Just switched to SD - sanity check please
Hey guys,
I've been tuning a long time, but this is my first attempt at SD.
Just switched my USDM Evo IX to SD using Tephra v7 88591715 and I wanted someone to provide a sanity check for me.
Attached are my idle and static 3000rpm logs.
Using Omni 4bar, UEGO wiring into the ECU, and Fuel temp option on 93octane.
LTFT low ~0.5 after 10mins of idling at FOT (full operating temp)
UEGO reading rich at static 3000rpm (12.9-13.2afr)(maybe lower RPM ve?)
Uego logging via EvoScan looks to be about .2 to lean (reads 0.2 higher), so I guess I need to modify the EvoScan formula. I cannot remember if I should modify the formula by adding or subtracting 2% to the formula.
I'm sure I missed something, just ask if you need more info..
Anyway, take a look at the logs, and let me know what you think.

O2 feedback seems to be pulling a lot of fuel. Whats your ROM look like? Have you driven it yet?

I wouldn't mind trying it again, any suggestions?
