    I believe I've seen info in a thread here about a clutch switch input that needs to be addressed.
    I'll try to find it.

    A little update after doing the drive/log/flash/repeat process a bunch of times.
    What seems to be working is ramping up the Throttle Airflow tables right of off idle. This seems to reduce the...

    Granted, I usually over complicate things. :)
    But, this is more than just copying the settings files. I want the same settings data (charts, layouts, gauges, etc) to be used by all devices. So,...

    That was my thinking as well.
    I did screw up the chart I attached to the first post. I mixed data between g/s and lb/hr...DUH!!!
    So, here's a new chart with the correct data, all in lb/h, showing...

    For those not familiar with the setup. Here's a picture of it and a video showing its operation.

  6. Configuring airflow for dual Hellcat throttle bodies

    Ladies and gentlemen,
    I'd love some feedback on figuring out how best to set the tables for my throttle setup. This is a 2006 Chrysler 300c SRT8 using the original PCM.
    Engine is a 6.1 based 398ci...

    I have to thank everyone who participated in this thread. I've really learned a ton, and I hope others can find the information here useful.
    As a few here recommended, I had raised the VE table...

    Good call. I'll give it a try.
    Regarding "min airflow" settings. Do you mean Desired Airflow Minimum or did you mean the lower voltage area of the ETC Throttle Body Airflow table?
    Also, I...

    Well, to everyone who put their money on lack of fuel, you win the pot!
    I ramped up the VE table in lower left corner, raised the entire table by 10%, and then backed down 5%. The idle will need...

    I don't have those on mine. What application is the tune from?

    WOT Spark goes up to 150 kPa, so we're good there. (Pic below)
    I'll bring my idle RPM up, bring the VE up, and see how she rolls.

    I think I'm on board with your line of thinking. I started upping the VE to richen up the fueling overcome the lean out, but then the idle went all to hell. I'd dropped the timing to 14 around the...

    I made an attempt to do some drive testing this weekend. I wasn't even able to do that. This current condition makes it undriveable.
    It acts just like when a carburated setup has either super...

    I'll definitely get some logs on the road, hopefully tonight. And of course, now it decides to start raining. Hopefully I don't "find" another telephone pole. :)

    Everyone, please don't hate me for this.
    I just realized I left something out of my original post that's pretty damn important to this all.

    So, this is a bit experimental. I have a 4/7 & 2/3...

    Most of the videos had my old dual TB setup which used an Ozmo controller to run two DBW in parallel. I had issues with driveability, so I worked on this progressive setup.

    Yes, the primary TB is DBW like stock and a slide type link bar attaches the two with different ratio arms on each

    Hahaha! You're not kidding.
    I'm actually working on a parallel engine harness to run a stand alone EFI alongside the OEM stuff. A nice Megasquirt MS3 Pro of Holley Dominator EFI would do nicely.

    Okedoke, I submit this for review by the masses.
    I'm using two stock Hellcat throttle bodies. I took the OEM numbers from the ETC Throttle Body Airflow table of a stock Hellcat tune.
    Then I...

    That looks pretty normal. For whatever reason, that 86% number seems to always be the max. It bothers me, but many have said that there is no difference in TB airflow from 86% to 100%.
    At idle,...

    Ahhh, dammit. I had that all wrong. Well shit. That means I've got something wrong with my O2's then. Because, they're plugged in.
    I hope I didn't do something stupid like plug my rears back...

    I have it locked into open loop using the Closed Loop Enable - Coolant Temp set to 376 degrees.
    I'm working under the mindset that ironing out everything first while in open loop is best. However,...

    Thanks BOOSTJUNKY! You're a master.
    That makes me feel a lot better. The calculated numbers I got weren't too far off from yours. I didn't think about smoothing for the transition though.

    Good call. I noticed mine has a Trans Maximum Allowable Torque vs Gear where the limit is set at 560 ft/lb in 1st and 2nd while 3rd, 4th, and 5th are at 3687.
    Will this cause issues when I actually...
