    That was the issue! Thank you for the answer. I think v8.4.67

    LLY $0595

    For my 04.5 LLY, I wrote up a tune for my truck, modifying the OS file I have loaded on it now. When I went to flash the new tune it gave me error $0595 about firmware compatibility on the handheld during the flash. Any idea about why I can’t flash it anymore?

    Base Torque tuning

    Delayed response, I apologize. Thank you a ton for the information. I was unaware of the TCM table. This all is super helpful in understanding those tables. I still haven’t gotten around to finishing my tune yet. I decided between life and the truck, getting all the mechanical inconsistencies...

    Base Torque tuning

    Hi all, I have slowly started to create a tune for my LLY. I bought the starlight diesel book a while back as a intro to tuning, which has been helpful. I want to create a tune and add about 60?HP to my truck. I’m having a hard time wrapping my mind around the torque tuning, specifically the...

    Erratic shifting

    As far I remember that’s the only code that came up, which was for the pressure switch. I don’t remember the TCM code, but that was the only code. My father in law cleared it and it never came back, but my shifting is harsh, and in OD if I’m going 80+, I have plenty of passing power. At 60 it...

    Erratic shifting

    My truck is outputting some erratic shifting. Filters are good, at one point I had a P0700 and the code read for the pressure switch. Cleared the code and it hasn’t returned. A while ago I had a cooler line fail and it dumped the fluid twice. Sometimes it shifts fine, usually when starting and...

    05 LLY Baro wiring diagram

    Would you also happen to have the pin outs for ECM J1, J2, and J3?

    05 LLY Baro wiring diagram

    Does anyone have a 05 LLY wiring diagram for the barometric sensor? I’m getting P2226, P2227, and P2228

    Intermittent dash electronic issues

    Hey all, I purchased EFI live and shortly after using it (with successful flash) the OBD port starts intermittently losing power. The Flashscan will power down and restart. It’s not the cord to the unit. Following that my engine hours reset to 0, and following that my radio reset to default. The...

    Normal FPR duty cycle?

    Ah ok, thank you for the heads up. It seems like whatever is driving the ECM to control the pressures is part of the problem. I checked my balance rates again today, and they are not too great. Checked compression on #5 and #6 again with a new compression tester, and tested 390 and 400...

    Normal FPR duty cycle?

    Thank you for this!! Very helpful. I believe the sensor in the junction block may be my problem. Any idea as to what sensor that is?

    Normal FPR duty cycle?

    Thank you for that! I appreciate the information. Also, I ran a diag procedure off of the P0089 pdf you posted and my rail pressure sensor reads 180 MPa unplugged, so according to the diag step 7 I need to replace the rail sensor? I did skip step 6 because i didn’t have a computer handy at the...

    Normal FPR duty cycle?

    I could be wrong, but I believe the FPR regulates fuel via adding voltage to restrict fuel, and that is why it goes to max pressure when the power is disconnected. I have this CP3, about two years old...

    Normal FPR duty cycle?

    I was doing some data logging the other day and I noticed a few things. My desired pedal position and actual match pretty closely, and my fuel pressure desired and actual are within 2MPa of each other, but my FPR duty cycle is always 20-40% throughout the RPM range. Is this normal? I’ve also...

    Fuel injector knock

    @2004LB7 would you happen to have these diagrams for the 04-05? Thank you again

    Good compression - Bad balance rate

    Here’s a report so far: Checked the Injector 1, 4, 5, and 6 control circuits and am getting 12.1V to the FICM key on engine off. Also tested resistance and am seeing 0.00.

    Good compression - Bad balance rate

    Does anyone know of a way to get a part number for the pins themselves for c107/c108 and its counter parts on the other harness?

    Good compression - Bad balance rate

    As far as I understand the cylinder power output is low, and the ECM is trying to add fuel to that cylinder to compensate for the imbalance in the engine cycle. OR I suppose other cylinders could be causing the ECM to try to compensate for them. Edit: also, the balance rate is subject to the...

    Good compression - Bad balance rate

    I hope you’re right. I had issues getting it plugged back in. The weatherpak insulator seemed to slide back and the connector wouldn’t connect easily. Seems like the inside of the connector had some sort of residue in it. I cleaned with QD. I guess this might coincide with the suspected FICM...
