I've ordered one for delivery tomorrow. Will be interesting to try it all out! The difference seems to be really noticable!

@IanSQFIVE - have you played around with the different maps and adjusted the settings for +1, +2 and so forth? Are you running in the default map 1 +/- 0 or are your experiences based on Another config?

Thanks Ian - is it worth waiting for the new box, my car arrives at some point in Sept, so after running in probably looking to do this in October

A box between the ECU and engine just doesn't sound like a good idea to me.
I guess all these thing do is intercept key value for boost or fuel and basically over fuel the cylinders.

Sounds like a recipe for a pending disaster.
Paying someone to damage your engine - no thanks.

Companies like Diesel Tuning UK may contend your view SM, guess the proof is in what they are previously fitted and whether any issues have arisen.

 

[Snow Man]

I'm sure they would in the same way the religions contend each other...
Reads like an advert. is this a unpaid advertisers link?

"Tuning Box or as some people refer to them 'Piggyback ECU' , these units connect into the existing wiring of the vehicle generally using original manufacturers connectors , a control unit (Tuning Box) is then attached which can over-ride the signals coming from the engines sensors to the cars ECU and alter them to allow the injectors or common rail to inject more fuel at certain times and increase turbo pressure to keep the air/fuel ratio correct."

"It is also important to remove the unit before visiting your dealer as many car manufacturers will have issue with any performance upgrades."

"Intercepting the Rail Pressure sensor is the key to Tuning Boxes. The ECU/engine will control the pressure, and it uses its sensor to confirm this. This figure is vital for the ECU to known the fuel quantity. 
Adding a resistor into this sensor circuit passes the wrong information to the ECU. What was 1500bar is now reported as 1400bar, so the ECU will activate the high pressure injection pump to raise the pressure by 100bar above the sensor value. The extra pressure will force more diesel through the open injector. The Injector pump is now doing more work providing the extra pressure, and the Injectors are now holding back greater forces. The Torque and Smoke limiters have been bypassed as the ECU doesn't realise the greater fuel flow"

Its basically just a resistor....

Resistor, Piggyback ECU, Tuning Box call it what you want everyone's at it. Massive tuning company's the likes of Brabus,MTM,Hamman all offer the same thing . So if they are doing it and some manufactures even work with them it can't be that bad. Personally I would rather have a Tuning Box than open up my ECU .

 

[IanSQFIVE]

Typical Snow Man negativity.

Have you ever tuned any of your cars or modified them?

As a guide I have just done a 1200 mile round trip to Amsterdam averaging 46 mpg (600+ miles on a tank) with spirited driving........that does not sound like over fueling to me.

But anyway, you wont like it, you never will as you are dead set against anything that Audi haven't sold you or recommended.

 

[Snow Man]

Yes thanks, I've done remaps before - i don't call a resister between the ECU and the fuel pressure sensor a remap, i call it a pending disaster.
And look up what a piggy back ECU does, it DOES over fuel, thats all they do on a diesel engine... Negative or not. Lets be honest the reason people tend to use these things is to cheat/maintain the warranty provided by Audi. why pay DTUK anything - go and get a resister for 20p and do it yourself then?

The quotes above are from piggy back tuners not me "The extra pressure will force more diesel through the open injector" sounds like over fuelling to me! in a diesel engine its all about getting more fuel into the cylinder which in turn is combusted by the high temperature.

 

[davyk31]

Is an ECU map really any better? All could be claimed to put extra pressure on components that they were not designed for. Just different ways of achieving more power than standard. There are loads of cars on the roads having done many miles with both tuning boxes or ECU tuning and generally there are few issues. Other drivers will feel its not worth the risk to modify from standard and will be equally happy to leave it that way.

 

[davyk31]

Ian, 46mpg with spirited driving sounds like they have done something right.

 

[IanSQFIVE]

I generally see about 42-48 mpg (pre tuning box) daily, we didn't hang about getting to and from Amsterdam though

 

[Snow Man]

ECU is parameter based and allows direct control of the engine based on the control table and is variable based on may factors (or sensors).
Agree both methods put more "pressure on components", a race engine only has to handle a few 100miles, road cars much more and clearly VW dial back to provide maximum protection to the components (or them in terms of warranty).

You are paying for the profiling or mapping i.e. extra intelligence that goes into a remap rather than a generic "CRD box" that fits onto any Audi.
That said i believe the V6T has the first of a new Gen of multi channel control systems fitted.

I offer no moral judgement either way on those that do or don't do this. My very simply point is a software ECU upgrade will have much more intelligence built into it rather than a box thats simply tricking a pressure sensor.

This post smells like advertising spam to me, but as it is well written spam I shall let it stand.

I'm with you there Snow Man, I recall having a Revo remap in an A3 2.0TDI/DSG a few years back and know that their improved ECU map reduced torque output when in the lower gears to save the transmission from excessive loading, doing the job properly these days is more than just getting more raw performance from the engine.

I'm with you on the spam..

 

[?? SQ-BEAST ??]

I was likeing the sound of that box,if it's spam there doin a good job 😄

 

[IanSQFIVE]

Spam lol, you guys make me laugh. I suppose my car is a fictional car? Bare in mind I picked up top 10 Audi at MIVW show in Holland, one of Europe's best shows, and I have the most modified SQ5 in the world, I'm not just going to throw any old rubbish on my car.

The problem with a remap is the ecu needs to come out of the car, Revo won't warranty the job if it goes wrong, and an ecu isn't cheap.

At present the revo map is still a beta version in testing, no numbers or price available.

MRC were a joke to deal with, and I'm not the only one who thinks this recently!

I am receiving no financial gain from DTUK, I am simply giving my thoughts on a product I have used.

 

[?? SQ-BEAST ??]

The box sound like gr8 value for the money,especially with your figures Ian 😄

 

[IanSQFIVE]

I haven't had the car on a dyno so cant confirm the performance figures however I certainly notice a performance gain, the car pulls real strong and the slight lag has gone.

Economy wise I have noticed no real increase or decrease, I still get 600 to a tank.

Next mod is an intake for the car.

@IanSQFIVE

Interested in this box but I understand it has adjustable maps? What settings are you using?
