I would also like to add, confirming that the 27c020 you clear with UV and is written only with the programmer while the 29f010 you can rewrite it directly with the OBD interface read/write (assuming that the ecu is the same as you allow it).

Thanks for the info... I could explain with ecm2001 or 6.3 virtually how to duplicate the file from the 29f010 to 020? I wanted to ask if he could go for a TN28F020-120 28F020 2048K (256K x 8) CMOS FLASH MEMORY Intel PLCC-32 (gi? bought on e-)?Originally Written by rgiubert
the 27c in plcc, do not delete, you can delete the dil with the window through uv rays.To use a 27c020 instead of a 27c010 selections on the programmer, the memory (27c020) then in the device address put start 0 and as the end of the length of a 27c010, the programs the first time, and then imposed as the start for the mets? a 27c020, and as the end of the length of the 27c020 and programs the second time.So you can find the map repeated 2 times.I hope that you understood
In fact, I'm wondering if they are compatible with Flash plcc 32...
For the avoidance of any misunderstanding, I will send you a picture of my programmer cos? tell me where where is the device address, ok?
I the willem I do not know, in the imagine I can see the length (size), but does not start, you have to find you when you load up the map(a 27c010)in the buffer memory of willem start address 0000 end 1fff, in the device, to program the first part of the 29f020 you: start device 0000 end 1fff, and to schedule the second part: start device 2000 end 3fff, on my work cos
ok, I have to try. Another question: as a concept, if I instead of doing all these operations, memorizzassi the file from 1Mega, the other Mega on the eprom should not be written, and then would be the empty space in FFF, there? it means that the ecu would read the file that you need (the cio? 1M), as happens for example on a usb stick or on a hard disk, am I wrong? If yes, I could explain in detail why? should not work?
you have to see if the unit starts to read from 0000 or 2000, if it starts from 0000 no problem I think, but if it starts from 2000 finds nothing.I with the old tdd 039 where the map was, if I remember correctly that is contained in a 27c128 dil, I used a 27c256 where in the first part I put on the map and in the second to another map, then there was a pin of the eprom that if the hop-state logic high(5v) was the work of a map, while if you put a low(ground) worked the other.
Boh!... Gi? that we are, and I see that you have experience on the 27c128 dil, I have a Delta integrale that I would like to map, only that I can not find the 27sf128/256, why? I would like to avoid buying the uv oven.... you could give me some clarification? You have had the experience on these ecu's?
I and my ecu I have used it also on a few race cars, modified the bp to get up to 8000 rpm (The last on these ecu stops around 6500 rpm) and the bp load to be able to work on all the curves, I used one of the eight valves,
to map it I have always used an emulator in real time, otherwise these transformations, you got to be crazy(the ecu ? born to work from 300-400 to 2000-2200mbar of a turbo engine, but with a naturally-aspirated arrived to 1000mbar cos? we were to use the met? yes and no load curves if we altered the bp).With regard to twenty-four? of the memories ? a nice problem to? in any case, a toaster oven should have it, already? can't find the memories if not then you can delete them and you have to do some testing ? a casino.
Beautiful, only that an emulator of the genre where can I find it (maybe used at low cost) and how much will it cost me? How does it work practically? Replacing the eprom with one connected to the computer, and then the emulator? I would be interested also for the tdi plcc32!...
