I will post up screen shots tonight if that helps? it would help with my descriptions as it will show what the scales are and the adjustment points. There is more in the EMU than i would ever use.
1. Does it handle ignition retard and cut for auto?
Yes
2. Is there a limit to the injector size?
Blue version yes, but i have not found a point on the EMU that is too large ie running 850's on sr's and 720cc's on 26's etc are no stress, i have just done a 2jz with 1000cc but it is not turn key yet, it will be a good test expected 500-680rwkw
3. What parts of the standard ECU control does it leave untouched?
i will have to sit down and ponder that for a while because the more i play the more i find.
4. Does it have a boost control option?
No... soonish i hear full colour lcd possibility.
5. Does it allow for inlet air temp compensation?
Yes There is a inlet temp correction map
6. How is the cold start and run tuning?
Yes There is a water temp correction map
7. Anything else that you can think of that you would like it to have or that a Power FC has?
i use the data sampling option a fair bit which allows you to log the afm's then cut and paste these values into the airflow output map, this then allows you to remove the afm and fine tune via your normal process.
It has a timing offset set function for the datalogger.
its also has a speed correction map also.
launch control that actually works unlike my datalogit system lol but i built my bridge years ago
