    Take a look at my Datalog Please!

    Hey everyone, I'm working on my tune and trying to get it dialed in. I've created this one from scratch and looking for another set of eyes to check my datalogs to see what adjustments need to be made. I can send my .bin if needed. I'm using 93oct pump, only mods are custom DCI's, 3" charge pipe and Tial bov.
    I'm noticing my fuel trims are a bit different between banks and shooting pretty high between 3k-4.5k, I'm thinking I need to adjust my scalar to add fuel in that range? I use a 3D scalar and it's at 1.08 at 3k and 3300 at 180 load, and 1.05 at 4k. Any input would be greatly appreciated!! Thanks!

    I'm by no means an expert tuner, so take my advice with a grain of salt, but what I'd suggest is to adjust your logging parameters. Turn on timing correction logging for all 6 cylinders as well as lambda for bank 2, and you can probably turn off both of the MAF request parameters as well as torque actual value. I also like to log rail pressure to make sure the HPFP is happy.

    Without timing corrections logged on all cylinders it's hard to tell if the car is happy or not, it could be correcting on any of the other 5 cylinders without us knowing. You could probably also run a little leaner, it looks like you're targeting 11.3:1, I run leaner than that even on $#@!ty California 91 octane. Worry about that for the next revision though, for now I'd make the fuel scalar adjustments you mentioned, and go out and take a few more logs with the correct parameters. See if you can start your logs in 3rd gear as well.

    It's not that. People just hate 'look at my log' requests because they happen literally every other day. Most members here expect you to be able to analyze your own logs.

    Don't feel bad, eventually someone will get to it. Just as @nahor did above (repped for effort). It just starts to feel like a chore after you see the 13501850380180'th look at my log thread.

    I'm also not an expert but I'm willing to take a look too.
    As @nahor said, you may want to change your logging parameters.
    - log timing corrections for cyls 1-6 and actual timing for at least 1 cyl ( I have 1 and 6 logged)
    - need both lpfp and hpfp values
    - keep maf req wgdc
    - add wgdc base and wgdc after pid to log
    - I don't log tq limiter/actual. Since you're auto that may be useful
    - here's the what I log datazap ----- u/m6keharr/walbro-e70?log=0&data=3-23

    Here's my take from the limited data in the initial log you posted:
    - I wouldn't worry about the bank variance with stft as it looks minimal.
    - Trims do look high for the that amount of boost on 93. Revisit when you get the hpfp logged
    - You have some Throttle closure mid pull at load overshoot.

    Change your parameters and a post a nice 3rd gear log

    Okay, thanks for the help guys. I'll change the parameters and do a couple more logs once the roads clear up. Everything is covered in ice and salt right now. I didn't know these engines would do timing correction on individual cylinders, I thought if the DME was pulling timing it would pull evenly across all cylinders... Learned something new! Thanks for the input!
