    Weird 4th and 5th Gear RPM Limit FIXED!

    As of today's VCM Suite 3.4 build, there is a new parameter added that fixes the weird 4th and 5th gear RPM limit some of you guys have reported.

    The Lower Clip parameter under limit needs to be raised up.

    Great news! I'll be able to test this in the next week or so. Will report back in the thread.

    Ya thanks Eric. I had actually hunted this for a little while since we do a lot of half mile stuff. Found it over the weekend while the guys were in Ocala and was able to test it and it works.

    Awesome! Can't wait to try this out. Had a customer shifting to 5th early last year due to this...

    I wish I didn't have to wait a few more months for the track to open up here. Last year was a frustrating year at the track causing me to lose many races I should have easily won because of it. I'm so psyched to try out Eric's fix for these rpm limit issues. I knew he'd get it figured out

    Has anyone confirmed this fix yet?

    Still have a month or so before tracks open here locally.

    Everyone I have talked to says it fixed their issue so far.

    Can this be added to the 2014 SHO? I'm encountering Engine Speed Limit (Torque Source Error 4) when launching at a high RPM with my SHO.

    I just raised it to my rev limits. This fix is working amazing too. I now have 3 weekends at the track with about 40 passes and not one single phantom RPM limit.

    This parameter isn't available for the SHO EcoBoost, but I haven't tried 3.6 yet. Any word on whether this is available for EcoBoost?

    There hasn't been a report of the Ecoboost vehicles having this problem, but if you suspect this is the cause, let support know.

    I already did but it's been a few months with no word or update. Recall I had an Engine Speed Limit error launching too hard off the line with my SHO.

    Eric,
    I replied to the ticket email with this thread and my original thread on HPTuners, but I noticed I already included this thread in my ticket email from 2 months ago, and I haven't heard back from HPTuners.

    Eric,
    Thank you. I was able to download the beta and change that setting.
