Hi, I am new here. Just purchased a 2016 FiST, 1 owner with 35K miles. It is very well taken care of and has the following mods:
- Mountune intake plumbing, intake, and intercooler
- Cobb motor mount
- Cobb catback exhaust

Now, I bought it from a dealer as it was a trade in; however, I do not have the owner's information. My question is... I would like to identify which tune I have and possibly know the maps (if they are standard for a particular tuner). It has 4 maps: Map 1 and 2 are almost identical in quickness, Map 3 is clearly economy mode, and Map 4 seems the fastest.

Does this sound similar to anyone else that has a tuned FiST?

Thanks in advance!! :cool:

Do you have an Cobb ap3? If so look at the Maps and the Tuners usually label their stuff accordingly to stand out as their TUNE*
I don't have the Access Port, but guessing it was a Cobb. Only thing I have to go by is the 4 maps when hitting cruise control button,

You will need to contact Cobb And get an AP3. Until then I wouldn't go into the aggressive tune until you know what Tune/MAP it is. You could contact Westley @ Phul performance also and go illuminati Instead of Cobb too* Its like $170 for the Software/Tuning device that plugs into the OB2 port.

Yeah the fast one or your map 4 might be a ethanol map. If you're not mixing e85 in your tank the engine might grenade. You might have a 91 octane 93 octane eco mode and e30 maps. You're playing with fire man.

Thanks for the feedback gang. Yeah I only switched them temporarily to see the differences, left it on 2 since I am running 93. Car is fine and hopefully get a call from original owner this weekend🤞🏼
