    There's quite a few torque limiters and airflow tables that could benefit the HPT files by being added to the cal definitions.

    Usually the different modes are for 1 or more of the following . Sometimes there are more modes than are actually used.

    Part throttle closed loop
    Part throttle open loop
    Catalyst heat up
    Regen
    SCR De-soot
    Derate/safety

    And if anyone from HPT can chime in are some of the Channels that do not work eventually going to be sorted out? In particular WB EQ ratio, or at least a Commanded Eq ratio from the truck to reference a aftermarket WB gauge against. And MAF frequency, or in this case microseconds
    I'll see about adding a channel for the Mode.

But throttle response was not fixed until I did the EGR trick. I did this, and drove around for 200 miles. The truck was definitely quicker and more fun to drive than the base tune with no EGR. I loved it, but there was one problem- when in cruise control, the truck would hold on to lower gears for far too long, thus killing MPGs. This was the case from 55-75 mph.
    I'm sure there is a fix for that, but I don't have the time and I won't buy 4 more credits to license the TCM and find out. The base AEM tune with no EGR fixes throttle response, which is all I really needed ( I don't have enough miles on the base tune with no EGR to give MPG results). If someone would like to give my GDE based tune a try, here it is (over 200 miles, there was maybe 1 MPG improvement in my case, but most of it was not in cruise control to help the MPG situation).

    Side note, HP Tuners support says my GDE tune is the reason I can't read my Grand Cherokee. I'm not sure why others have been able to read GDE tuned vehicles. So as not to confuse anyone, I have an ecodiesel Ram I left stock and a GDE tuned GC.
    I have a stock 15' GC with the AEM completed (it does the coughing thing), I'm going to try the EGR trick first but i have been staging a file based off your attached file "Base Tune with GDE Calibrations No EGR". After i get the No EGR piece working right i wanted to play with these calibrations. Just wanted to confirm this is the GDE hot tune for a RAM? I'm seeing a lot of different perimeters when comparing files. I currently have a Ram with a PPEI 60HP tune GDE hot tune equivalent. I can use the Ram to compare afterwards, in theory the Jeep should be faster due to the AWD trans compared to the 4x4 with the Ram. Which brings me to my next point, are the tunes the same for both styles transmission/vehicles cause looking at them from the TCM it's a completely different animal. I just don't have anything to compare it with. It would be awesome to see what your tuned Jeep file would looked like.

    Update: EGR trick worked thx LTstewy8 no more hesitation. I'm going to try the GDE calibrations and let you know how it works out. I'm also going to try to read my truck and compare just for curiosity. If you do get the GC file let me know i'd like to see if there are truly any difference between the two files.

    Hey can someone clarify on this. The other day i did some WOT pulls, just trying to see what map and mode is being used in that condition. To me it looks like Map 2 Mode 0 is the normal map being used. However, while comparing my Fuel Timing for the Main Injection, Nothing comes close to the Timing in the map VS the timing I am reading in the scanner. BUT if you follow the timing and maximum TQ which is 663 ft/Lbs on Map2 Mode 0. Under WOT the scanner and the and the file at 663 ft/lbs seem pretty much dang spot on? Anyone one else feel this way? OR am i doing something wrong. And yes i know its Logging Trans Engine TQ, but thats the only channel that gives your a TQ value that you can plot against in the calibration files.Attachment 98400Attachment 98401Attachment 98402

    And obviously on the scanner it wont show a value in 663 ft/Lbs while logging in the chart. What i was doing was just comparing different spots in the RPM row. Flipping back and fourth between Scanner and Editor, So at 2000 RPM im at 10, 2500 im at 13, and so on... To me my INJ timing is right on target, just in the totally wrong column.
    I have yet to license the truck and make a change yet, but i do plan on making the 663 column a fixed number and see if what im thinking is correct

    Thank you, I've been watching the Beta updates like a hawk updating all the time hoping I see something new lol. One more thing if you could also add a channel for Exhaust Manifold Pressure that would be greatly appreciated.

    Sure, I should be able to add that... anymore requests while I am adding?

    Actual and Demanded Engine TQ values that display a TQ value and not a % Ratio please. So I can Plot the Various tables that use a Tq reference.

    Thank You

    So is this GDE tune for an emissions intact truck? And if so, how does unplugging the egr get along with the rest of the emissions systems?
    I had someone ask about tuning one of these with emissions on and was thinking the GDE tune might be a good place to start.

    The initial GDE tune I grabbed the mapping from was a full delete truck, I believe. My own truck is still untouched other than the EGR delete, and ran with no issues using the GDE mapping for a few hundred miles (not a long time). I've been using the AEM mapping with EGR delete for around 1,000 miles with no issues, and I don't expect to have any because the EGR shoudn't negatively affect the DPF or DEF systems.
    When I reflash, I will sometimes get a transmission DTC (Loss of communication with ECM, or something like that) that pops up around 5 miles after reflashing the truck. It throws the truck into limp mode until it is cleared. I just disabled that DTC, as well, since I have reflashed a lot of times, and that solves all issues. I'm not worried about it, because if the transmission controller ACTUALLY were to lose communication with the ECM, I'm pretty sure I would notice without needing a DTC.

    I was also incorrect about only GDE being able to change axis values. HP Tuners has that ability, and you can therefore copy the GDE maps exactly. Just double click the underlined axis value to modify it.

    Are you guys planning on supporting the 2020 ecodiesels? And would/could the new 2020 3.0L Ecodiesel Wrangler be rolled into that group? I'm currently still waiting on my 2020 JL Wrangler diesel that was ordered 5 months ago, but I'm pretty excited about the possibility of utilizing an HPtuner to help patch some issues in the factory tune. Like many others when my EGR fails I'd love the ability to turn it off or to be able to at least disable the associated codes as someone else mentioned.

    I went back and looked at the GDE tune I posted again, and am more confident that that tune should not be used as is on a vehicle with DPF. This is primarily because of the post injection tables. Long story short: less post injection will increase soot at low loads.

    This file is for the Russian market too. The owner of the car claims that he has cut out egr. But what is it?
