HERE’S WHAT OUR HAD TO SAY IN HIS TUNING REPORT.

RE D40:

great results with some interesting tuning techniques on the automatic version.

To start, the produces 238ft/lb torque 126HP  at the in standard trim .  With a It Performance Chip the max figures we achieve with the Diesel Particulate intact, and without having the throw a high catalyst code was 280ft/lb torque 140HP.  this power level/tune it give this error.

Well then we had a play  

   We removed the DPF from the fitted the Chip It DPF Delete Pipe. The factory DPF appears restrictive to say the least.  After in the new Race Pipe we dyno’d the car with the factory tune in place.

Guess what?  figures went to 280ft/lb 138HP the same as having the vehicle chipped), but it a belch of black smoke time you took off.  whilst driving or at top end).  We using the Chip It Performance picked up further throttle response

  Then, we spent more time for torque with extra turbo (unique to Chip It Modules) in the top end to get a final result of 325ft/lb and 152HP … WITH NO ERROR AT ALL.

When we delivered the vehicle to the owner he was delighted with the As an extra bonus, and the reason why the Pipe is fitted, is the economy be far better than the factory as the PDF is no longer needing to be cleaned by the of diesel after the exhaust has opened (POST BURN

This extra squirt of is not there for any other purpose than cleaning the DPF.  also add fuel to reduce Nox during the stop start of the EURO 4/5 drive cycle testing.

Yes, sounds weird, but fuel does reduce Nox as we learnt at Orbital Corporation known, every time you make a result with one emission you always a negative result on at least one of the 5 emissions.  So we would say the Particulate Matter (black smoke or PM ) through the roof when reduced the Nox, so they add a DPF (on the autos not the manual s) to catch the PM … crazy hey?

  However, it is the of things manufacturers need do to EURO 4 5 requirements.

As mentioned, to the DPF function correctly, every 350 kms or when the filter is partly need to inject diesel the exhaust to heat up the DPF to clean it this doesn’t happen emission cycle testing and so get away with a “pass” and a looking economy reading but this is achieved in the real world.

Their litres per fuel usage shown on the sheet doesn’t show during the Post Burn Cycle and so when you finally get to the new car home, you NEVER get to see the nice figures they tout. You get with 16 – 18 ltr/100 as a minimum.

However, we now have created a created a lot more power by removing the DPF, re-tuning the with the Chip It Module for far power and with a far better curve plus more turbo response.

created from scratch an result that will a doubt bring back the great savings these mod ern diesel s were designed to achieve.   we fully recommend the factory DPF be when Chipping the autos, the regeneration cycle will the rear sensor.

We can provide a Pipe for DPF removal, EGR blanking to add better fuel burning and turbo response, and a Chip for the to suit all combinations such as:

.  Keep the PDF.  (with the and re-tuned it will be better for the DPF keep it cleaner return fuel results)

.  Removing the (with our DPF delete Race as it doesn’t throw any lights or and produces EVEN MORE

THIS MOD, OF COURSE, IS FOR USE ONLY! 

DPF Delete Race Adds 12HP AND 40ft/lb (8.95Kw AND 53NM Torque). If with the Chip It Tuning increases gain by 26HP AND 87 Improves fuel economy dramatically. See the page of the site for purchase
