Hi, I'm working on something interesting, and I'd like to get input on the capture I took tonight. Does everything seem acceptable in this log?

not super bad but maf scaling should be a bit better than what u currently have, and you should be able also to raise more ignition timings

I decided to teach myself reverse engineering by picking up the S10C-series ROM and mapping it out in Ghidra. I was delayed a year, but I've nearly finished a working RomRaider XML for it, and the Tactrix config as well.

After that, I plan to do V00C00G to see what changed from 2019 to 2020, because I'm super curious about that. (I own a 2019.)

So the log is of a stock S10C 2019 with no tuning, which was a milestone of sorts for myself

sorry if this is in the wrong place but I'm trying to figure out if I have a fueling or tune issue. Currently my LTFT is hitting -17ish which tells me I'm looking at a fuel leak but when it's happening is during overrrun and I'm not seeing any stft to indicate that it's actually trying to do anything to adjust the fueling (which from my understanding should be near 0) I'm concerned that I may have a leaky injector but my car also had a tune when I bought it and even though it's not the burbliest there's definitely some pops and bangs. I have no idea how to read these data logs for any issues since my experience comes from when we had to literally flash EEPROMs with a flashing light to retune on 80s muscle cars. I would love to get into tuning the twins but I want to make sure my car won't blow up first. Could somebody please look into this and see if it there is any information I can use to further troubleshooting? Also, I'm sorry it appears i clicked the wrong MAP PID so it logged an unavailable one. Here's a torque datalog I made in the mountains today

npothing wrong to me, apart from a maf scaling not dialed in pretty good
i wouldn t mind that negative ltft during overrun when injectors are actually off

New to this forum and OFT. Got a 2013 FRS. Just installed Tomei catless UEL headers, Catback exhaust, flashed OFT stage 2+ tune, Mishimoto CAI. I'm on the fence about the CAI after reading about them not doing any good.
Can you fine fellows take a look at the attached logs and let me know if I need to scale the MAF? If its not doing any harm, I'll leave it in place as is. If it's causing problems, I'll either put the OEM intake back on or attempt MAF scaling.
Any other advice? I'm all ears.
