Keep in mind the 2.0 ECUs run lower timing than the 1.8s. The higher trims are likely because of the E85, but I wouldn't worry about it.
I'm aware 2.0s run less timing but it isn't climbing much at higher rpm. Also, trims are 'lower' than you'd expect with e85 so I suspect the fuel pressure has been raised.

The ECU is running as much as it wants to run in the scenario because there are no timing corrections. Knowing he has ethanol in the tank, I think it's safe to increase the boost, as long as he only uses the map when he has the current or better mix.

I'm sure he changed your fuel setting as well or your trims would look worse. I'd say you could run more boost but I doubt you want ign1 much lower so it's good. I wouldn't recommend anyone use these without working their way up and adjusting other settings if required.

The short version is that it looks good on your car.

I did change fol to 50. Today it was hotter and the map doesn't feel as good...kinda lazy throttle response...I went back to map 0 for these real hot days...don't really need to floor it now. I would assume when the weather gets cooler, the car will feel even faster. Hesitant to get an intercooler now because of lengthy extended warranty, car only has 14k miles, but looking at a twincooler type because of less hassle.

I did a run with map 3 and map4 and they look good to me.. can someone help confirm?

map3: https://datazap.me/u/yungaxel3/log-1595048796?log=0&data=1-4
map4: https://datazap.me/u/yungaxel3/log-1595048796?log=1&data=1-4

Where do I go from here? Any tips on a map 6?

Thanks!

How does Map 3 feel? Your logs look really good for 91 octane. It looks like Map 3 is a really fun and safe setting for you. If you want to go further, copy the Map 3 "target" values in to the Map 6 cells.

Map 3 pulls so hard! I can't believe I can run that map with ACN91 octane..
Do I just copy the target values over and start incrementing the numbers? Do you know what values to put for 1500-3000?
