I have clone UPA, not work on NEC Mcu?

[88diablo]

I dont have clone UPA so dont know but I was just trying some things to eliminate for you and if you got clone then I would start there.

Thanks mate, if you have any idea... The clone is a goog quality from Carsung, but is a clone...
If is a problem with 78KO adapter on UPA clones then there are not a solution for this adapter?? On forum not information about problem with adapter (at least I have not seen)

[88diablo]

I dont have clone UPA so cant comment but for this car I use cheap chinese programmer which also does algo for you. I dont buy from these people in link but my people dont have it on their site anymore as is old so I post you this link to show you what to buy. I think I,ve seen them on FleaBay cheaper than this too. NEC DASHBOARD PROGRAMMER (http://www.ecutool.com/NEC-DASHBOARD-PROGRAMMER_106.html)

Clone UPA and adapter working good with NEC. I've done a few (in circuit)... Did you remove jumper J3 from NEC adapter? That was my first mistake when I used first time.

Sorry mate... I don't have pinout... To read I followed pictures found here on forum and UPA's own PDF instruction and all worked out well...

I found pinout and After power up needles move to position, oil level blink few swconds, and some lights are on, gauge and stop light are blinking, but km not are showed
May be kill Nec MCU?

Why you powered up dash ? Did you read MCU ? Upa work great with NEC mcu ...not sure for clone but original work online and on adapter....

Not sure about this one... Never powered this one on table. Not showing even for a second? Maybe works only on vehicle together with bsi... Wish I could help you more... :blue:

Mate i power up dash because i'm thinking the Mcu is dead, normally when power up can see kilometers, but in this dash i'm not sure,can you confirm that? never do one of this with Nec processor. Today try on board adapter, tomorrow i will try to connect direct on PCB

Is possible need BSI to show km, but i don't know

[MACKIE]

This dashboard have CAN communication with BSI why dont you put back in the car and see what you have done...

For now BSI was already modified, the car is not in my garage. I will try to do tomorrow Dash, if not work then i must go to the car and connect again

[ruffles1986]

Today i connect direct on PCB and same problem... baudrate error. For now i follow steps by NYO4, but viewing Tachosoft solution i see that BSI Valeo with 68HC912DG128 is only necessary modify data from BSI.
Instruction: read the 68HC912DG128 chip from the BSI (Valeo), and
edit the mileage as shown here. Then connect dash to the connectors .
on the car WITHOUT the BSI. Put the key to the ignition, but do not start!!!
just power on the dash. Dash value will self deletes.
After this connect the BSI and km value will be automatically loaded from BSI to dash.

Sombody can confirm if this work??
