SpeedDensity - AFRs jumping
Hi,
I`ve got a Problem with my SD Convert too.
I`m on 96531706 Tephra, EDM Ecu with Spoolinup Harness.
first Startup was no Problem but the car was very lean in idle.
I increased the "SD RPM VE" table, from 100 too 145 to get my AFRs in a good Region.
(is 145 normal?)
but my AFRs are jumping from 14 to 16. not very stable.
also if i open the throttle it does not feel very smooth.
any idea what could be the Problem?
my log:

I started with a cold engine, but on the last log the oil was already at 60°C and water was already warmed up.
But the tables I adjust to tune stft and ltft is still the rpm ve table? I ask because I'm at steady throttle openings and the afr is jumping.

That's what I was thinking but just wanted to make sure. You have something inputted wrong somewhere then. You setup for OMNI 4 BAR or whatever you're using right? You should have started rich and safe around 100 RPM VE and had to lower it to get AFR in check.
