Quick upadte,
The ECU and ostrich 2.0 came back from Avinitlarge.
The EPROM chip has been removed and the ostrich installed in it`s place.
With the ostrich I now can save any changes to the map direct to the ecu instead of saving to the PC then flashing it the ECU
The next things to be connected to the ECU will be the wideband AFR, oil pressure sensor and oil temp sensor.

Looking good that, I'm watching this with interest
Looks like you're getting on top of this remapping malarkey, fair play.
nice work Rob, the ostrich really reduces the work load re-mapping, so re-mapping on the hoof is almost reality for 4.4 then???

Nice bit of kit, hoping to get one myself soon.
Been going through hours of data logging and I`m starting to get my head around this remapping
As you can see from the two screenshots the I`m running really close to the figures in the map.

I’ve loaded some new values onto the ecu and logged the results, I now have a STFT that goes from – 14 to +14 but the LTFT_PL is still at +25 and generating a fault code.
One thing that has been bothering me is that the logged air flow is not the same as the air flow in the maf editor.
When idling at 750 rpm with 3.25” maf bin file I’m logging 2-3 KG/HR less than what the maf editor says it should be, also the difference between logged and maf editor values gets greater as the air flow increases. The readings I`m getting are closer to 3” maf so I loaded a 3”maf bin file and tried that and I’m logging 2-3 KG/HR less than the values in the 3” maf editor.
For example, 0.588v = 15.75 KG/HR but I`m logging at 0.588v = 13.125
So the ecu is fuelling for 15.75kg/hr but they is only 13.125kg/hr of air.
As the air flow increases the difference between calculated and actual air flow increases to a point where I’ve logged a 40 kg/hr difference.
With that I thought it would be running rich but it’s running lean at part load or I’m I barking up the wrong tree.
As I was getting no where with that I tried lifting the maf out of the housing by 2 m/m and logged the values with the 3.25” bin file, I’m now with in 0.5-1 KG/HR of the values in the maf editor at 750 rpm and 1500 rpm.
I will try and go for a good run tomorrow to see if the LTFT_PL comes down.
!00 points and a mars bar to who ever can sort this little problem out

Sorry, that was all gibberish to me, which is why I won't be doing my own mapping.

Scaling factor for MAF output correct? It's 0.0196 according to some stuff I have about M4.4. Maybe this needs to be different for a bigger MAF?
Both lambda sensors working?

I don`t understand the figures either ....but looking at it logically which this may be the reason for the wrong or expected figures!........
The pic. of the 850R MAF the sensor part which reads the volume of air is in the centre of the MAF which it has to be to read the volume correctly also the design of the sensor with it`s thicker holder would of been calculated into the equation as it will effect the volume of air going past.
The pic. of the BMW MAF holder with the Volvo sensor in, the sensor is not in the centre of the holder so therefore you won`t get a proper reading of volume!
Also if you compare the Youtube pic. of the BMW MAF holder with it`s own sensor you will see although the pic. is on an angle the sensor is in the centre of the holder and is extremely thin to avoid any loss of volume of air going past and also will read the volume accurately.
I think the reason it is lean is because the 850R sensor is off centre in the BMW holder and so it is only capable of reading less but more air is going past due to it`s diameter.
Can you not use the BMW sensor or are the electrical ohms etc different or if you have a spare 850 sensor try modifying to go deeper into the holder to be central and also trim some plastic off it?
Good Luck

I understand where you are coming from with the 850 sensor not being in the middle of the housing. The formula that I`m using with the maf editor software take in to account that the 850 sensor is not in the middle of the housing.
When I moved the sensor even more away from the centre of the housing my kg/hr readings where closer to the values in the maf editor software.
