  1. Help me build a smooth idle and timing curve

    I think I've basically gotten the gist of dialing my AFR's in my VE table, but I'm still basically working with a pieced together timing curve and my idle timing seems to be super choppy and not...

    Flooding at highway speeds

    For some reason, at highway speed (50 mph+) I get this weird flooding condition at half throttle. My AFR's drop way beyond what I think my fuel map says they should. Is there something in my tune,...

    Gen 3 EFI on non-chevy motor?

    Anyone seen any cases where someone has adapted the Gen 3 EFI to a non-chevy motor?

    I'm just starting some research and knowledge collection for a dream I have.

    Just point me in a direction......

    Looks like it was a combination of burst knock and a conservative timing curve.
    I've been playing with the timing table with RTT a lot lately and this car is really waking up in the lower RPM's.

    What does PE delay mean? Is that 60 seconds of PE use? Or 60 seconds from startup? Or what?

    Here's a new drive log and an adjusted tune. I took all the burst knock out and changed the delta cylinder air to 1.00 g/cyl, I figured this would be enough.
    It seems to be a little more responsive...

    I thought you wanted all fuel trims off while tuning the VE table?
    My WB is in my downpipe, but I do have a major exhaust leak at my v-band inches from my O2 sensor in that bank, so I'm assuming...

    Hmm... For some reason I didn't seem to notice that much knock. Maybe I'm not looking in the right place.

    Is it better to pull timing to eliminate knock altogether, or eliminate knock retard at...

    Why is timing being pulled?

    I'm getting my tune to really good spot... much better then its ever been.
    I just got done doing some wideband VE tuning and the car drives a lot better, but my off idle timing seems to be holding...

    Swapped injectors 3 & 7 with injectors 4 & 6, and still no change to the O2 readings. Bank 1 is still very rich and Bank 2 is very lean. I tried tuning on the STFTs and they were ultimately opposite,...

    Thanks for all the help so far.

    So reading the graphs, Higher mV means more lean, and Lower mV means more rich?

    If so, with the exhaust leak, it should show up much more lean, rather than drastically rich?

    Found a pretty significant exhaust leak at a v-band just a few inches before the bank 2 O2 sensor. Would this cause it to read almost completely opposite what it should?

    What do these O2 sensor readings mean?

    I've been trying to get this thing to idle more comfortably and fixed some issues, but haven't made much progress.
    My bank 2 O2 sensor was reading near dead, so I checked my wiring and found that I...

    What's a good starting point for a fuel ratio under boost?


    Also, I have been wondering what a good (safe) starting point is for timing? Maybe you could shed some light into this for too.

    Where did IAC go? (Scanner)

    I upgraded from an old beta to the new full version and now can't seem to find IAC steps in the scanner. It seems like it doesn't even know there's an iac valve on my motor, as there's no listing in...
