Yep will do.

Another tuning box at the same price: http://www.ebay.com/itm/Diesel-chip-tuning...27da712079

Any info about this company? RRS 2006 2.7 HSE

I don't have any info about that company but I can say after using it for nearly 2 weeks now my mpg is consistent at 24 to 26 from the 19 to 21 I was getting before.

got mine in today...was at the back of the engine...

this has made a difference...definitely less turbo lag and feels more responsive. Or may be that was just me deciding to put the foot down more

For the price i would say it is worth it.

Like Karan would like to see if it makes a difference to my mpg over next few weeks.

Tried to do a 0-60 with the chip? So we can see the improvment:) RRS 2006 2.7 HSE

Karan, have you measured your fuel economy properly (brim to brim) or merely relied upon the vehicle computer?
As I mentioned earlier, these boxes gain the extra power through over fuelling the engine. It works, but at the end of the day it's your engine, and some are more sophisticated than others in what they measure and what safeguards are built in.
Many claim to be digital but contain no more than a simple resister. The less sophisticated ones can also cause more "diesel knock" when the engine is cold

Below is an extract from a publication summarising how they work. All of the limitations are overcome by a correctly calibrated remap since this will take into account adjustments to many other engine parameters monitored by the ECU. For clarity I'm not saying "don't buy tuning boxes" but having been there its a place I'd never go again!

Diesels aren't too fussy about Air/Fuel ratios, they will often continue to make power when incredibly rich, and producing huge clouds of black smoke. Take a look on Youtube at some of the big power Diesel Drag cars and trucks. In OEM Diesel tuning for the road, the limitations are usually based on the amount of smoke produced, and the amount of power the chassis can handle. Big BHP figures on a diesel are easy to make, and choosing the Tuner with the highest figure can sometimes be just picking the bravest. It's easy to be brave with someone else's engine. 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, and as mentioned, for a diesel, more fuel = more power. There is safety factors and tolerances built in, but in all cases, 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, and more interestingly, the MPG is screwed!

Economy and Tuning Boxes

From the original calculations in the ECU, and the Vehicle Road Speed, the ECU will be able to calculate the quantity of fuel used per unit of distance traveled. But what happens if the quantity of diesel injected is higher than the value the ECU is expecting? In this case, the economy will be overestimated as the ECU thinks it is using less diesel than reality. As with most external changes, if one calibrated component is disturbed, the knock on effects will be far reaching.
That's not to say that there isn't an increase in economy, there will be changes, and often the economy does increase, but certainly not to the level that the On Board Computer or Trip Computer thinks.

Tuning box still going strong without any engine prob?
Could you do a 0-60 to see if its about the same as a ECU remap on 8.8 sec? RRS 2006 2.7 HSE

Everything is running well

Will give it a try when I can.

you do that;)  RRS 2006 2.7 HSE

Hi Guys I could really do with someone pointing me in the right direction as to where to find the correct plug. I have read through the thread and im sure its at the back of the engine being an 06 plate.

My photo seams slightly different to the first 2 and I just want to make certain im looking at the right plug before causing myself some issues



My guess is that its located behind the silver rail running across the photo

Here is a close up of the plug I think is the right one

Hi

Mine was at the back of the engine in the middle too. It looks like the right one. I ended up getting my mechanic to install as it was awkward to get to.

Thanks Dhups

I think I may be the same as I have spent far to long this afternoon attempting this and I need to get one with cleaning the car before it gets dark

Jay

you guys still going strong with this chip? any of you done a 0-60 yet to see the difference?

On the recomendation of a collegue i am thinking of buying a Speedhawk system.

Anyone got any experience of them and if so what sort of results did you get Got:
2006 RRS TDV6 HSE, 2017 AMG C43
BMW 1200GS

Not Got:
Sense, money
