managed to do most of my requirements.
Top speed de-limit.
CEL on oxygen censor for when I install the de-cat.
Rev limit increase in neutral.
A few pops - but this wasn’t achieved.
And what you are all waiting to see, the results of the remap.
It just pulls and pulls from 4K onwards. Really is amazing. So much smoother than the dtuk box.
Next is the turbo as that is the limiting factor at the moment. As well as the fuelling but I haven’t found a solution to that yet.
I would recommend WMI, but that isn't really an option unless you're running a JB4 unfortunately. They've had some incredible results with WMI and turbo though, running 10.x 1/4mi and sub 3s 0-60!

For sure. You'll be running 600bhp with ease from what I've read on the turbos

Wtf??? Seriously?? I was thinking about 550 but that’s crazy. I’m assuming that would need other hardware modifications to hit that
Others have said 500awhp, so 600bhp should be achievable. That's with DP, FMIC, and intake. Wouldn't run a sports cat with it to be honest.

Just to confirm the first plot is stock software plus all the hardware in your signature?
Very nice, have you managed to do any dragy testing yourself yet? Be interesting to see some times. I take it you went for a stage 2 because you have all the mods for it.

Not yet bud, I've ordered a dragy so as soon as its here, ill be giving it a blast.
Yeah stage 2, I did everything in hope that they would crack the ECU and I would be prepped for it.

whats the limit on the gear box? I thought it could handle up to 650-700ish lbf∙ft or is that another variant of the ZF8
Definitely. I think it might actually be revo doing the map but don't know for certain.Exciting times!! Looks forward to the facts and figures
i have 695nm for now. when the ecu reads 550 (i think nm) it goes into limp mode.
When a gearbox tune is possible the limiter can be raised and can be tunes further.
Maybe it is the current gearboxfile or not.
Can you read your software version ?
I will think it's a limiting issue at too low of an RPM. When I get my car back I'll check what version mine is running for you. I'll also let you know what figures I'm running.
Sorry should've clarified, it's in for today and tomorrow!
I've gone to a local tuner. I won't have the car until tomorrow night so I won't know until then.
The remap might not 100% be done by tomorrow as I've had them put all the hardware on alongside spark plugs and brake pads. I'm traveling on Friday so told them if they don't have it done by Thursday night I'll book it in after the weekend when I'm back.
I haven't heard anything from them yet so I can only assume they'll be able to remap it in time.
Awesome really interested in all this please keep us informed these cars with a remap would be an animal
430bhp, 550Nm.
I reckon it's actually about 440-450bhp, the car dyno'd 335bhp stock.
Torque is lower than I expected unfortunately but it conforms to what @Rogier140 was saying. Until a TCU tune is out I won't be going any higher by the looks of it.
I'll post the dyno graphs tonight.
Would've preferred more torque but the TCU locks it to 550Nm unfortunately. It pulls very hard at the high end though, it's amazing!
The tuner is interested in doing more work to the future and says they'll likely have better maps too as it's still very early with this car. They were interested in remapping if I put a hybrid turbo on it too.
Overall great experience with them. Prices were pretty damn good too

Glad it’s all done now bud! I bet your well happy with the results either way. Did you manage to get any crackles added in?
Not sure the TCU locks to 550Nm though as mine was about 630Nm.
Definitely happy
I asked for some crackles on overrun, they said they didn't know if they could definitely do it as it's obviously very early and they didn't want to damage anything of course. I do have some crackles - more than I remember with the decat but I'm not sure if they actually added them lol, forgot to ask.
Me and @Rogier140 have found it goes into limp after 550Nm but he managed to get his higher, his tuner somehow fooled the ECU. I suppose yours did the same

That is interesting well they are coming out to visit me next Friday to add a bit of crackle now I’ve had the decat installed. I’ll ask them how they got past the limit.Definitely happy

Awesome bud cheers.
Momentum. I'm not sure, it could have been. My car is slower than others in the DTUK group so it makes sense.
I done a RR day with some S4 b8/b8.5 owners and a b9 s5 ran and you could see it pull timing that also ran 335bhp. These cars need bigger intercoolers shame Audi put such a small one on.
Actually, you've just reminded me! They said that it was pulling timing on the stock run due to the intercooler. He loves the Wagner though, said he couldn't even get it to warm up at all. So that's good to know

Have you thought about the TCU+ from DTUK?
