    Question Issue with Rough Idle, 2007 Dodge Ram 5.7

    I have a fully rebuilt 5.7 engine with a CompCams Camshaft #112-300-11 and MDS Delete as the only modifications. Since I have gotten my HPtuner a few weeks ago, I have not gotten the engine to idle properly. I have followed the new to dodge tuning and have gotten the initial idle to be smooth, but after about a minute of idle, the engine turns rough. I thought that I had found the key to fix this in one of the forums that had the barriatric pressure learning set to disabled. This did not fix the issue and it remains.

    Is there something I am missing that is really basic? I am attaching the latest tune and corresponding scan.

    So thank you, the tune got me to get it out of the Garage. I now have a new set of data to use for learning and update the tune since I had a white plum of smoke behind me when I went around the block.

    when you reference bank 1 sensor, is that the O2 sensor bank 1?

    Nice idle and throttle response

    I have a 2005 hemi with a Comp 273 cam you can try this tune outOct 12 Revised Tune.hpt still making adjustments but runs good just a little surging when letting off the throttle around 1100 rpm in gear.
