2009 CRD Black Smoke after 60k service

They are extremely accurate actually.
I seem to recall mine was Diesel B but not 100% sure now.

Have another read of the manual and follow the steps, you should only have to set it up once.

Mine was within 1 KPH for speed (against GPS) and within +/- 2 litres over 140 litres per fillup (long range plus sub) unless I was going real hard off road or on the beach when a small error would creep in due to the DP Chip fooling the ECU

Interesting - I did the setup exactly as described and both DIESELa and DIESELb match what is described, - that is both result in an increase in measured consumption when you raise the RPM from idle to 1500RPM
Based on that outcome, there is no way to determine which one I should pick so I left it on DIESELa

Try it in Diesel B.

Once you have set up the Fuel and Engine Capacity the instrument should read correct fuel flow figures (litres per hour).
This should be 0.0 during fuel cut (coasting, in gear, no throttle)
Around .5 to .8 idle
Around 8 to 12 cruising
Around 26 to 40+ if you plant the noise pedal

It will need other parameters for Fuel economy IE speed correction due to tyre size etc,

The tankage and fill up adjustments is so the instrument can calculate fuel remaining etc.

OK, so if you are towing anything worth mentioning with a CRD, I assume you mean EGR block and wider exhaust?

also a chip helps and my next step is a larger intake which I will paint this weekend
