Ok thanks no use anyway since we can’t get a pinout!

I have a few e67s with jacked up virtual eeproms, other than J tag can if easily be fixed? Takes me two hours to J-tag a e67 at 60 an hour I can also buy another used one for that price! From j tag experience it’s definitely only a section of the main chip. Should just be a simple for loop, or are w...

That is partly due to missing tutorial. Can you give some screenshot what happens or log, is there any idle traffic from ipc on screen. The usual usage will be settings-> select device->configure device->connect button. Thanks for all your help! I really do need to take some time and learn this too...

I see my mistake so, si, clk are not what I need I think txdo and rxdo are separate and I’ll never find it! Without a data sheet I’ll be forced to shelve this.

Hopefully someone at nec or the nec forum will respond with a proper data sheet.

Trouble is I need to invert rts and dtr for vcc and flmd0 to be pulled up to 5 volts. I’m thinking a simple pull up bread board circuit with 5 volt power from my e67 pcm could work? But can you control each pin with pyserial python on the keyspan 19hs like you can on a proper ftdi 232? FTDI <-> 78K0...

Oh ok. I don’t think the eeprom will allow me to make those changes since they were never available from the factory I’d need to create new code and find a code cave to patch it into the stock firmware. More on reading the chip.. found vcc, sdi, so, sck, ground Only two more pins on the 8 pin port t...

The mileage is definitely not programmed by sps. You must send the cluster out to a special repair facility. That being said it’s easy to change I have done so several times it’s on the 93c56 eeprom, which is programmed with a ch314a I think. Anyway I’m wanting to change more now I want to add tire ...

Correction I think it’s a .pr5 file?

More progress on the chip .. found SI30, SO30, SK30 Vcc and vss should be easy enough, but vpp/vmdo and reset will be tough to find without a proper reference manual. Chip is definitely a NEC upd78f0835 qfp 100-pin 14x14 mm fine Closest chip a found is the upd78f0833y it has on board j1850, as I’m s...

Ok I uploaded the script in vpw console seems to be working but I don't see any response from the cluster.. were is that stored?
