Got a mail from BMW 10 mins ago, the Ppk for my car is no longer availabil , they suggest a new kit ...... Will look into it now. Phantom pm me and I will forward jou the mail. There is defnetly a prob with the 330d Ppk kit.

Ok so 7000km later and sanity has prevailed. Some more observation.
My fuel consumption on the car used to be an incredible mid 4 litres per 100km.After the PPK you struggle to get high 5.
After getting my new F30 335i I now see what the problem is.On the standard ECU when you take your foot of the accelerator your revs fall to idle status as if the gearbox has been disengaged.This function is only on ECO PRO.
I went to the dealer yesterday and we took a F30 330d off the floor to test that this function is on the diesel car as well as on the 335i.
The function is there.We then proceeded to load all the updates from BMW onto my car but to no avail.Therefore the software on the PPK ECU to my mind is a botchup.Why not still have the economy on the ECO PRO and just up the power on the sport and sport + then you have the best of both worlds?
Fuel consumption is a major part when people consider a daily vehicle
as it comes into play all the time.The more power from the PPK kit is something you may enjoy 10% of the time.
Based on this info i cannot recommend this kit until they fix up their software and am probably going to put my standaed ECU back into the car.
Expensive exercise but at least the brakes and bigger intercooler are not wasted.

Ok so if I understand you correctly the rpm drops to idle, my car defnetly does not do this in Eco pro mode or any mode, It does feel like it coast, but the rpm stay the same , even goes higher on steep down hills at any speed from 60 to 140kph.

This is an ECO PRO function only.Basically when you leave your throttle the gearbox disengages and your RPM drops to 700RPM.
The second you apply either throttle or brake the RPM jumps up to the RPM of the gearbox.
On my F30 335I with this function car does 6,4l/100.Same stretch of road in Comfort mode that does not have the function fuel usage jumps up to 7,8l/100.

If the function disengages the gearbox, it is in essence idling? My understanding prior to this discussion was that if your foot is off the accelerator there is little or no fuel being used as the engine is being turned by the gearbox. If it disengages the gearbox and idles it will have to use fuel. That would mean that idling uses less fuel than when your foot is off the accelerator?

Hope i explained it correctly? Is my understanding correct?

OK so you're travelling at 120km/h with revs at 2100rpm.Normally if you take your foot off the accelerator your revs will come down slowly as your car decellerates.With the new function your revs drop to 700rpm straight away and of course less revs use less fuel.If you had a manual car this would be like pushing the car into neutral every time you lift your foot of the accelerator. :thumbs:
