[OVERSPEED]

Can someone post an picture of board with high quality to check the values ?

Well...

the problens:

1) LM is not beeing actived (pin 5 to ground) guess is a problem with T7, managed it grounding direct LM pin 5, now I have about 11,6V in 12V lines

If You have less than it you shold change R32 and/or R33 (look for LM data sheet) to somethng about 10x the low value.

2) Program 16V Wire, it didn?t work (guess it shall be enable only by software when needed, because I measure about 15V before FT1 or it?s something like the issue 1)

3) The major issue:

If I start the software and after plug OBD it enable all protocols (became green), And show ID, firmware and status.

but if I plug 12V charger only JTAG and Utilities keep green, all other becames gray and ID, firmware and status became "unknown" and piasini didn?t work more until I unplug 12V charger, USB, exit the program and start again.

Can someone point me some hint or direction ?


Dont worth to return back because of Brazil tax and shipping value.

I have same problem. With 12v plugged in it went grey and only j tag was green . what is problem ?

Didn?t had any progress with it... if you discover anything please inform !!!

Anyone ever use a clone Piasini to read a Mazda 5 RF7N ECU? Really don't want to kill this ECU with it....it's probably impossible to find a second-hand ECU for it here, so I'm afraid a bit to try...

obdtools the uk site, No im not connected :>

piasini working Denso mazda 6, no issues, all green on Protocols., 12V
perfect read & Write. also cd i got with sw, had keygen,
no emails to activate, so far all good
if interested will post pic of board

Was that by obd or on the bench ?

Does anyone know of a china clone that works flash voltage and k line without problem ?

[pulsar2000]

not obd, bench tune job

Solution for 16V :

- R41 0.2 Om
- R40 200 Om
- R43 820 Om
- L2 220 uH

For board as in post #140...

Not it work also on obd plug i use original cmdflash cable for obd

Got my Piasini yesterday, and I also have a problem with voltages. Managed to change some components according to michael122's instructions, and now I have about 16,4V on 16V line (yellow wire) and 11,4V on 12V line (red) but if there's a load on the 12V line, voltage falls back to about 10,5V. I don't really think that is enough, anyone got any more suggestions what to change?

Try change resistor R32 to 22kohm now is I think 19,1 kohm

where are the problem clones comming from ?

obd2s.com was excellent my contacts had 5 last year and all were good

My solution for k-line :

I replaced the R23 and R28 to the resistors 39k and replaced by SI9241 .

I did not have in stock 9241, so I mounted the L9637 (according to datasheet) , and R21 replaced by 4.7 kOm to optimize L9376.
Now the K-line is working properly

I have same problem. With 12v plugged in it went grey and only j tag was green . what is problem ?

Update - i have found R8 is missing off my board. What does R8 do ?
