    I don't think trying to flash with the key off could cause an issue like that. I don't editor would progress beyond telling you no vehicle power was detected.

  4. Spark TQ Ratio Settings can Affect Fuel Source

    Just wanted to share some interesting behavior.

    I was trying to limit the amount of spark retard after a quick pedal blip while idling (goes to ~ 12* ATDC)

    It seemed obvious to use the Spark TQ...

    My current theory is that this behavior is caused/governed by a table we can't yet access.

    The presence of a table which added frictional compensation based on ERT or ECT would explain this huge...

    Which 3 parameters?

    If someone installed bigger injectors without changing the injector data, then "fixed" fueling with the MAF transfer function, that would cause scaling issues.

    The IAT wiring sounds like "normal" practice for people running a supercharger with a strategy that doesn't support the MCT switch.

    You just send the IAT2 (manifold) sensor data to the MAF...

    If we can rescale axis values on the Copperhead, why would you...

    No, transient fuel gains will not cause a delay in getting to a "power enrichment" commanded EQ ratio.

    No, not really.

    You can define the load:TQ:rpm relationship however you want, but you can't change the PCM's indicated TQ. So if you change TQ tables in a way that doesn't match the PCM's...

    Can you qualify this statement?

    Where in the tune can you directly control the calculated load / air load, on a Copperhead PCM?

    I do and mine is also zeroed.

    I still think DD TQ control could be causing the spark dip.

    The spark dip could just be circumstantial, and not the cause of the giant "desired load" spike.

    I have done everything in my power to disable that mode, but it still shows up. Again, hoping for some fixes in the upcoming update.

    Yeah, this seems like a huge miscalculation.

    Temp doesn't seem to drive it so much as engine runtime < 1 min. It did it again to my today at an ECT of 168*F

    Good eye, but I think in this case the ETC angle error is a result of this bizarre spike in desired load / MAF, not the cause of it.

    In similar conditions (ETC vacuum, effective area, ETC angle,...

    Occasional Parking Lot "Buck" After Startup

    I have an occasional issue that is hard to reproduce, but I got a good log of it today.

    It seems to happen when the car has been running less than a minute, and generally when it is warm to hot. I...

    I'm wondering if the "opening" and "closing" settings are functional. You physically can't change opening without changing closing, so why would they be discrete settings?

    So you think that as long as your VCT mode stays OP, the Load at WOT table isn't changing the MP weighting.

    You think MP7 steals weight simply because the angles near 5000 rpm are close to the OP...
