Modified R53 Auto

Hi chaps,

I've been having a poke about with WinOLS in hope of improving the map on my R53.
The car is pretty modified, and I previously bought a map from a guy on the owners group. But it's the map is pretty much useless as it over fuels heavily in open loop so now the car looks like a diesel if I hit the gas hard. Not cool!

Perhaps someone on here can do a good job.

I would ideally like to see a consistent AFR in open loop, with a low % long term trim.
Torque limits removed at 3.5k rpm up, with a faster response from the throttle body vs. pedal input. (I use a hand control for the throttle because my legs don't work which makes the drive by wire feel very sluggish. I have a "Sprint Booster" fitted which helps but would like to do this with the ECU if possible.)
Currently I have overboost warning P0108 code muted also due to the mods.

Mods list:
-20% pulley (Auto revs out at 6800 so charger speed with -20% @ redline = manual with -17% @ redline)
Fully ported intake with enlarged airbox and filter
Ported head
Newman PH1/2 camshaft
Red HT leads (it's faster, right?)
Ported aftermarket manifold
cat-back exhaust
Intercooler/etc.
I have original 330cc, plus 360cc and 550cc injectors available to use, with the amount of over fuel I'm thinking of switching down to the 360.

I have my original map plus the modified one available if it helps to look at.

Thanks in advance, my dudes.

I can do a good job for you.First of all you must use bigger injectors than stock 320cc.Need 380cc , 440cc or 550cc injectors, because your supercharger with 20% pulley produce more air.Newman PH1/2 cam is a good choice.You get P0108 i guess because of bad remap.20% reduced SC puley is a strong mod ,so tuned file is not easy to be done.Siemens EMS2K not use torque limiters.Tuning this ECU with ECM Titanium is a big mistake.If will use 380cc injectors, can get around 225-230hp at crankshaft.Also the gas pedal sensitivity can be modified to replace the Sprint booster.For more details , send me pm here.
