Hi Awf,

Bootmod3 will read out your Vehicle's file and based on the ROM version it will determine what OTS files are suitable for you.

What I would suggest looking at (since the fuel quality in the GCC is not great) is the fuel quality. What sort of octane/RON do you have in Kuwait?

We, in UAE, have 98RON and 95RON. Unfortunately though, the 98RON is not a pure 98RON quality fuel, so I flashed the 95RON file and the car gave stronger figures than the 98RON file.

P.s:
98RON = 93oct
95RON = 91oct

You might want to verify the fuel quality before doing anything, otherwise you'll be disappointed.

Cheers

Hi Awf,

Totally irrelevant.

Stage 1: If your car does not have any added catless downpipes
Stage 2: If your car does have added catless downpipes

The OTS maps are as follows:
Stg1 - 91oct
Stg1 - 93oct
Stg2 - 91oct
Stg2 - 93oct

I suggest buying the maps bundle and try to switch between 91 and 93 and time your car (100-200) using a proper performance box (either Dragy or Vbox) and compare your results.

This will give you a better understanding about the quality of fuel you have. It took me months of continuous studying to realize that the 91oct file was faster than the 93oct file I had flashed.

Sounds good i do have the supporting mods for stage 2 and will get a custom tune down the road. For the mean while will test with the different oct maps

If you're planning to go for custom tune go with Cary Jordan (Jordan Tuning) and refer my name. I'm currently working on a project with him on my F10 M5.

But first experiment a little with OTS maps, and allow each map 300-500 km for it to adapt completely.

Does BM3 really need 300-500 km to adapt after changing/flashing a new map?
If I'm at the track and switch maps, the car would not reach full performance on the new map until it's driven for at least 300 km.
I thought that was with a piggyback system only (JB4, etc.).
