Tacho Universal Sync Error

[marcolr]

hi all friends . today i received from china a new tach pro with blue pcb. i try to connect in my audi s3 via OBD but nothing ....... neither the screen nor anything lit by the new device .... after several times plugging and unplugging the power cord the screen lit but had nothing but a blue only blue .... nothing else. please let whoever can help me solve my problem ...i attached some pictures maybe help us...

When you say "several times plugging and unplugging the power cord " wath?s you mean? you plug the OBD and you plug the the power cable?
If you plug the OBD cable, you don?t plug the power cable. The tacho is powered by OBD port.
For Audi S3 you need to know wath type of dash the car have. You can check this with vag-com for example or take off the dash and look at the reference.
Depends of wath type dash you have and wath year, you can make by OBD or by dash connector or by eeprom. You know?

when plug via power cable not anything in my lcd
when plug via odd nothing again.
when plug power cable and obd the lcd havent only a blue color ,.......nothing else.what im doing wrong?

[marcolr]

You made bad at first connecting OBD cable and power. Now Tacho don?t work anymore. It is possible that some component has been burnt or data of any of the flashes are corrupt.

hey guys, I've tried programming eeprom data onto my chips, hc11 and hc12 and the 24c02, but it still shows sync, so im going to use a null modem cable and connect it and do the repair/update and hope that works! however can someone please either post the correct .exe file to do the update/repair? my TU says "Jan 24 2008" under version when its turned on? i believe there are 2 different update/repair programs and i want to make sure i use the correct one!

Thanks guys
