Dealer installed my headers and just had to mess with the PCM.. WTF? I need advice!

[srt8_hmi]

Perform RRT 09-073 Flash:driveabilty improvements(my ass)

Perform RRT 09-043 Flash:PEM module(what in the hell is that, PCM?)

I absolutley love the headers, how I've lived without them is beyond me. but the shift points are completly different. It's as if the car falls on it's face between gears. Never did I ask for any of their "improvements". Is this common? Why would they waste their time to do it? The funny thing is that I didn't buy my car their and the service manager has given me tips while at the track I race at. So much for my custom tune, it won't load. My cal code is 68004302ad and isn't supported. It asks if I want to downgrade to "AC" in order to continue. Should I select agree? What does this sh!t mean? All I want is to have it the way it was before the dicked with it. Any advice is appreciated.

if the diablo will actually let you downgrade to your previous calid then it's probably the only way to use your custom tune again.....I would verify it with Diablo first.

Thanks Erik. The whole downgrade thing was news to me.

RRTs are meant to be performed before retail delivery of the vehicle. quite a few of them get missed. chrysler's policy is to check for outstanding RRTs as well as recalls whenever a vehicle comes in the shop and have these performed ASAP. i'm assuming the dealer didn't know you were running a custom tune. i understand your frustration about services being performed without your prior knowledge but chrysler's policy does not take into account modded vehicles and leaves the onus on the customer to advise the dealer about what precautions to take before any repairs are attempted.

not layin' blame here. just trying to explain what may have transpired.

btw, PEM = passive entry module.

So what is the PEM?

I always specify NO COMPUTER FLASHES OF ANY KIND!

Okay.. Let me rephrase. What is the passive entry module? Is that just the door locks and alarm? Lol

[formerice]

Always take the tuner with you when you take it to the dealer and tell them absolutely to tell you before any computer flashes. Then you can at least take it back to stock. Always tell them that you have a Predator tune installed. And , you are right, headers really let a hemi run like a hemi should.

DESCRIPTION



The Passive Entry Module (PEM) (1) is the primary component of the Passive Entry (PE) and Keyless Go (KG) systems. Vehicles not equipped with PE or KG do not have a PEM installed. The PEM contains both the Central Processor Unit (CPU) and transceiver of the PE and KG systems, and is sometimes alternately referred to as the PEKG module or receiver. Concealed within the molded black plastic PEM housing is the printed circuit board and the other electronic circuitry of the module.
The PEM is secured with two screws to the substrate on the back of the instrument panel base trim, above the upper glove box opening near the passenger airbag retainer or chute. Two mounting tabs (2) at opposing corners and two connector receptacles (3) are integral to the PEM housing. The connector receptacles contain all of the terminal pins that connect the PEM to the vehicle electrical system through two dedicated take outs and connectors of the instrument panel wire harness.
There are at least two unique hardware versions of the PEM. These versions are required in order to accommodate the two Controller Area Network (CAN) data bus systems possibly found in Chrysler vehicles, CAN-B or CAN-Interior High Speed (IHS). The PEM used for this platform must be able to communicate with other electronic modules in the vehicle using the CAN-B data bus network.

The PEM cannot be adjusted or repaired and, if damaged or ineffective, it must be replaced. The PEM software is flash programmable.



OPERATION
The microprocessor in the Passive Entry Module (PEM) contains the logic circuits and controls all of the features of the Passive Entry (PE) and Keyless Go (KG) systems. The PEM receives battery voltage on a fused B(+) circuit and is grounded at all times through a hard wired remote ground point. These connections allow the PEM to operate regardless of the ignition switch position and with the IOD fuse removed.
The PEM has sufficient driver outputs to power a number of Low Frequency (LF) Radio Frequency (RF) antennas located within the vehicle, which it uses to communicate with up to eight different FOB with Integrated Key (FOBIK) units that have been programmed to the vehicle. The FOBIK units communicate with the PEM using Very High Frequency (VHF) RF communication on a frequency of 434 MegaHertz (MHz) using digital Frequency-Shift Keying (FSK) modulation, and uses faster data rates for the PE functionality only.
The number of antennas and the specific antenna locations are designed to ensure complete vehicle interior coverage. The LF antennas are each numbered and connected to the PEM on dedicated and sequentially numbered circuits. This arrangement allows the PEM to localize the positions of transmitting FOBIK units using a triangulation strategy.

The location of a valid FOBIK is critical to the PE and KG features that the PEM will allow. The PEM has the ability to distinguish that a FOBIK is inside, outside or within the trunk of the vehicle. Inside of the vehicle is defined as anywhere within the passenger compartment and up to 10 centimeters (4 inches) from the exterior surfaces of the vehicle. Trunk is defined as anywhere within the trunk compartment of the vehicle.
Outside of the vehicle is defined as anywhere within about 10 centimeters (4 inches) and up to about 2 meters (6.5 feet) from the exterior surfaces of the vehicle, but is further differentiated by zones. The PEM identifies the zone in which the valid FOBIK is located as the active zone, which determines which vehicle aperture becomes accessible. The PEM will not respond to an input from a zone that is not active.
When the PEM microprocessor detects a PE input or KG request, the system program logic challenges the FOBIK to identify whether it is a valid key. If a valid key is detected through the response from the FOBIK, then necessary electronic message commands to other electronic modules in the vehicle will be sent by the PEM to enable or disable the vehicle starting system.
The PEM uses On-Board Diagnostics (OBD) and communicates with other modules in the vehicle as well as with a diagnostic scan tool using the Controller Area Network (CAN) data bus. This method of communication is used by the PEM to acquire vehicle configuration data, including customer programmable features. The PEM communicates with the Wireless Ignition Node (WIN) (also known as the Wireless Control Module/WCM or Sentry Key REmote Entry Module/SKREEM), the ElectroMechanical Instrument Cluster (EMIC) (also known as the Cab Compartment Node/CCN), the Powertrain Control Module (PCM) and the Totally Integrated Power Module (TIPM) (also known as the Forward Control Module/FCM) using the CAN data bus.
The PEM microprocessor monitors all of the PE and KG system circuits, then sets active and stored Diagnostic Trouble Codes (DTC) for any monitored system faults it detects. The PEM will also send electronic message requests to the EMIC for the display of certain textual warning messages related to PE and KG system operation in the Electronic Vehicle Information Center (EVIC).
The hard wired inputs and outputs of the PEM may be diagnosed using conventional diagnostic tools and procedures. Refer to the appropriate wiring information. However, conventional diagnostic methods will not prove conclusive in the diagnosis of the PEM electronic controls or the communication between modules and other devices that provide some features of the PE and KG systems. The most reliable, efficient and accurate means to diagnose the PEM or the electronic controls and communication related to PE or KG system operation requires the use of a diagnostic scan tool. Refer to the appropriate diagnostic information.

Thanks for the info. You know way more than I do! So can the driveabiltu improvements falsh effect the torque management?

[WEWSRT8]

Ben Ben Ben! How could you let this happen! Even if I take my car to get an oil change, which is very rarely. I make sure to tell them not to touch my "F'n" computer! I'll send you a text with someones cell number that should be able to help you, my friend.

[srt8_hmi]

Thanks Walt. I just tried texting you about heading to the track today. Only problem is that I'm at work and have no reception! Lol atleast I have wifi on my iPhone.

[WEWSRT8]

I haven't gotten your text yet. What time do you what to go to the track? I plan on going to that meet & greet @ 3.
