hi guys, one of my friends is looking into a s/c for his z4m coupe, he asked me a question that i couldnt answer, so maybe someone on here will know, basically, Ess sends a Generic map for the 445 kit to their approved installers, ess advise this map is not changed from their settings, im asked how the software be perfect for EVERY s/c'd z4m as every car is slightly different right? so how does this generic map ensure perfect air/fuel ratio's, how does it ensure no lean or rich situations are encountered and more importantly can it deal with this situations and adjust as per needed? it was always stressed to me that a live mapped car is always best to ensure a car runs at its best, so i wondered how ESS's generic 445 software allows perfect tuning as ess claim, that was basically the question asked, i genuinely couldnt answer it, i did email ESS but i dont think their understanding what im asking.
