    Running Rough - help?

    Car Setup:
    Stock Block / Heads / Cams
    15G Turbos w/ FMIC
    ID1050x Injectors (Injector Scale 817)
    Walbro 450 lph e85
    Aftermarket FPR @ 50psi
    MSD 8.5mm Superconductor w/ NGK BCR8ES (Made extra careful none of the wires were pinched).
    Timing Belt / Water Pump / Oil Pump / etc.
    MAF-T w/ 3.75" Z06 MAF (was running well before) (Blow Through)
    Running E85...


    Anyways I've adjusted the following tables:
    Injector Scale, Injector Battery Voltage, Coolant Temp Enrichment, MAF Smoothing (VE Table), Wideband Scale, ECU Periphery0 Bits, ECU Periphery1 Chrome Mods (see screenshots).


    LTFT doesn't seem to be updating at all. I've tried letting it idle for a while... I was told to try driving it and made a video below of it. It's running very lean (AFR 17-20 at idle). You can hear the loud popping sounds in the video below, based on the AFR i'd imagine it's misfiring.

    Anything I am overlooking / forgetting?

    Have you checked ignition timing with a light?

    Also, one of your O2 sensors is not reading, that will stop your trims from updating as you're actually running open loop. I have a feeling you need to check your mechanical timing as well again.

    Checking ignition timing is usually not required for the OEM ECU setups, but is required if you're running the CAS system or during the setup process for AEM and the like. I check it just to make sure the numbers I'm logging are the numbers that are actually happening.

    Didn't realize the O2 wasn't reading... I am now looking at my other log ( https://www.dropbox.com/s/wxdomlm3en...42.23.csv?dl=0 ) and now I am noticing it's also having a problem. On a '94 Fed Spec do we know if that's front or rear?

    Since I don't have a timing light, is it acceptable for me to just check the timing on the marks? (like in this video: ) I should have mentioned it's a '94 too.

    Could have also noted I have a Gates belt with a solid tensioner and the timing belt / oil pump / water pump was done by a reputable member that only does 3S work in the area.

    Ignition timing is different than cam timing.
