EDC15P from AVF engine: TQ limit map same in %,BUT at least the % is linear,but still :D
Smoke map still +20% on whole map. DW looks good.
EDC16U34 from 1.9 TDI BKC: Tq limiter same(in linear %),DW and TQ limiter values are same as in TQ limiter. In DW they should be higher. Boost maps also in linear %. Nm to IQ map cheated - added IQ values,but NM axis left stock.
EDC17C46 From 2.0 TDI 140HP engine: DW looks good(slightly bigger values than TQ limit map),TQ limit again as in previous ones(linear % change),boost maps also same linear % changes,NM to IQ map cheated again(values in map increased,axis left stock),Rail maps increased by 3%(don't know why exact areas in map),lambda map again 10% changes.
BMW DDE 3.0(EDC15M from 320/520d versions with 136hp VP44): DW maps last two columns changed by 21.4%.
TQ limiters increased by 30%. Same with TQ limiter for limp mode - 30% increase. Smoke map- almost whole map changed by 9%,last column has some different changes. Also MAF axis values changed(which is good). Some values in smoke map are little bit lower than TQ limiter values. Boost limit - 9%. Boost maps not changed at all.
EDC15C4(BMW E39/46/53 DDE 4.0) - Almost half of Boost map 9% changes,Boost limit map - 10% changes,DW maps 80% of pedal position column increased by 9%,last column 7.8 to 9%. All Smoke maps increased by 20%. All TQ limiters increased by 30%. IQ limiter increased by 12%.
So yeah there's plenty of updates and changes needed,but it's better.
Didn't checked EGR or DPF off functions yet.

What I could recommend from my side : find someone who could do a proper calibration templates for you. Not agressive,but basic just so it would be noticeable,but properly done and calculated. Won't recommend file services,because most of these are just money grabbers selling % tunes. And you will need many of those,because for example even tho the ECU's and engines could be almost identical the values inside maps are different. For example EDC15 PD engines: AWX and AVF. Same ECU's,same engines,but values in almost all maps are different even tho they both are 130HP. ASZ also is 130HP,but has same flow injectors as ARL engine(550cc). Same goes with other ECU's and makes. Same thing goes to other ECU's and makes. Engines could be same,but hardware around it could be different(same thing inside ECU file). Some of cars has almost identical engines,but are detuned from factory. They have 2 or 3 of same emgine versions,but are detuned inside the file. So you can have similar power figures from detuned from factory engine and slightly more powerful version. So you can't just put one template on same ECU's and engine types.
