Map 3 or 4?

[MasonK]

Hey guys! I’ve tried finding the right thread but can’t find anything exact. I moved down to the Houston area where I now have access to E85 (been getting it at the Kroger) so it’s minimum grade is E75. I’ve been running map 3 so a E30 93 oct blend with zero problems. My question is would map 4 be a safe option with the gas blend of good E85 like I mentioned and 93oct?
Btw I have the BMS package so the proper plugs, intakes Ect!
I’ve been enjoying map 3 but always wanting more power so if map 4 is a safe option lmk

The only way to tell is if you post a log. There isn't a yes or no when it comes to selecting maps, it's up to the car.

The answer I was expecting haha
When I get a chance I’ll try to post some of map 3 and then map 4. Wish I knew how to read them so I didn’t have to inconvenience others.

Ensure you attach the csv file. You can view your log on the built in graph in the app, it's quite easy. All we are looking for are timing deviations, or knock.

I only have intake and plugs and I'm running map 5 on e30. For me, map 4 felt slower/weaker than map 3 (I still don't know why).

How do you check for knock?

How do you check for knock?

Changes in Ign_1 which is (absolute) timing advance, and high values in Ign_2 through _5 which is relative timing pull vs. Ign_1. The former is easier to see in graph form because it's obvious whether timing is building as expected, and where the dips due to gear shifts (which are expected) occur. The latter are easier to see in spreadsheet form.

This post has a link to Burger's guide to reading logs, as well as my amateur attempt at explaining:

Wondering if anyone could let me know if I am running at a safe level I have no idea. What my air fuel ratio should be. Please help someone.

I’ve had my JB4 for a while now just installing it what a difference it makes I’m only a little concerned that I am not really able to read the logs do you know if I am running in a safe range love how fast it is but I really don’t want to hurt my car
