Title: bench reading/writing without immo defeat Post by: volksdude on May 31, 2011, 01:54:26 PM is it possible to bench flash (or just read the flash) on a non-immo defeated ecu?
or the only way would be galleto Boot mode? Title: Re: bench reading/writing without immo defeat Post by: matchew on May 31, 2011, 02:09:25 PM You can read the ECU even if immo is active.
Title: Re: bench reading/writing without immo defeat Post by: carlossus on May 31, 2011, 03:03:56 PM Some, like mine can't be read unless paired with the cluster. That means if the ECU doesn't match it can't pair.
Title: Re: bench reading/writing without immo defeat Post by: volksdude on May 31, 2011, 04:05:34 PM You can read the ECU even if immo is active. well because I try to read my new RN ecu (04 GLI) and nefmoto keeps disconnecting due to the immo... Title: Re: bench reading/writing without immo defeat Post by: thom337 on May 31, 2011, 04:15:20 PM Reading shouldn't be a problem, even without IMMO authorization/bypass. Did you try reading in the vehicle?
Title: Re: bench reading/writing without immo defeat Post by: pvl on June 01, 2011, 04:14:09 AM Hi,
Try KWP2000plus with a benchflash harness... and ME7 edition software from AMT-Cartech. Posted on this forum. Works perfectly. 10 or 20 mins (512/1Mb flashrom), and the job is done. Cheers, PvL Title: Re: bench reading/writing without immo defeat Post by: Tony@NefMoto on September 03, 2011, 01:35:52 PM The immobilizer just forces the ME7.1 ECU to be read in the car. If the ECU is out of the car, you need to defeat the immobilizer, or read the ECU in boot mode.
Title: Re: bench reading/writing without immo defeat Post by: pvl on September 05, 2011, 03:52:18 AM ME7.5 ecu's can be flashed on the bench, with kwp2000+ and mpps without immodefeat and no boot-mode nescessary. Tested this myselfe.

If the ECU is out of the car, you need to defeat the immobilizer, or read the ECU in boot mode. So is this a function of Nef software or the ecu? Our local shop can read/write with a bench harness using a big name tuner's cable/software regardless of the immo state I believe..Unless they are defeating it then re-writing it afterwards? I thought you couldn't read/write on the bench with Nef regardless of the immo state anyway?

If you program the ECU using the NefMoto software, which uses the OEM factory flashing protocols, then some ECUs prevent flashing when the immobilizer cannot communicate with the instrument cluster. Title: Re: bench reading/writing without immo defeat Post by: vwaudiguy on September 05, 2011, 10:16:44 PM Is it possible to boot strap the ecu without opening the case?
Title: Re: bench reading/writing without immo defeat Post by: Tony@NefMoto on September 06, 2011, 12:08:02 PM Is it possible to boot strap the ecu without opening the case? Not unless you add an external switch to the ECU circuit board to allow you to ground the boot pin. Title: Re: bench reading/writing without immo defeat Post by: vwaudiguy on September 06, 2011, 12:13:51 PM Thanks, Tony...Sorry for all the silly questions! ;D

It would take a lot of work. Boot mode flashing is an entirely different protocol than KWP2000. It has been at the back of my mind for a long time though, so maybe I will be able to do it one day.

If I had the time/knowledge to help you out, I would gladly help you but my only practical programming background as of now is PLC logic Title: Re: bench reading/writing without immo defeat Post by: chienliu1972 on October 11, 2011, 05:16:55 AM Is it possible to use Vag K+Can commander 3.6 to disable the IMMO.3 of ME7.5, and use the KWP2000 Plus with ME7-AMT Cartech software to bench flash 29F800BB by bench harness?
The clone KWP2000 Plus with ME7-AMT could let me read the tuned file inside 29F800BB. When I start to flash the ECU, ME7-AMT cleared DTC, then the Me7-AMT stopped in "wake up ECU" and stuck there. My car is 2003 VW Sharan 1.8T automatic AWC / ME7.5 06A906032HA Title: Re: bench reading/writing without immo defeat Post by: thom337 on October 11, 2011, 06:46:12 AM Disabling or "validating" (key, cluster, lock barrel, etc) the immo by any means will allow you to flash on the bench. If you disable the immo, you can flash with KWP-2000, Tony's tool, MPPS, whatever....
Title: Re: bench reading/writing without immo defeat Post by: chienliu1972 on October 11, 2011, 07:11:41 AM The IMMO. 3 is not in my cluster(17-cluster), it is a independent module(25-Immobilizer). So, If I flash the ECU in the car, which fuse of the above two modules should I pull up? Or I do not need to worry about this, the MPPS, NefMoto, and KWP2000 Plus could easily use for flashing the ECU, if they pass through IMMO.3 ?

Not needed to immo off for doing this. "The clone KWP2000 Plus with ME7-AMT could let me read the tuned file inside 29F800BB.

Title: Re: bench reading/writing without immo defeat Post by: chienliu1972 on October 11, 2011, 08:42:34 AM Fig-1 I use KWP2000 Plus clone to read / flash Me7.5 on bench with bench flash harness.
Fig-2 That follow the introduction in this forum to build a self-make bench flash harness. Fig-3 I connect Pin-43 for k-line, Pin-1 & 2 for mass(ground), Pin-21 with 2K resistor for Immo., and Pin-2 & 62 for 12V power. And line to ground pin-24 of 29F800BB with 5k resistor as photo shown. Then I got what I described above. I may have else wrong but I do not know. could anyone advise? Title: Re: bench reading/writing without immo defeat Post by: pvl on October 12, 2011, 03:24:30 PM Hi,
It's about time to do that msn-session with me. I've added you to my contact-list to help you out. Keep the ecu's closed. Let's first try the kwp2000+ interface. It worked for me !!!! Cheergs, PvL Title: Re: bench reading/writing without immo defeat Post by: chienliu1972 on October 19, 2011, 12:34:23 AM After testing by introduced by PVL, I have successfully flashed the ME7.5 ECU.
There needs a simulation on/off switch in line of Pin-3 to ME7.5 ECU. In writing the ECU, ME7-AMT would wake up ECU twice. There should be a simulation of ignition switch on/off when you see the second time "waking ECU up" information in the screen. Then, you could easily use ME7-AMT to flash the ECU. |
