Hi guys! I've been comparing two ME7.9.10 maps from two different cars with basically the same engine.
The first car is rated at 120hp and that the second one at 160hp with a slightly longer duration camshaft and a ""bigger""(+3mm) compressor wheel.
The first sw allows for maximum turbo pressure of 0.8 bar, at about 150 load while the second has the capacity to peak at 1.2 bar, at about 180/190 load.
I have never seen such a dramatic difference in the KFZW map, especially in the high load/high rpm areas.
In fact, it occurs to me that in the first version the engineers were so lazy that they tuned only the useful cells and then extrapolated all the rest, resulting in ~18-21 degs at high rpm and mid/high boost which could be destructive if not taken care of while increasing the boost.
Below are the KFZW maps (TOP = 120hp, BOT = 160hp). Note they come from stock files and are correctly defined and triple-checked with IDA.
Also i'm really having an hard time understanding why in both maps there are ATDC cells while building boost considering that some of them are consistently reached even by both stock tunes as confirmed by my logs (especially the ones at ~2000/3000 rpm given the tiny turbo). Also, what the hell is wrong with the 5520 rpm row in the 160hp map??
Are there any pros out there able to enlighten me on these three questions I have?
