Title: Audi V8 4.2 immo off Post by: kaross on April 10, 2013, 02:48:56 AM Hi!
I have one old Audi V8 engine which we want to put in another car, so I am looking how to immo off this. I don't know which type of motornic it is, but I know that people here know Motronics well. On M2.3.2 I know how to immo off in fuel chipset, but here can't find right bits. Title: Re: Audi V8 4.2 immo off Post by: Acki on April 10, 2013, 03:37:42 AM It's a Audi C4 A6 engine, S6 4.2 V8 290HP - code AEC.
Audi V8 - D11 is only 3.6 PT and 4.2 ABH. Title: Re: Audi V8 4.2 immo off Post by: cyril279 on April 10, 2013, 04:39:20 AM kaross, you've attached the main bin, immo-off bits are probably in the eeprom.
Title: Re: Audi V8 4.2 immo off Post by: Acki on April 10, 2013, 05:07:42 AM Code is different in some areas. But don't have a AEC ECM to test code changes directly :(
Would be nice too know if the AEC dataset has measuring blocks :( Title: Re: Audi V8 4.2 immo off Post by: prj on April 10, 2013, 05:12:44 AM kaross, you've attached the main bin, immo-off bits are probably in the eeprom. EEPROM on a M2.4? :D Title: Re: Audi V8 4.2 immo off Post by: kaross on April 10, 2013, 06:04:48 AM no there isn't eeprom.
immo can be switched off from this *.bin*. I know it for sure. most of Motronics (I think all) have immo routine in main .bin and it can be deactivated. Even in MED9.1. I have it running immo off from flash. EEPROM is just one way. Also I am 99% sure that this file is from Audi V8 MY1994. one of last. Title: Re: Audi V8 4.2 immo off Post by: cyril279 on April 10, 2013, 06:06:38 AM EEPROM on a M2.4? :D my appologies Kaross, it seems I've stepped out of my league... :-[ Title: Re: Audi V8 4.2 immo off Post by: Acki on April 10, 2013, 10:30:56 AM Use the ABH software.
I have tried the AEC software on my ABH ECM. Engine starts for 2s and then stalls. Diagnostic is the same as ABH has at VAG COM. So no benefit. Only the same mods at the fuel map I try now. Title: Re: Audi V8 4.2 immo off Post by: prj on April 10, 2013, 11:10:24 AM The reason it stalls is because your car has no immo.
Title: Re: Audi V8 4.2 immo off Post by: Acki on April 10, 2013, 11:16:24 AM Yes. DTC for immo is set.
But diagnostic offers not more information so no sense in removal. Use ABH software and everything should be fine. Title: Re: Audi V8 4.2 immo off Post by: kaross on April 10, 2013, 12:14:36 PM can you, please post this soft?
Title: Re: Audi V8 4.2 immo off Post by: Acki on April 10, 2013, 01:58:24 PM I will Upload it tomorrow.
Title: Re: Audi V8 4.2 immo off Post by: Acki on April 11, 2013, 12:36:57 AM Changing ECM part number etc. to have the correct information at VAG COM should be easily possible for everybody ;)
Title: Re: Audi V8 4.2 immo off Post by: kaross on April 11, 2013, 04:35:32 AM That's no problem. :)
I hope this will work. Title: Re: Audi V8 4.2 immo off Post by: prj on April 11, 2013, 04:59:16 AM It should work, it's the same like you can do on 2.2T by using different revision of software without immo enabled.
