I'd imagine the new ECU will also have a 5P08C3 Eeprom, so I'm going to have to desolder and re-program it. While I'm at it, I'm going to put an 8-pin socket into both ECUs so I don't have to desolder and resolder when something like this happens. I've definitely had the car down longer than I had hoped but in due time it'll be back. It's definitely been a learning experience.

EDIT: No need to desolder. I bought a Gq-3X programmer and Ponoma 5250 clip.

I got my immobilizer eeprom from my original ECU. I'm about to turn the immobilizer off but I want to know how to keep the immobilizer active. The 12 and 22 bytes are 01. I know they should be 02 for "Immo off" but is "Immo On" 00 and 01 is "Immo Armed"? Attached is my current Eeprom dump from a GQ-3X programmer.

Do I need to clear some stored codes in the eeprom in order to start the car too?

EDIT: Another question. If I have IMMO 3, I need a 7-digit number(SKC) instead of a 4-digit(0XXXX), right? If so, where is this in the immo eeprom bin? Also, in order to clone my original ECU, all I need to do is copy over the VIN and SKC info, correct? What areas should I copy and which areas should be untouched to truly clone?

EDIT2: I found this post which should help a lot. http://nefariousmotorsports.com/forum/index.php?topic=899.0
I'm trying to leave a big crumb trail in this thread so it'll be an educational thread for most.

Thanks,
Sean

I tried an immo defeat on the original ECU and zeroing out all of the 170-1B0 to hopefully remove the Programming Not Finished DTC but that didn't work. I immo defeated my second ECU but when I turned the ignition on the car did the normal door chime but then three distinctly louder beeps and then continued the door open chime. I'll post my eeprom BINs here in a while.

I can't get Nefmoto to recognize my blue cable even though VCDS connects. I'm trying to do a full read to clear this code. I'll post up my BINs of my Eeproms and hopefully someone can chime in on what I need to do to get this new ECU to work with my car in place of the original.

Couldn't attach the BINs to the previous post when editing, or so I think.

The ECU1-Immoarmed.bin is my as is dump for my original ECU. It's named that way because I thought the BIN file would just have the 33 death code.

So, now I'm on to figuring out why Nefmoto won't connect to my ECU but VCDS will.

Have you tried Galletto over OBD ?

No, does Galletto work outside of boot mode? I'll install the cable later today and see what happens. I'll also uninstall and reinstall Nefmoto to see if that might be an issue.

Thanks, prj.

I also found this post here: http://nefariousmotorsports.com/forum/index.php?topic=1508.msg14326#msg14326

I'll try installing the latest CDM driver. Not sure why VCDS would connect and Nefmoto wouldn't though. However, it's probably my weak understanding of the communication protocols...but I'm getting there.

I got the car up and running. The issue with my Nefmoto connectivity was indeed the outdated FTDI driver. I had a 1.0.*.* driver from 2004 and I ended up using an up to date driver. I connected, read the flash and turned off the ignition to finish the programming session and all was well.

Just a note for those using my thread to go through the same issue(s) I had. I ran into another problem when trying to update the driver. I got a BSOD every time I tried to install the new driver. If you run into this issue you need to go into C:\System32\ and run FTDIUNIN.exe in Windows 2000 compatibility mode and THEN install the new driver to avoid the BSOD.

Thanks for all of your guys' help and this forum as a resource.

To keep this thread complete. Here is a picture of the Immo. Eeprom to clarify the pinout. I hooked it up to the programmer to read a multitude of different ways and it didn't hurt/affect the Eeprom. But, for the sake of it...

If you have the data sheet for the uC, then it's pretty easy, as it's easy to see which pins are ground on the board.
