    2014 Jeep SRT* Whipple

    I am tuning a 2014 Jeep SRT8 with a whipple supercharger. I had previously tuned this jeep with no problems. The motor broke as most boosted Mopars eventually do. We rebuild the motor with a few more cubic inches and upgraded the blower to the gen 3 whipple. I am getting a strange Throttle torque source and it is LV2 and it is closing the throttle. I opened a ticket and was tole this is meant Level 2 limiter and may be a throttle problem. The throttle has had no changes and I thought it may be stock trans tune limiting torque. I liscensed the trans and now I have P1DD2 and U0402. I emailed support and was told this is a tuning problem ask on the forum. I have taken the ecu off the neural network as the cam was changed to a hellcat cam. After coming off the neural network I have start up problems as it has very little after start fuel. After it runs for a min it stabilizes and the fuel trims are small. Thanks in Advance!

    Thanks, any clue what the LV2 throttle torque source means or is caused by. I have the other problems under control. HP support told me it means level 2 but that means nothing to me.

    Just a thought ,I had a sim problem with large throttle reductions between shifts , at the time it was with Neural net disabled
    I remember disabling all the communications under TQ management/ general from enable to disable and the behaviour stopped
    Might help

    I'm guessing he's figured it out by now. Can't remember what I did on a Whipple Charger once but I wasn't getting throttle all the way open because of it. You wouldn't expect it either it was maxing some limiter it wasn't happy about or something like that

    OP, did you ever figure this out? I am having this same issue at 3800 RPM (LV2 Tq Reduction) with a TVS 2650 Hellcat with a Kong 113mm throttle body. Car was great before the blower and 113mm TB.
