Yeah have to agree. Pulls harder, gear changes better,  Launches are ****ing 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

(this item is not suitable for Manual or CVT transmissions)

The TCU+ Gearbox Flash installation guide.

The TCU+ Gearbox Flash is an OBD flash tool that not only unlocks manufacturer’s transmission settings within the vehicles ECU to give smoother and quicker gear shifts, increased torque and performance. It also now provides an adaptation reset as standard which helps you get the most from your car. This provides an essential tool in your vehicle’s modifications journey.

The TCU+ Gearbox Flash has three functional requirements.

• The need to improve and optimize the gear shift speeds and modify torque settings in the modern automatic gearing systems to improve the overall driving experience.
• The need to create a simple to use Plug n Play OBD solution which is easy to install and at an affordable price.
• Provide the end user with a tool that allows the vehicles adaptation settings to be reset to factory, simply and efficiently.

How does it work?

The all-new TCU+ Flash Tool integrates with the vehicle’s onboard communications network via OBD to access the ECU, TCU and Convenience modules to adjust/reset the shift strategies within the OEM control components to “point” or “re address” these strategies to the best and most optimal settings.

This includes changing the transmission shift speed pointer to a faster/different setting. The internal components that make up the mechanics of the transmission have a wide range of tolerance and multiple settings allowing manufacturers in most cases to use single components across a wide range of vehicles allowing them to reduce production costs across the group. They all contain similar if not the same generation components, usually built in the same factory, but have model specific software strategies that are used for their specific application.

The New TCU+ provides a Clean Start Point

Over time your vehicle may have adapted to a slower shift due to a previous owner driving style or the way the vehicle has been driven over time. Unique to the new TCU+ Tool we have added the extra function of resetting this to provide a ‘Clean slate’ install. This is an essential step when modifying or tuning as it gives the user a factory clean reference point and base line.

What’s all the Torque About?

Torque Limits are also set in various systems and control modules within the vehicle; this is set by the manufacturer and is one of the easy ways to electronically limit power in certain models of vehicles. This allows the manufacturer to release many different power variants with different driving characteristics with only a single engine. This is a much more cost-effective way of creating a vehicle range without the need to manufacture multiple engines at different power levels. We all know how many power variants are available for the VW Golf 2.0TDi for example. Same engine different software settings.

The New TCU+ Releases Lost Power.

By simply unlocking, resetting and amending the torque settings to the various other manufacturers settings we can allow the vehicle to produce and deliver power safely and still stay within the manufacturers specified limits. This style of ‘derestricting’ ensures that key settings such as clamping force, slip, torque limits, shift speeds etc. all remain within not only manufacturers spec, but also component spec, thus never exceeding safe operating tolerances or shortening component life.

How do I Install the new TCU+ Tool?

The new TCU Flash device is a simple Plug in OBD Flash unit. Plug the unit into the OBD port, wait for the procedure to complete and then remove from the OBD slot, it really is that Simple! Once installed the tool is then locked to that vehicles VIN (Vehicle Identity Number), which can be flashed multiple time to refresh the upgrade if it has been erased by the Main dealer or Manufacturer.

Installation Procedure

• Switch ‘ON’ ignition, but do not start engine. Ensure dashboard/ignition lights are illuminated.
• Locate OBD port (on board diagnostic plug) usually located in the driver side foot well.
• With the ignition still in the ‘ON’ position (engine NOT started) insert the flash tool into the socket. You should hear an audible beep and the LED will illuminate. The tool is now active and has begun to program.
• Once the upgrade is complete the unit will begin to beep constantly confirming the process has completed successfully and the LED will switch OFF.
• Remove the flash tool from the OBD port and switch ignition into the ‘OFF’ position
• IMPORTANT – Start the engine by turning the key only. DO NOT PRESS GAS/Throttle/ Accelerator Pedal and allow to idle for 5 mins. On some vehicles you may hear the engine hunt/rev in this time, then eventually settle.
• After 5 mins of idle you can now drive the vehicle using the full rev range and, in all gears, and modes, in both sport and manual. The vehicle will now begin the adaption phase and adjust to the new upgrade. This phase can take anything form 10 – 100+ miles depending on vehicle. Once complete the vehicle will feel sharper and more responsive.

I received my TCU+ Tune from DTUK today and will install it to use this week. I have not purchased the device to eliminate any lag, or to improve the gearchanges, as I’ve been happy the way they are, but to go with my tuning box. I am hoping it will allow for the increase in power and torque the box gives to be implemented upon better.

On my short urban drive to work I have noticed a difference immediately despite the gearbox still having to relearn. Much better in traffic, smoother and less ‘snappy’ or jerky. Also the gear changes are nearly unperceivable and I found myself looking at the gear indicator to see which gear it was in.
More to follow, have to try all the modes and manually using the box…

Whoa, sport mode is bit feisty…

 

More to follow..

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

Update on the Jag install. Lower speed changes are far smoother. Kick down is much faster. I also seem to be getting 8% more to the gallon.

It’s getting better mpg, even though I’ve obviously been testing acceleration and gear changes. Average mpg is set on auto at the moment so it does it for every journey. Whatever the reason, I’m getting extra mpg… Which is pretty important when my average is 31 an added bonus is the car is smoother, faster and happier in town.

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!

what a difference!
Smoother and shorter up shifts and down shifts, more torque.

Well i went over typical scottish country roads to collect my trailer. Now heading south on the motorway. But whatta difference its made to the gear changes. I was planning on doing a before and after video but never got the chance. Once my trailer is loaded i will give more feedback.

OMG !!! Guys if tou have a dtuk modul for the motor you need the flash for the gearbox !!! It’s fantastic.. Best $$$ spend on my car

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.

Going well . I used to experience slip between gears .now, when the gears change, it is instant acceleration . Gear changes at low speeds are seamless . 435d

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”

Dan in UK – S4 B9 S4 3.0 TFSI 354PS S-tronic

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!

Ok. 30 seconds to upload. 5 mins idle. 1 mile up
Road and back.
Smoother very low speed shifts in traffic. Quicker pick up in gear. Quicker short changes up and down. Stop start still works. Coasting disengage still works. Will give it a proper run tomorrow. Initial signs, has done exactly what I wanted it do.

Great work as usual Andrew

 

Right, part 2 of 3 updates on the TCU. Again short regular trip this morning from cold with lots of low speed junctions and roundabouts….cold, low speed changes much smoother, slow approach and pull away much much better. Comparison on old with same throttle input and time over same distance results in higher terminal speed. I have not been above 45 and for me it wasn’t about outright performance as I have a B9 2.0 Tdi but it is just quicker for the same input without trying at all….will do a long run today and see what it’s like at speed. Who knows the secret of the black magic box……
