Thread: 2016 Challenger Hellcat injector data

  1. #21
    Hi, can anyone provide a screenshot or a tune file where the Hellcat injectors are installed and working properly in a 5.7? I have the stock Hellcat tune, I am not sure on all the fields to update as the x or y axis is different. Is everyone interpolating the data or resizing the 5.7 table's to Hellcat tables? I addressed the Inj PW vs Fuel and the Fuel Mass vs Inj PW. I am uncertain of the Injector Pulsewidth Offset as its graduated in different KPA's, do I reset the table's vertical access to Hellcat KPA's or ? I have installed a TVS supercharger on my 2017 Pursuit Charger and running out of fuel! Thank you!!! [email protected]

    Late to the party and I didn't get the data but I got inspired to get some data that works. Here is a tune I came up with which is a factory long block 392, factory cam, with nag1 in a 2014 Rubicon. The pcm os is from a 2012 challenger and the tcm is from a 2012 srt grand cherokee. It all works together pretty well. Then the guy asks to make the vehicle more obnoxious. So a whipple 3.0 goes on it.

    The hellcat injectors are copied from a 2016 hellcat challenger in all parts including fuel temp modification except offset. I came up with a nice offset table that just works. Smooth driving and its nuts when you stab it. So I'll share the file. Hope it helps others. The best part of it is that when you make a VE change, it actually does the real change and not something outer space. So that indicates to me that its really really close.

    good hellcat data.hpt
