some of the feedback from s4/s5 owners

Installed TCU upgrade this morning. What a difference. Pulls harder in low gears, dead spots gone, shifts way smoother on harder acceleration.

Quick feedback on our side of the pond.
On B9 SQ5 have everything DTUK, from tuning box , pedalbox, and now TCU tune.
Though only have about 30-40 miles into it. It mainly wifey’s ride.
Things I notices..
Gears run smoothly on normal city drive.
Gears change quicker. But that still all depend on the driving condition. Little throttle will still have slow shift, but quicker than stock
Definitely feel the there is more Torque. Especially at lower RPM.
When gears changes. The delay is gone. And power comes instantly.
Did not have a chance to drive it like a Maniac yet.
Once I get more miles on it, I will report again.

Yeah have to agree. Pulls harder, gear changes better, Launches are ******* quick! jolts my head right back and just trying to work out of the box and Bluetooth will give me a time! .
Just got home and it does really complement the box. Did a good handful of launches and it’s really quick, scary quick. Feels like the box has grown in power! Feels like there is Much more torque. Manual for me is most impressive, sadly i just kept running out of road! The car just kept pulling and pulling the only thing I would say A few gear changes were still laggey going from 1-2-3 but mainly from a standing start. Once rolling didn’t have any issues
“4th is now like another 3rd”

Flashed yesterday afternoon – did over 300 trouble free, fun and enjoyable miles today – with some very smooth and quick gear changes, noticeably less lag and generally a gearbox behaving and feeling like it really should do. No downsides noticed – and on a good (efficiency and ACC) 70mph run on the M4 was seeing 40+MPG. Thanks!

Ok Gents I just went for a brisk 20 mile drive on some fast A roads. I’ll reserve writing a full review until I’ve done a few hundred miles but I will say of the 5000 miles I’ve put on my car from new I think the last 20 I just did were the most enjoyable. I test drove a new Panamera 4S recently which ironically basically has the same 2.9L V6 engine in as the B9 S4/5 and my gearbox now feels and behaves like it did in the Porsche. Manual is now completely sublime, you can feel the extra torque in all driving modes and the changes are smoother both at low speed and when pressing on. I’ll report back again when I’ve done some more mileage but initial impressions are if you’re sitting on the fence about this don’t, just do it.
Did a 30 mile drive this morning to work and the TCU has completely transformed my S5. I am so happy with my car now. The gear changes are smooth, fast & you can feel the extra torque but most importantly it now feels like there is a direct connection between the throttle and gearbox. Thanks Andrew you ******* legend

Some initial perceptions from my drive into work this morning. I’m driving an 67 plate Audi S4 avant with the tuning box (2+2) and pedal box on sport+1. Drive to work is about 10 miles, 8 of which is motorway driving. Gear changes driving out of town are perceptively much smoother and quicker when in town and driving normally in Comfort mode. On the motorway, not much to tell, but I did an overtake of a lorry whilst driving at 60. Foot down, pulled out and the drop down in gears from 8th to 4th was much much better, and without the 0.5 lag from before the TCU flash.
I’ll post another report after my drive home from work, where I intend to “drive it like my gran stole it”

I thought that since I’d been running the gearbox tune from DTUK on my S4 for a while now I’d give some feedback so others can decide if it’s a good option for them.
Basically it feels like it’s tightened up the gear shifts. Downshifts are significantly faster and therefore smoother and I’ve found that it’s much smoother when travelling slowly and in traffic. I’ve also noticed with the ‘butt dyno’ that the pull in gear is stronger, potentially being down to the torque limiters being raised slightly to let more of the available power through.
Thankfully, the most annoying aspect of the gearbox has also been addressed by the tune. The initial lag is better, but the transition from braking to accelerating (like when approaching a roundabout or junction) is night and day. My car used to pogo if you tried to get on the power immediately after being on the brakes but this doesn’t happen anymore thankfully.
I can’t comment on the outright speed of the upshifts being faster as advertised because I’ve not had the chance to do a full launch control (that’s the only time I noticed the shifts felt sluggish), but I’d imagine that much of the smoothing at low speeds is down to the shift speed being increased.
For installation it took all of 6 minutes and that included the 5 minutes for allowing idling of the engine afterwards.
All in, I’d definitely recommend it if you have the spare cash and it can be supplied for most makes of cars rather than just Audi. It also works with S-tronic and has similar positive effect by all accounts!
If you decide to buy, feel free to mention you read this review and it might get you some money off.
If you have any questions about my experience of it, just ask!
