Procede 4/23 Agressive Maps

Can someone please clear this up for me. Are the maps:

Map 0 is stock boost
Map 1 is aggressive
Map 2 is Meth map with more boost and timing advance
Map 3 is naturally aspired
Map 4 is meth with fail safe which runs map 1 until meth target is reached then switches to map 2.

or

Map 0-Valet
Map 1-performance
Map 2-high performance
Map 3-NA (turbos shut off)

Thanks!

Got it Shiv, thanks, for those wondering here was Shiv's answer: yes, just run map1 or map2 (they will be the same unless you adjust one to be different than the other). Map0 is stock, map3 is NA (no turbo) and map4 will be unaccessible to you until you install PWM meth

Map 1 and Map 2 are the same? thought Map 2 was more aggressive and made specifically for meth?

Thats' what people said in my other hated thread also but not what I heard from Robert last week so wanted to double check to be sure.

Maybe I just actually added some value to this forum

I've heard couple different things and was always recommended to run Map 1 because Map 2 was the meth map without a failsafe and should never really be ran.

I'm just going to run map 1, it's a great map

I think OTS the user adjustable for boost is the same, is what was implied there. Map 2 contains advanced ignition though, and should be used with meth in Map 4. Theres no real need to ever run map 2 unless you're using a different gas or something that merits its own dedicated map.

For most users on this form, Map 2 switches from Map 1 only when you're in Map 4, and it detects a specified Meth DC.

With the default settings, map1 and map2 are exactly the same in every way (boost, fuel, timing, etc ). You can see this reflected in their user adjustable settings with are the same. Those running methanol are instructed to make map2 settings more aggressive (raises boost % and reduce ignition correction %. So with the default settings, driving on either map1 or map2 will result in the exact same performance.

Historically, folks would set Map 1 more conservative (lower boost) than Map 2. This way they could drive around mostly on Map 1, and switch to Map 2 on the fly when needed.

was switching between Map 1 and Map 2 the other day just to see if they did feel the same and I swear the butt dyno always said Map 2 would pull harder...


upon inspecting the two maps in the interface, the Ignition Advance Tables look different.







I'm not completely sure but shouldn't Map 2 which looks to be more aggressive timing curve be faster than map 1 even though boost is the same?

Ignition correction transitionals have different logic with the agressive maps. For the map 2 Ign Correction value, old style used to be 100% = map1 values, 0% stock values. Now its 100% = map 1 values, 0% = map2 values.

Any percent inbetween is the linear difference between the two maps, applied to the more conservative map. Similar to boost targeting.

sorry, you kind of lost me lol not sure what exactly these values are doing but basically I guess I'm asking if the maps are indeed the same or is one more aggressive than the other?
