First tune/data log.....any advice or input?

chrisf63 · Feb 7, 2016

Hey everyone,

Just tuned my 13 ST3 last night and ran a couple data logs today. Haven't messed with any logging parameters, so I'm sorry if it's not correct. Never used this thing before and still learning the tricks. I am using the Cobb AP3 with the OTS stage 1, 93 octane, latest version (v320). I know a fair amount about engines, but some of this data is way over my head. Could someone take a quick look and verify that nothing seems out of whack? I am running this as my daily driver and would like to have some peace of mind.

Side note, holy hell, I couldn't believe how much that tune woke the car up. Nice job, Cobb! :big smile:

Thanks in advance for the help!

I'm also gonna be logging for the first time ever and could use some coaching.

Is the AP easy to navigate? When it arrives my tuner will give me a list of things to log...Are they easy to access?

Also, how do I get the data from the AP to the remote tuner? Is there a usb port or something?

It is pretty easy to use, it only has 3 buttons. There is an AccessPort program that you can download from Cobb when you register your AP. The program lets you load tunes, download logs and keep the firmware up to date.

Yeah the tune wakes it up a bit. This link says Fiesta however this shows what you should log for modifying your tune.
