    Weird Low Idle Issue

    The throttle body shaft seal is located above the MAP sensor so that leak won’t affect trims like one downstream from the MAP. A base gasket leak certainly will. To narrow it down, disconnect the HVAC vacuum line, EGR solenoid line, and brake booster line at the manifold and plug them. You get...

    Tuning DFCO for better engine braking and fuel economy

    I’m interested to see Skylines’ tps voltage at closed throttle and IAC count. He may need to open the throttle blade because the IAC can’t keep up.

    Tuning DFCO for better engine braking and fuel economy

    Is this with the throttle decay rates lowered or stock? Did the hang occur with a completely stock tune?

    Dana 35 Pinion Seal Replacement

    Just to close out this thread, everyone’s instinct was spot on and the advice was solid. I had the opportunity to speak with Tom Woods Shafts so I asked them as well. Their advice and apparently a fairly common practice is torque to 160ft-lbs and red loctite the nut. Thanks again everyone.

    Tuning DFCO for better engine braking and fuel economy

    You are correct on the decay rate. The values are increments or steps of adjustment. Small number = small steps. I mentioned in another thread idle rpm and timing. I still think there might be something here. If decreasing your vss idle spark threshold to 8mph raised the hang rpm, it may...

    Dana 35 Pinion Seal Replacement

    Thanks for the sanity check everyone. I think I’m going to get a new nut, gradually torque it while checking rotational drag. Hopefully get it to 160-180# with loctite. I’ll keep and eye on it and redo the crush sleeve after the holidays.

    Dana 35 Pinion Seal Replacement

    I hate the thought of arbitrarily increasing the torque on the pinion nut, but I don’t feel this is correct and it sounds like you all agree. Thinking out loud, I could measure the current rotational force as assembled at the pinion nut and incrementally increase the torque setting until a...

    Dana 35 Pinion Seal Replacement

    I haven’t increased the torque and tried, although if it does drastically increase the rotational force required, I’m cooked at that point because there’s no going back.

    Dana 35 Pinion Seal Replacement

    The plan is to apply loctite to the nut on final assembly but again I was put off by the low torque on the nut so I haven’t completed the job. I agree that the figure sounds way low but there was no issues with the axle that would indicate a problem with preload/bearings. I was apprehensive...

    Dana 35 Pinion Seal Replacement

    I recently pickup up another TJ with a weeping pinion seal on the dana 35, so I decided to through a $10 seal at it. Full disclosure, I know I'm taking a short cut here by replacing the seal without replacing the crush washer, but I'm trying to preserve a newly paved driveway and I don't have...

    Tuning DFCO for better engine braking and fuel economy

    Yeah my bad - I guess I misunderstood. I never learned emoji etiquette. I was too busy yelling at neighborhood kids to stay off my lawn!

    Why this response? I was giving him a compliment and appreciated his sharing. Other forums are nearly as open.

    Nice work!!! It’s good see more people tuning and sharing especially because the dodge community is pretty tight lipped.

    Weird Low Idle Issue

    As a tangent to the thread, you mentioned you have your idle at 824rpm and you sometimes have a hang. If you look at your timing table, there is a plateau in the idle areas from probably 500 up to roughly 800rpm where it then jumps up considerably. The pcm uses timing to control idle speed and...

    Weird Low Idle Issue

    At rolling speeds above 2mph the pcm is adding to your target idle speed which is why you don’t experience the problem during a slow roll. It also adds rpm for a period after cold starts and when the AC is on, again masking the problem. Just for good measure, After you replaced your IAC, did...
