Title: Gen 2 immo delete to fit 1.8t into an old GTI Post by: slimwadey on March 08, 2013, 02:24:19 PM Hi all
I have decided to fit an Audi TT ARY code 1.8t into a 1989 Golf GTI Trouble is the ECU that comes with the car has the gen 2 immo built in and i would need the clocks to run the engine So i want to do an immo defeat to not need the clocks I have a pretty good understanding of PCB work and reading/writing flash files (.bin) as i have done about 40 Xbox Jtag mods over the years, all using various methods and software, i have spent plenty of time with CMD too so have no issue there (but i may be a bit rusty as i learned it all way back in the 80'/90's) So far the guys on the regular chat forum i use are all saying i need to send it off and pay someone to do it, but i think i can do it myself with the skills i have and a little bit more info I dont have the ECU at this moment as i am picking up the engine and ECU next weekend so i cant give any numbers at the mo Is it a case of removing an SMD chip, slotting it in an eeprom reader, reading, fiddling with the file and re flashing ?? Or will i need a virgin ECU file and then build an image from scratch ? I also want to delete a few other bits of info from the ecu too but right now its the Immo that needs to go Any pointers to read as a start ? Thanks Steve Title: Re: Gen 2 immo delete to fit 1.8t into an old GTI Post by: ddillenger on March 08, 2013, 04:04:43 PM If the car has an me7.5 ecu, it's very easy. You can read/write the eeprom while still on the ecu, you'll just need to put it in bootmode (search if you are unfamiliar with the term).
When you pull the file post it and I'll off it for you (or if it's immo-3 I'll tell you how to do it yourself). Title: Re: Gen 2 immo delete to fit 1.8t into an old GTI Post by: slimwadey on March 09, 2013, 02:50:42 PM Thanks for the info
I'll have a read up about bootmode Would i need a harness to do it without opening the ECU ? if so whats needed and from where An Eeprom reader is cheap and soldering i free ..

I advise including a separate switch to the ignition pin. Title: Re: Gen 2 immo delete to fit 1.8t into an old GTI Post by: slimwadey on March 09, 2013, 03:35:17 PM Thanks
I have ordered a galetto cable and will slowly gather the bits i need, sorry for the questions, i know it can be a pain, but at least i'm not in the same crowd as the guys who want a complete free remap for MORE POWER !!! with some drawing pins and blu tac!!

LOL (laugh out loud) Title: Re: Gen 2 immo delete to fit 1.8t into an old GTI Post by: slimwadey on March 14, 2013, 04:19:10 PM My new Galleto cable arrived today ! Yay me
Can i use it without a laptop ? i have need to connect it to a car, just an ECU when my pre made cable arrives too (lazy ? me ? .. Er Yes !) I only have a really old laptop that i never use anymore, its got XP as it cant handle anything better Steve Title: Re: Gen 2 immo delete to fit 1.8t into an old GTI Post by: vdubnation on March 14, 2013, 09:51:25 PM My new Galleto cable arrived today !

I only have a really old laptop that i never use anymore, its got XP as it cant handle anything better Steve I think your confusing something you can read the eeprom without taking anything out of the car over OBD with your laptop in command prompt in order for you to defeat the immobilizer your going to have to take the ecu out rig it up to a bench harness or if your on the fly like me sometimes i crack open the ecu while connected to the car i ground the correct pin to get into bootmode "dont recommend this way" and push the defeated file over with my laptop in command prompt waaaalaaaaa your immo is gone.

No i'm not confusing things I understand i will be doing this off the car with the a Galletto cable and another pre made cable that is a basically a bench rig infact the ECU is not even in a car as the car has been sold I want to know if i NEED a laptop or if i can use my Desktop, i dont think i will need a laptop to do it as the desktop does the same thing..... on a desk rather than say, my lap ... I have the Galletto And this lead is on the way too (http://www.gigacrusher.co.uk/images/lead1.jpg) Title: Re: Gen 2 immo delete to fit 1.8t into an old GTI Post by: ddillenger on March 15, 2013, 03:42:43 PM Desktop works fine for bench flashing.

Title: Re: Gen 2 immo delete to fit 1.8t into an old GTI Post by: slimwadey on March 27, 2013, 02:11:14 PM well all part i need are here
The pre made ECU to OBD adaptor was junk, did not fit, i assume it was for another ECU So i chopped it up made my own Ok i now have the ECU connected to my rig and my galetto cable, i have powered the ECU with a nice supply I cant seem to read anything from my ECU I have tried nefmoto and get 'failed to read test echo from ftdi device' I'm pretty sure i have the driver installed ok So i try the galetto software, after grounding pin 24 following this pic (http://nefariousmotorsports.com/forum/index.php?action=dlattach;topic=417.0;attach=1319;image) it keeps saying bootmode inactive I have tried 20 ish times and even timed the 5 secs any pointers ? Title: Re: Gen 2 immo delete to fit 1.8t into an old GTI Post by: slimwadey on March 27, 2013, 02:23:23 PM Another question
Does the ECU need to be powered with a constant live on pin 3, then switch power on pin 62 to simulate ignition on/off? (http://wiki.obdtuning.com/images/a/ac/VAG_ME7.x.jpg) Title: Re: Gen 2 immo delete to fit 1.8t into an old GTI Post by: slimwadey on March 27, 2013, 03:17:02 PM Ok so i used a switch on pin 62 and a switch for the earth too , i have checked both connections and they are fine
But no boot mode yet (http://www.gigacrusher.co.uk/images/eflash1.jpg) (http://www.gigacrusher.co.uk/images/eflash2.jpg) (http://www.gigacrusher.co.uk/images/eflash3.jpg) (http://www.gigacrusher.co.uk/images/eflash4.jpg) Title: Re: Gen 2 immo delete to fit 1.8t into an old GTI Post by: slimwadey on March 27, 2013, 03:25:27 PM just wanted to say i have checked continuity on all lines , all are fine
Should pin 3 be switched 12v and pin 63 permanent live ? I have it wired the opposite way pin 3 permanent live and pin 63 switched live My Galleto cable has a red light on and i'm selecting Audi Ecu's , vw/audi ME7.5 xxx 29F400BB, although i cant find any numbers on the ECU that correspond to this in any way Title: Re: Gen 2 immo delete to fit 1.8t into an old GTI Post by: ddillenger on March 27, 2013, 03:26:51 PM You need to power ecu pin 21! This is true for all immobilizer equipped me7's AFAIK.
Title: Re: Gen 2 immo delete to fit 1.8t into an old GTI Post by: slimwadey on March 27, 2013, 04:35:07 PM Ahhh !!!
Is this as well as pin 63 or instead of ? Thanks for the help Title: Re: Gen 2 immo delete to fit 1.8t into an old GTI Post by: ddillenger on March 27, 2013, 04:44:44 PM Pin 63 is left blank. Pin 62 gets 12v. Take a look at the diagram you posted. It's accurate.
Title: Re: Gen 2 immo delete to fit 1.8t into an old GTI Post by: slimwadey on March 27, 2013, 04:51:50 PM sorry i was reading 62 and writing 63 ::)
i have been using 62 not 63 So let me get this straight Pin3 is permanent live, pin 21 is switched and pin 62 is powered too, switched with 21 or perma live ? Thanks again Steve Title: Re: Gen 2 immo delete to fit 1.8t into an old GTI Post by: ddillenger on March 27, 2013, 05:37:10 PM I just have them all hooked up to the 12v power source. When I power up the ecu they all get powered up. When I power it down, they all get powered down.
Title: Re: Gen 2 immo delete to fit 1.8t into an old GTI Post by: slimwadey on March 27, 2013, 05:58:02 PM Still no luck ::)
I think its either : low power, i'm getting 12.8/12.9v not 13v + or ECU is KAPUT .... maybe due to the pad of pin 24 lifting off the PCB after me soldering a wire to it, but i re soldered onto the actual LEG of the pin and it seems fine (pic tomorrow) or maybe something to do with the cable serial number (unless this only applies to Nefmoto software) not really sure what i'm talking about on this bit so i'll shut up and read a bit more I'm sure i'm doing everything right as the cable seems to be recognised in the galetto software and Nefmoto Or its beacuse its on com port 3 Steve Title: Re: Gen 2 immo delete to fit 1.8t into an old GTI Post by: slimwadey on March 28, 2013, 11:40:25 AM any ideas anyone??
Title: Re: Gen 2 immo delete to fit 1.8t into an old GTI Post by: cyril279 on March 29, 2013, 06:01:34 AM So let me get this straight Pin3 is permanent live, pin 21 is switched and pin 62 is powered too, switched with 21 or perma live ? Thanks again Steve pin 3 is ignition switched. All the other 12v pins see 12v all the time. putting a switch on pin3, and using that switch to initiate ecu power, made it a lot easier for me to get into bootmode. voltage shouldn't be an issue, I get bootmode using an 11.5v supply. -Cyril Title: Re: Gen 2 immo delete to fit 1.8t into an old GTI Post by: slimwadey on March 31, 2013, 07:38:24 AM pin 3 is ignition switched.

I have Re wired my harness so it has switched 12v on No3 pin and constant 12v on 21 and 62, the kline is connected correctly and all earths are fine My pin 24 ground switch works too , all connections to ECU have been tested with a multimeter Still i get no response from galetto or Nefmoto Does the USB have to talk to a certain port ? Could i have a dead ECU ? Any help would be appreciated Steve Title: Re: Gen 2 immo delete to fit 1.8t into an old GTI Post by: ddillenger on April 02, 2013, 02:08:43 PM You are running the galletto drivers with the software right? Did you edit the program to show the correct serial number of your cable (or edit the serial number of the cable to match the software)?
Title: Re: Gen 2 immo delete to fit 1.8t into an old GTI Post by: slimwadey on April 02, 2013, 02:47:50 PM i'm using the driver i downloaded from your 'proper english' version as well as the software from you
I have not changed any serials yet as i cant seem to find the software serial with the hex editor you recommend, i am using a big wide screen monitor and the numbers are VERY small i can get my serial by dumping it using nefmoto This is what i get <?xml version="1.0"?> <FTDIDevicesFile Version="1.0.0.0"> <Devices> <Devices> <Description>USB <-> Serial Cable</Description> <Flags>1</Flags> <ID>67330049</ID> <LocId>0</LocId> <SerialNumber>47514789</SerialNumber> <Type>FT_DEVICE_232R</Type> <Index>0</Index> <ChipID>0</ChipID> </Devices> </Devices> </FTDIDevicesFile> Title: Re: Gen 2 immo delete to fit 1.8t into an old GTI Post by: ddillenger on April 02, 2013, 02:52:11 PM 47514789 is the serial that comes with the galletto software, so you're good there.
Title: Re: Gen 2 immo delete to fit 1.8t into an old GTI Post by: slimwadey on April 02, 2013, 02:53:27 PM Damn
i thought this may have been the issue >:( Title: Re: Gen 2 immo delete to fit 1.8t into an old GTI Post by: slimwadey on April 05, 2013, 01:35:29 PM After studying some pics it occurs to me iam not using pin 1 as earth just Pin 2 , would this matter?
Should i use both ? Title: Re: Gen 2 immo delete to fit 1.8t into an old GTI Post by: ddillenger on April 05, 2013, 01:38:09 PM I use both. Not sure how necessary it is, but if you've tried everything else, it can't hurt.
Title: Re: Gen 2 immo delete to fit 1.8t into an old GTI Post by: slimwadey on April 05, 2013, 02:25:12 PM Still no good
i'm getting frustrated ??? Title: Re: Gen 2 immo delete to fit 1.8t into an old GTI Post by: slimwadey on April 19, 2013, 02:02:39 PM After weeks of not getting into boot mode i am about to throw in the towel
No matter what i do i cant read via galetto or Nefmoto Iam using a windows 7 PC with a galetto cable and home made harness, stable power supply I have permanent live on pins 21 and 62 and switched live on pin 3 Both pin 1 and 2 have ground K line is connected to Pin 43 I have an earth switch on the leg of the chip pin 24 going to the outer board earth ring I am pretty sure all my connections are good, i have used my multimeter to check continuity of all wires right from the powers and earths from the supply, thru the cable and into the ECU, even thru the pin connections on the board , also checked the earth switch i am using Could i be having an issue with drivers or the port of the PC ? I can read the serial of the cable via the nefmoto software so i must have some kind of connectivity Do i need to do anything special on the PC? my PC has lots of USB ports and i just use one of the front ones When i plug the cable in and power everything up i get a red light on the cable but it has a slight green glow to it too, as if a small LED is on as well as a big red one, the green is quite hard to see unless you tilt the plug to see it When i plug the cable into the PC i get the usb connected noise The driver i am using is the one found on the Nefmoto page as the one that came with the cable said it had a virus when i tried to use it Can anyone point me to a guide to removing then downloading and installing the driver correctly just in case i have done it wrong ? Of course i may have a damaged ECU and wont know this until i try another, the car this came from was driving when it had an accident so WAS running, i can only assume it was working OK, i cant really afford another ECU just yet Please help a frustrated soul on his journey to crack this IMMO !! Thanks Steve PS the OBD connector where the light is gets warm, is this normal ? |
