The reason this is so significant is that it would not show up in like for like tests on dynos or scheduled road tests following pre-selected test criteria because it introduces something difficult to define - how an engine "feels" and what it "feels" like would be best to change gear into for overtaking.
Leading evidence: 'Replace gear into' (no explicit attributable resolution; this is a reported action or suggestion). Across 1 matching discussions, The most frequently discussed action is 'Replace gear into' (1 discussions). For that action, 0 discussions report a resolution and 0 report an unsuccessful attempt. No action has an explicit, attributable resolution report under the current rules. These are forum reports and suggestions, not a confirmed diagnosis.

For reasons that we will make fully public soon - one of the most surprising results that has come out of our research and testing is that the ECO-POWER engines (both different builds but using the same principle) result in drivers generally selecting higher gears for the same speeds and remaining in the same gear (or changing down less far) for overtaking and this makes a huge difference to the overall economy and emissions.
These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

Our ECO-POWER project has moved further ahead than we ever imagined – uncovering all sorts of fascinating facts and discoveries that throw a whole new light on how to make our engines perform better with greater economy and lower emissions – but as we learn more we realise it would have helped to start out slightly differently.
We should have conducted more data tests on standard road cars before then moving on into our Eco engine versions and now not only have various other models of capacity conversion under test, but also two 996 ECO-Engine'd cars (one manual and one tip) that we are testing and gathering data on.
There is a limit to how many cars we can apply to this and how much time we can spend just driving them around for data acquisition – so it would be a big help if some of you could post on here the following for standard 996 3.4's or Hartech 3.7's.
The reason is that we have found that gearing has a major influence on economy and emissions and the chosen gear seems to change and depend on the torque characteristics of the engine as much as the preferences of the driver – so is a major factor in power band development.
(1) We are only interested in results at constant speed – i.e. 30, 40, 50 ,60 and 70 mph (usually in traffic) and would like to know which gear (manual or tip) you are most often driving in when at the above constant speeds.
(2) We don't need multiple answers saying sometimes this gear or sometimes that gear - but just need the gear you most often use at those speeds.
(3) Secondly (if it is not too difficult) which gear you usually drop down to when accelerating from those same speeds (or the same gear you usually stay in).
(4) The answers to Q 1 can be posted for example – like this Manual (or Tip) 30 – 4th, 40 4th, 50 5th, 60 5th, 70 6th.
(5) Q2 the change down (if used) when accelerating - could be (Manual or tip) 30 – 4th to 3rd, 40 – 4th to stay in 4th, 50 – 5th to 4th, 60 – stay in 6th or down to 5th.
(6) Please don't copy these figures I am interested in your own.
Finally a very happy New Year to all.

Need more detail for the 2nd question when you say accelerate. If I'm going to overtake I usually put it in the lowest possible gear, 1 for safety reasons, 2 to make a lot of noise and drama.
Maybe state soft acceleration and hard acceleration. The 2 are completely different scenarios for me.
Thanks for the 2 replies so far - actually fits in with what we expected but nice to have it independently confirmed and is actually a lot more significant than most might realise.
For reasons that we will make fully public soon - one of the most surprising results that has come out of our research and testing is that the ECO-POWER engines (both different builds but using the same principle) result in drivers generally selecting higher gears for the same speeds and remaining in the same gear (or changing down less far) for overtaking and this makes a huge difference to the overall economy and emissions.
The reason this is so significant is that it would not show up in like for like tests on dynos or scheduled road tests following pre-selected test criteria because it introduces something difficult to define - how an engine "feels" and what it "feels" like would be best to change gear into for overtaking.
That "driver feel and choice" alters the overall benefits of very different economy in different gears and turned out to be one of two significant reasons why our capacity conversions resulted in independently reported general improvements in economy as well as performance (the other being improved thermal efficiency).
More results still invited please - thanks
Baz
