suzuki gsx 750 k8 93c56 upa read

**Stenberg88** · 6th May, 2021, 09:40 PM

good evening, i'm going to read with a upa clone my 93c56 eeprom on my gsx r750 k9. I found a pic of the pinout to read without unsolder it. My first question is, how can i plug wires into upa? i will use my ktag tips to connect wires on UPA, but n.6 and n.7 pin are not marked, so i think i dont need it.
someone can help me reprogram tacho? since i use smaller sprocket, my odo and kmh are 10% off, is it possible to fix this too?
thanks

but Speed sensor front wheel works ? if yes odo correct

UPA 93c connect need eeprompin list 1 2 3 4 and power pin 5 8
eeprom-UPA
1-7
2-2
3-6
4-3
5-5
8-9
use 3.3V mode if need

My list UPA RS232 pin list

**Stenberg88** · 10th May, 2021, 11:38 PM

hello, today i opened my tacho and found that board is not same as the pic i found for the pinout
if i use same "spot" like cl27 cl28 cl26 cl25 cl9 and cl7, is it same thing? tomorrow i want to try reading with my UPA
thanks

eeprom is open, no points needed.

**Stenberg88** · 11th May, 2021, 06:15 PM

i read in 8 and 16bit. cant read script on upa. Can someone tell me if i did something wrong? are the files corrupted? I need 13450km on tacho
thanks

You post here empty files,didn't see this before upload?

**Stenberg88** · 11th May, 2021, 08:39 PM

yes now i saw it.
im not able to read with upa. All empty file, maybe i used wrong pinout in board... i tried a lot but nothing.

eeprom pin 1234 to UPA RS232pin 7263
eeprom pin 5678 to UPA RS232pin 5--9
SET UPA 3.3Voltage mode hardware and PC software 3.3V
Read 8bit and read 16bit if you no bitmode info

Thanks for your reply, i did It exactly like this, but had "low voltage" on some points...maybe its a upa hardware problem. Now a friend of mine desolder eeprom and try reading on upa 93cxx board. I let you know

If eeprom solder out and back then pin6 direct 0 Ohm with pin8 (16bit) or 0 ohm with pin5 (8bit) 8 16 if this chip works in 2 mode. if no 93C56A or no 93C56B ....

yesterday we tried using clone carprog without success (error verify), today with vvdi we get around 40000km reading with Neox. I have 50000km on the board

is it my file corrupted? we tried reading the one taken with carprog (not verified) and it gave us same reading, around 40000km
here is the file read with vvdi, im trying to have 13450 on tacho
thanks
