gus Posted September 22, 2008 Share Posted September 22, 2008 Hello. I've two td5 ecu with bad fuel remap. The ecu's don't start, are dead. I am trying to program the 29F200 flash eprom outside the ecu with a eprom programer. The problem is that i don't know how is the native td5 file for a NNN000120. Can anybody send me a original map of a td5 ecu?. With it, i'll can see where is the variant and where is the fuel map. Thank you. Quote Link to comment Share on other sites More sharing options...
Guest diesel_jim Posted September 22, 2008 Share Posted September 22, 2008 Porny (Ian) will be your man for this one i suspect. Have you got a nanocom? the software for that has all the factory programs in it, but you need the nanocom to program them to the ECU. judging from what you're saying, you have an earlier ECU that's non flashable? hence why you've got the EPROM connected to an outside programmer?

No jim, they are flashable ecu's, NNN000120. The problem is that both has an interrupted remap. My friend used an old nanocom with the 16mhz cristal. The nanocom crashed before end the program, and now the ecu's don't start. I am an expert nanocom user, but i think that It is imposble to resolve the problem without extracting the 29f200 flash of the ecu. Quote Link to comment Share on other sites More sharing options...
BogMonster Posted September 22, 2008 Share Posted September 22, 2008 Do I deduce from this that to a certain extent with a Nanocom you get what you pay for? I agree that Porny is the man to speak to. Quote Link to comment Share on other sites More sharing options...
henk Posted September 23, 2008 Share Posted September 23, 2008 I agree that Porny is the man to speak to. I would talk to Pete Bell, also here on this forum. He can program ecu's Quote Link to comment Share on other sites More sharing options...

Oh yes, sorry, my mistake, thats the same part number as my ECU has. I just booted up the nanocom "map wizard" which has all the factory files on it, and (looking at the attachment below) It looks like it's that file that's needed for euro spec 110 (it's the one with the most recent date on it) PM me your email and i'll fling it over (can't attach it here) Quote Link to comment Share on other sites More sharing options...
gus Posted September 23, 2008 Author Share Posted September 23, 2008 The nanocom map wizard generate original map files wich you can send to de the ecu via OBD II. The ECU run a internal routine, and write this maps in the flash. But when you have the 29f200 in your hand and you want write them with a eprom programer, you need the complete memory image, 256k. I can read these image from a good ecu, but It is very dificile of extracting the flash SMD. Quote Link to comment Share on other sites More sharing options...
Bell-Auto-Services Posted September 24, 2008 Share Posted September 24, 2008 Im the person you want , this is just up my street loool Give me the ecu part number and the NNW software code of the files you need in 256K 29F200 form and i will make/write them for you from scratch no problems.

Bell-Auto-Services Posted September 24, 2008 Share Posted September 24, 2008 Or if you are willing to reprogram the software here is a virgin file that will repair the damaged data on the chip but will need nanocom to write the correct software for your car after you resolder to the pcb. Basicly this file will get you communications to the ecu again, then use nanocom to correct the software you need. www.bellautoservices.co.uk/Virgin-No-Vin-NNN000120.rar The rar has a password you will need to email or pm me for it. I will also be removing the file from me server in 1 day so i hope you get it in time If you have a nanocom and are botherd about using it then tell me what software you want creating and ill make it special for you. Regards Pete PS bogmonster you are right and i agree Quote Link to comment Share on other sites More sharing options...
Bell-Auto-Services Posted September 25, 2008 Share Posted September 25, 2008 File is now removed from my server as you have got it gus. Let me know how you get on , or if you need any info give me a shout ill do my best to help you. Regards Pete Quote Link to comment Share on other sites More sharing options...
gus Posted September 25, 2008 Author Share Posted September 25, 2008 Yes Pete, I`ve got it. Thank you. Now I am waiting for a programmer with 48 pins and a psop44 adapter, using it i will write your file, solder the flash in the ECU, and pray for the ecu start again. thanks Quote Link to comment Share on other sites More sharing options...
Bell-Auto-Services Posted September 25, 2008 Share Posted September 25, 2008 It will sart again 100% , as said you may have to change/reprogram the correct software type with nanocom and possibily make secruity function again. But it will work Quote Link to comment Share on other sites More sharing options...
chiper Posted April 24, 2009 Share Posted April 24, 2009 very interesting read. I have a the same problem, there was a bad galletto file flashed to an ecu of my mates defender, I now have this ecu and have lifted the 29f200 chip and read it in my willem, I have ordered a nanocom from devon 4x4 but they have ran out of stock so I am still waiting on the manafactuters to supply them.I do have the original galletto file(16kb) but I need the full 256kb file or a virgin file any help would be gretfully appreciated, the ecu is a NNN500020 nnw501290 4189 55 defender. thanks great forum shane.

volta Posted April 14, 2010 Share Posted April 14, 2010 Hello, I have exactly the same problem as Gus and Chiper! By loading an original fuelmap file, the cable obd between my Nanocom and the' ecu was disconnected. Since this, the ECU is dumb! Would anybody have a virgin file which I can put in a 29F200 to return my ECU in good condition? The photos of the label on the ECU: Question to Chiper: what reference of Willem do you have? Because I have to buy one! Sorry for my bad English, but i'm a little "Froggy" and i traduce with a translation software! Quote Link to comment Share on other sites More sharing options...
volta Posted May 27, 2010 Share Posted May 27, 2010 Hello. problem solved for me. i have desoldered the EPROM reprogram it with virgin file, and resolder. thank you to Gus for his help. Quote Link to comment Share on other sites More sharing options...
XELB LAND Posted August 24, 2011 Share Posted August 24, 2011 Hello! I`ve got a problem with the ECU codes...no sticker on it...(NNN000120) Yesterday we remove the 29F200, and delete all the files, but now i don`tknow if it go to work. I wrote a original map, but it seems to have 16Kb and not 256... How can i find the code or get a virgin file for that. Thanks! Best regards from Portugal!!!
