    Newbie to the cummins world

    If I had an automatic I would just go with a fully built tranny which I’m guessing is what they are calling their race transmission but select a properly suited torque converter and valve body setup. Talk with other reputable vendors as well to get better ideas and cost like Goerend or smartyresources counterpart, source automotive. I believe Redline Diesel Power out of Ohio has good reputation on the transmissions they build as well.

    NADP has good warranty on their transmissions. Depending on the application you intend for your truck, such as towing, may not want to go with a full out race transmission. Your torque converter stall speed wouldn’t be proper for towing applications or daily driving. A full built transmission is definitely a good place to start but go with a transmission built for your intended application of the truck. If you decide down the road to upgrade fuel components like injection pump and injectors, NADP uses Industrial Injection, don’t let them sell you on Industrial Injection.

    5.9L with 6.7L injectors idling

    Here's a latest tune sample with a warm startup datalog and a test run on the current log. Will be able to see in the current warm start up datalog the actual rail pressure is a smoother transition down as it settles once the engine catches in comparison to the screenshot of a previous warm start up up above. Rail pressure when driving follows the desired rail pressure like a dream. Only about a +/- 300psi difference! Previous shutdowns with the fuel rail plug I would get 180mPa spikes, have it reduced to about 150mPa! Rail pressure during cranking doesn't seem to be controllable, so cranking timing needs to be played to find a happy spot where it's not too little and not too much during cranking for when it gets its spike to +9000psi when the engine starts to catch. 85G761083_008_sample.sty Current_Tune_Test_Run.dlg Current Warm Start Up.dlg

    want less smoke

    The smarty shouldn’t be very smokey under normal driving habits on the revo tunes. Something is throwing things off.

    Injector Voltage Ratings?

    Anyone know the voltage rating capacity of the 6.7 injector and 5.9 injector? I believe the injector drivers work on PWM and I’m assuming peak and hold with the 5.9 peak at approximately 90V and the 6.7 peak at approximately 50V. The 5.9 runs a lower current and the 6.7 runs a higher current. This correct? I’m curious if the injector solenoids for the 6.7 have the insulation to withstand the higher peak voltages the 5.9 ecm puts out and not have insulation breakdown or if they can’t withstand the higher peak voltages and run on borrowed time.

    5.9L with 6.7L injectors idling

    Got a nice smooth startup now, chatter at startup gone and not even a wisp of smoke! I’ll post up some before and after data logs later and a sample of where the tune is currently sitting at.

    Confused about Timing Setting

    Just for clarification, “Default” just means that is the setting Mads Electronics decided to use as the setting applied to the SW when flashing and NOT changing timing settings or rail pressure settings or any other setting. It’s like install software on your computer. You have the default settings the manufacturer picks, but, you have the option of changing those settings.

    Any luck?

    Confused about Timing Setting

    For instance, my old 2005 did well on the S-06 highest TNT SW with rail, timing, torque, etc at max settings when I ran a boxed tune.

    Confused about Timing Setting

    Go with whatever settings you like and what the truck seems to react well with. Not all trucks react the same to the same settings. It all comes down to your personal preference and what your truck likes.

    HP tuners thought

    Curious, anyone ever wonder why people are so adement about highly recommending HP Tuners to people who have no gauges in their truck or tuner and are looking into custom tuning, especially for earlier generation trucks, as I have? I mean, sure, it offers same tables and everything to adjust compared to the touch or mm3. But now you are having to purchase extra gauges and are limited on the gauges you can mount. Some times external gauges do not provide the same readings as the ecm sensors. For example a long time ago I tried out an auto meter rail pressure pillar mount gauge and it was WAY off what a scanner plugged to the obd2 plug showed off the ecm. Then if you want to datalog you must plug your laptop in, it’s not always feasible to be like “Hey, I wanna datalog this climb up this hill in front of me, I better pull over and plug my laptop in.” Then suddenly “Oh crap, I just realized I don’t have my laptop with me. Oh why did I pull over before realizing I don’t have my laptop with me?” Just seems to me there just isn’t the flexibility and options there over touch or mm3 to really make it worthwhile, especially if you don’t have any external gauges yet.

    5.9L with 6.7L injectors idling

    Here's the tune sample. Not much done to it. Idle set at 800rpm, zero'd post quantity, modified main and pilot duration, lowered main timing a bit and modified main and pilot cranking timing. sample.sty

    5.9L with 6.7L injectors idling

    A datalog of a test drive. Very very minimal smoke but a dog under full throttle. Hitting Altitude Derate and it just starts pulling fuel. DL00010.dlg

    5.9L with 6.7L injectors idling

    Here's a datalog screenshot of a startup and idle plus the full datalog. It starts up pretty clean and smooth when coolant temps and ambient air temps are low but if either one is up its more smokey and rough on start up. This is with coolant temps at about 160* and ambient air temp around 57*. You can see at the marker the couple spikes in rail pressure where it catches. This startup wasn't as rough as it can be. Idle is very smooth and clean though. DL00011.dlg
