Well, after playing with the A1 185 for the past few days, I thought it time to put in the TMC box.

It is a little fiddly (lack of space for Camshaft and Manifold sensors) to fit, but it took me no more than 10 minutes, and that was with checking that the cables dont go near any moving parts or hot areas.

And off I went to play on the "bahn"....

Now, the 185 ps A1 is a great, great car in its own right. Its small, its light and the S-Tronic gear box is a delight, especially mated to the 1.4 TSi engine with its Super and Turbo charger delivering "base of your back" acceleration. Its very linear in the delivery of power and provides a great "hot hatch" feel to the car.

In its base form, as we all know here on the A1F, it delivers a 0-62 time of 6.9 seconds, which is VERY competant from such a small engine. Its frugal on the CO2 too, at only 139g/km which means its econmical! Delivering an impressive 47mpg (claimed) on average. I have to say that this figure is somewhat aspirational rather than real. We've managed an average of about 32 mpg, but then again, have been a litte "heavy footed" in our driving this week - couldn't help it with such a great engine noise!

So, what happens when you put this little red box under the bonnet? Well, in the first place, the 185 is a little fiddly due to the location of the sensors, but its not impossible for "jo public" to fit themselves, just have to be a little dextrous with your hands - BUT DO THIS WHEN THE ENGINE IS COLD! Seriously, you'll burn your hands! Make sure that all your cables are not in the way of any moving parts, and if you chose too, secure them with a few cable ties. You can then fit the red box to the pillar above the wiring box on the right of the engine bay, with the supplied thick cable ties.

This box, compared to the 122ps version, only has one dial, which comes set to "6". We left this as that for our test. So, fitted, we started the engine and popped off to the wonderous land of "Die Autobahn", which is located a mere 2kms from the offices here in Munich.

Immediately, even in "D" the engine felt more eager - eager to get on the open, unlimited, autobahn. The first 2km of bahn are restricted to 60 / 80 then 120, then........nada. The ford transit that sat on my arse as we "tootled" along at the requested limit was a little stunned when this Grey little A1 dropped into sport mode and disappeared rather rapidly into the distance, hitting 200kph in little time what so ever - a tad quicker than in its standard form. The flexibility of the engine combined with the S tronic box just makes this car a real pleasure to drive at speed - its planted, solid....firm.

It is a very capable "hot hatch" in its normal format, but with this little red box, it feels like a Berocca Boost has been dropped in the tank! Given that this car has a very respectable 0-62 time normally, with the TMC RED, its now creeping in the S3 / TTS territory for road performance in all gears. The torque in the engine means that it is very very able to nip out in that gap you spotted, accelarating safely and precisely. The only thing that starts to creep into this equation now is the front wheel drive...the power becomes a little too much and you start to get a hint of torque steer at higher revs. This isnt the fault of the TMC RED, its inherant of a FWD. This is why Audi could NOT put the S name to the A1...it is not and never will be an S without the quattro.

All this time, playing hard with engine, we've not seen any change in the way the engine is consuming fuel, its pretty much on a par with its standard format - even at 200kph +.

Now, while out, we wanted to try the Launch Control that is usually asscociated with the S Tronic (previsouly DSG) gearbox. In theory you can set the car up to manage a controlled "launch" of the car while giving it all barrells. So, naturally we wanted to try it out - after all, it scared the begezus out of us in the TTS last year!

ESP Off - Check
S Mode Engage on STronic - Check
Left foot on brake - Check
Check road is clear - Check
Right foot to the floor on the gas - Check.....

Engine doesnt rev to the 3500 - 4000 that normally happens, it senses that the car has its brakes on and backs off the gas. Tried various combinations, but no, didnt work. We will try the LC again, without the TMC box, to verify if the car (with over 8000kms on) does work in standard format.

So, back to the TMC. We found a stretch of the "bahn" to check the 0-100kph (0-62mph). Very impressive indeed. From the standard 6.9 we were able to eek into the 6.3 - 6.4 region, which for a box that costs 300 UKP, is a superb gain, and soooo easy to fit!

We have the TMC box fitted to our 122, which brings that car into the same torque playing field as the 185ps A1, but "only" brings it into the 150's in terms of power, meaning that we're able to improve the 0-62mph to about 7.8s. Its no 185 but it gives the car the flexbility its eager to deliver.

The 185 however, with the TMC RED, gives it that something more, that je ne c'est quoi, to the car's character. In its standard form, it rocks, and wish that it was available when the 122 was ordered. With the TMC its a little monster, and if you have a 185 and you think you're happy with it....its just showing you its potential. Get the TMC RED and release its soul.

do you recomend the tmc box or go and get a revo remap? i am undecided on which one to get and was wondering what your opinion is?

Issue is with other solutions is that you have to take it to them, and they have to bypass the chip encryption...which sometimes means opening the ECU. This invalidates your warranty :(

TMC is literally plug 'n play.

We have a bluefin here in the office, but it cannot get past the encryption :(

im very interested in the TMC and just wondered when you fit it to your car and you take it into audi and you take it off does it damge the ecu? taking it on and off? thats the only thing stoping me and also do you need to tell your insurance company (im guessing yes)?

Not while driving, no.

The taking off of the unit is painless, and wont "upset" the ECU, so dont worry about that aspect. It is literally 5 mins once you have the knack :)

I can confirm this.

Installing the unit is very easy and apart from plugging in a couple of plugs there isn't anything else to "install".

The 'hardest' part for me was working out exactly where to play the much smaller TFSI 122 model tuning box.

When the car does have to go in you simply have to do the install process in reverse. The longest part will be removing all of the zip ties.
