How to Change Chrysler ngc ecu calibration number

[trivilin8]

Hi, I've been needing a lot changing calibration ecu numbers for either jtec or ngc Chrysler ecu's, I have access to either witech or starmobile, and the access to Chrysler website as well from a friend of mine, I have seen two person that have done that but they don't tell anybody, that means It is possible, but all Chrysler technician I have asked, have told me that it is not possible to change the calibration unless the module is virgin or new, I don't say anything but I know it is possible, I don't know if it needs another tool to clear the memory first (make it virgin).

I really appreciate any help, I've been looking anywhere for the ecu and I only have found one with the exact number but it has another calibration that doesn't match the car.
The Car I am stuck now is a 2006 pt cruiser w/o abs and the one I found is 2006 w abs

Thanks in advance

Hello,

I don't have access to witech/starmobile, review my procedure and verify if it could be adapted to your interfaces. I use CarDAQ-Plus as my J2534 reflashing interface. First of all, I download calibration files from Tech Authority for the target car (eg. 2006 PT27 2.4L AUTO 50SW/O ABS), calibration needed would be 05094452AJ (or the one that you need...). You should have 3 files:



05094452aja_05094719aea.efd, this file is the memory image, the calibration itself that will be programmed
05094452aja_05094719aea.flpart, this file is like a configuration file
FMS138.fms, this file is specific for each hardware-type of JTEC, NGC, etc


The trick is edit the configuration file (the second one), you can open it with notepad, it's an XML file:


<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE FlPart SYSTEM "flPart.dtd">
<FlPart>

Replace an OldPart tag with the current calibration that has the NGC, save it and start programming. I have executed this procedure in several SBEC, JTECs, NGC successfully.

Excellent, I don't think it'll be possible with witech or starmobile i have acces because those update the calibration just with a clic, there's no need to download files, but I really appreciate this trick, I've been needing that a lot, I'm gonna buy a pass-thru programmer ASAP to do this, in fact, I don't know if you have had experience with those, but what I have in mind is either Launch j-box or snap-on pass-thru pro II.
Or do you recommend another?

Thanks for the tip, really, I'm glad there's good people in the world.
Thanks

I was just taking a look to car-daq plus and looks really the same, in fact the three j2534 looks exactly the same, I think most be one company that manufactures them to sell them to snap-on, launch and drew tech.

Which is the best ?

[raac]

Hello, as far as I know, Drew Tech manufactures to Bosch Flasher Pro J2534 Programmer (http://www.boschdiagnostics.com/TESTEQUIPMENT/DIAGNOSTICS/J2534/PAGES/J2534FLASHER.ASPX), maybe also manufactures to Snap On and Launch. I know that CarDAQ-Plus has been tested and certified by several OEMs. I'm very glad with their support.

Mike Drew of Drew is part of the SAE J2534 board. He has alot of say in what happens in the US.

hey raac, i purchased a j2534 flasher, and there was a big relay for the delivery, i finally got it, but when i try to install j2534 chrysler application, it displays this error screen, i don?t know if you are familiar with this that you could help me, or any one who knows about it, i am beginer in these stuffs.
thies is the error screen 197278

[trivilin8]

Hey raac, thanks a lot, I already succeed flashing the pt cruiser, two in fact, it really worked!
Just one more thing, is there a number to look before flashing an ecu to figure out if it's capable? Or if it has the same hardware?
Thanks for all help you have given to me.

Hello, I'm glad to hearing good news from you! - As far as I know...

1) There are "generic" modules, in my previous example the 05034440AD and 05034440AE are generic modules (<Generic>1</Generic>). You could look for these part numbers in https://www.techauthority.com/UserManagedItems/Documents/J-2534%20Flash%20Availability.pdf and check for applications. As a matter of fact all modules installed on a car aren't generic, all modules have been reprogrammed, for example a NGC module typically has 2 stickers on it (one on top of the other), bottom sticker would have the "generic number".

2) If option number 1) is not an option... there is not a number to look... would be really nice! (like in Ford with their "hardware number") - In this case I review physically both modules (as you did it), check if both modules are for the same engine, pinouts, etc...

Hi raac, thanks for all info you have given to me, i appreciate it.

hey, have you flash Toyota ecus with cardaq plus? I've been trying but I think I need registered TIS techstrem, I paid to the original website, but when I try to register it, it redirects to another web page which I don't think it is the right one.
Besides, have you change a calibration for a different type? I mean like you thought me for Chrysler ecus

Thanks in advance

[raac]

Sorry dude, I have no experience with Toyota's ECU.

[trivilin8]

Thanks anyways, I tried to do the same trick, but it changes, in first declare how many updates have been done, and then show them all, I tried but I didn't succeed, I had to swap the EPROM physically. Anyway if I find out how, I post it. Take care man

[trivilin8]

Hi dude, it is I again bothering you. Hey, have you flashed ford ecus with another calibration than it is originally programmed? I need a 2005 f-150 5.4 engine and I have a 2005 f-150 4.6 ecu, both has the same hardware I think because both have printed the same ( PCM-221) on their label. I've been tried but I can't find the way to do it as long as the programming software doesn't allow me to modify the calibration files, in fact it doesn't even show them to me as Chrysler.
Do you now any trick about it you can share please?
Thanks in advance

Hello,

P221 is the Ford's "platform" name for F-150 trucks: Ford P platform - Wikipedia, the free encyclopedia (http://en.wikipedia.org/wiki/Ford_P_platform)

I haven't tried on a car, but in the module (off car, in the bench) works...


Try to start FMP without connecting the module, I mean just power supply for your J2534 interface. FMP will try to establish communications with the CAN network and after a while FMP will show an error saying was unable to communicate with the module, you will have two options: retry or select the model with part number or catchword, select this option, follow on screen instructions and proceed with the "target" part number that you want (i.e., the 5.4L engine), at this point FMP has loaded the "target calibration" and you can proceed with "module installation" to download calibration to the module.


This procedure doesn't work with EEC-V modules (104 terminals).


I would like to hear your tests results.


Regards,

[trivilin8]

Thanks a lot man, I did what you posted, I let j2534 identify the ecu with the engine off, it couldn't so the software asked me to text the part number, I opened the ignition switch till I was asked at the flashing progress, it was a success, the ecu was flashed with the target calibration, the problem was that I think the ecu I used does not have 4x4 capability, it does not work, I think I'm gonna have to find the same part number besides the engine haven't started yet because it was a engine damaged truck that a mechanic sent me to fix, i gotta find out what the problem is.
Anyway, thanks a lot, it was really useful, like always, I hope I to give something back some day.

Hello again, sorry to bother you, but, have you recently performed flashing for ford vehicles? I’ve been trying to purchase a license for FJDS, but always when I click pay after filling credit card data the system goes to a white screen and shows an error related to a mismatch typing. And in the screen where data must been typed it says that card validation can’t be performed.
Am I missing something new?

Thanks in advance

I have full FJDS flashing Ecu´s

Regards,Hello raac, sorry to bother you but, are you still able to do this trick with the current FJDS? Before I did the tip you gave us but now when FJDS doesn't detect module or communications to ecu it takes you back to home menu, I've been trying to change Vin and calibration but I just can't, can you help me up again?

Does anyone know if it's possible to download older EFD files before Chrysler started to encrypt them?
