Hey guys, I hope someone can help me here. I cannot seem to log any data for my fuel trims using evoscan or Mitsulogger. Data shows as 0. My car has been running rich and it must be the scaling. I say this because the scaling right now for my ID2000s is 1125 for e85 which is what shouldve been used as a starting point. Latency looks correct and from my understanding those values can remain the same. I need to see what my trims are which I'm guessing they are off. Idle is around 10..5-11 same as cruise. Sometimes it will correct itself, but its mostly in that range.

Am I missing something in evoscan? or most likely in the ROM? i have the rear o2 simulator on and everything else that I think I need for it to read. I can also uplod my map here if someone would be so nice and double check everything. Thank you!

Sounds like the car is in open loop. Check perifery bit. FAA bit 4.
A 0 is forced open loop. A 1 is normal open closed loop cycles.

Thank you for your response! I forgot to mention that periphery is also set to 1 for normal loop cycles.

I tried disconnecting then reconnecting the battery based off what another thread said then started logging immediately and it still didn't pull any data.

I might try a fresh Tephra v7 map with only the injector values changed to run on e85, but still looking for help.

update:

I used a new tephra v7 ROM and did the bare minimum changes to get it to run on my car, so basically injector latency and scaling. Car fired up no problem, and there it is, evoscan started pulling data for the STFT after each cycle. Crazy part is that the AFR was way more normal than my tune. I swear that tune expired. By no means am I trying to tune the car myself, but now I know something in the ROM is basically preventing me from getting that data. Now to understand what the fuel trims mean.
