I was trying to tune Mivec on AEM EMS for a long time, but everything i can do with, is ruin my idle. My setting now ist better as turned off, but milles away from my setting with OEM ECU. I think the biggest trouble on AEM EMS is, it is too complex, but absolutly without support or correct base map. Any other ECU builder, like Motec, Haltech, Apex will give you start map that works even or better than a stock ecu, just AEM gives you sh*t that is nearly impossible to even turn engine on. You need to tune all the corrections, transiotions and parameters yourself. And if you dont have 20years of tuning behind you, you will never tune it to nearly perfect condition.
I have perfect:
millage, off-boost response, launch control, powershifts, air temperature correction, mid load response and power
I am sic on:
Starts (poor sync), accel fuel, response after each shift at high boost run, turbo response at all, mivec tuning, stable idle - but no power to hold it (like lack of mass on flywheel?)
AEM EMS is more than one year in my EVO9 and i am still changing here and there, its better and better, but still not perfect for me. I was able to do better allaround setting on Haltech in 4hours then on AEM after one year!
AEM EMS is simply too complex and unsupported from manufacturer. For example you have aproximatly 30 graphs and 49 parameters just for fuel !!! Ho can be able to find optimal mix off all this tables and paramters for perfect setting ? OEM ECUs are tuning on different teams, on different places on earth for veeeeery long time to be nearly perfect in every condition, and if you buy EMS you need to do it yourself.
You can say : Just call an pro. But even pro cant solve problems like very slow recovering from ALS mode etc.... because there are too many trouble in ECU code itselfs, not just in setting.
We can try to build community, and help us each other, or buy another ecu.
ANd for the MIVEC....... VVC#2 Duty table looks very unrealistic for me, try to focus on it.
