Hello Everyone,
I decided not to open a new thread.
As a hobby I modified my 2003 mini cooper r53 with smaller compressor pulley (I made & install ~15% pulley). As a next step I want to adjust sw. I use a torque lite to for logging & AEM wideband.
With help of Adriancl posts I identified few maps and make a modification in base ignition map, “throttle map”, and fuel map.
As long as the first two seem correct (I can see changes in the logs), I have a problem with fuel. I started to suspect that I did not identified fuel map correctly. Despite the changes I made, I didn’t notice AFR change at WOT. Which is definitely too high, especially between 2000-4500 rpm AFR~13,5 goes to 12,5 at higher rpm. Would you please advice? Is the map correct?

Get x4log. It's special mini software that will let you log airmass and serial afr. Gives you the exact data that are In the axis.

You mean SCT X4 Interface? Would be useful to read the load in the same units as in the ecu... But most importantly, is it the right map for fuel enrichment at full load? I changed this map significantly but AFR did not change. |

Thanks for the link. Looks like great tool for mini. I'm considering it, but I need to correctly identify the maps first.

Alex,
Software: 740903003EST6
Map start Address:7CB42 ( as on screenshot)
Org bin attached.
I still did not solve the problem with fuel...

Does somebody know the VE map on this ECU? As it only has a pressure sensor and IAT and no MAF I wonder how the ECU calculates airmass in the cylinder.
I have an OLS file for another variant which seems to use a MAF.
Currently I have a car with different camshafts and smaller pulley. At full load it runs lambda 1.1 in midrange. Anyone who has a good mappack, please pm me.

Bringing an old thread back to live.
I'm trying to get the JCW 380ml injectors to work on my 170BHp - I have the deadtime map (8x1) and the corresponding axis for voltage (5.98-16.03V).
What i just can't find is the pesky 1x1 injector scalar. Any hints as to where to find it?
(Could be a JCW210 file on same sw as a 170Bhp - then I can start hunting)

Dear R53-people
I've just bought my first Mini R53 and are planning to do some DIY changes in the maps myself via TunerProRT.
However I need to build an XDF-file first with the maps/adresses etc.
Anyone who happens to have the XDF file for the R53? Or a list of map locations and table sizes?
I would deeply appreciate it.
I will of course share the xdf and my experiences when done :-)
Thanx!!
