Okay all, sorry for another long one. I don't like to do things by halves
,
My TunerPro RT issue is now resolved, with the aid of Mark the TunerPro developer.
Referring to my VX 2002 V6 n/a 3800. Using the Enhanced versions of the TunerPro adx, xdf.
I have been looking at the whole fuel Economy and how it is calculated in the Enhanced version of the software and I thought this might be useful to help shed some light on the situation for others as it has done recently for myself.
On my cars dash it calculates and displays fuel economy as L/Hr. In the TunerPro adx it is trying to calculate fuel economy as some usage per kmph. Two different measurements which I think are unable to be compared. Hence why the readings from the TunerPro shows "inf" when stationary, something that isn't any use to myself. I know that if I am going at 100kmph and am running at 7L/hr on the dash, I am likely to be actually using about 7 L/100km from the tank (estimated only). (Previously it was up around the 11-14L/Hr which was reflected in the economy samples and worse than a friends v8 5.7L statesman.
I was trying to get what the unit of x is so I can use it to have the fuel economy in TunerPro RT display engine fuel economy as it does display on the dash (L/hr). I am close to getting the right calculated values. If I just use x/100 it is close, but not precise enough just yet. I think that the value of x to be calculated with the 0.02 Liters per hour should be of use for me going forward to create the formula for the result I want.
As I said I would, I have also finally managed to do an actual fuel economy test since I changed the Base Injector Rate to the Bosch injector spec values using the KinjFlow calculator. Now set at 554.98 msec/gram which was best for current injectors in the car.
I ensured I did very similar driving under the almost identical locations and conditions.
I previously got up to 12.88 L/100km.
This time was calculated to 10.02 L/100km.
I am also getting around 1.3-1.5L/hr at idle where before I was getting more in the region of 2- 2.2 L/hr.
To me that calculates as almost 30% fuel saving per tank of fuel.
With the engine now nearly right with the fuel consumption, I can now start to fine tune the engine for driving conditions best suited for a balance of economy and driving performance. I understand that not a lot, if any other people want economy as a priority, but it could be useful for the few that may want to for a daily vehicle to save some fuel.
