the vn calais

well people im having some problems getting data logging to work with the usb conversion. cant get a connection, tried many different com port settings, re installed drivers, imported ads file. ose flashtool doesnt detect any ecu. the usb comms board power led is on. followed the instructions and solder bonded with the boards pads, so im assuming if its bonded theres a connection. maybe i need to desolder and try again.

Why are you importing an ADS file? Just use the 12P ADX in the package

Are the Tx and Rx LEDs flashing when trying to connect? Ignore echo should be on for the USB. Also, if the Tx LED is on solid the ECU is in limp mode or your running a VN memcal still?

For the flashtool select "VR '808 ($12 type code)", choose the comm port the USB is on and tick the Ignore Echo box. Thats all that is required for the 808 and USB.

yeah tru tru vl400, but i thought id just do one thing at a time and get the usb comms working before setting up the nvram with 12p. so yep at the moment its the stock vn memcal. but ill stay up and do the nvram 12p setup tonight i think, im warming up for another 7 nightshifts- fuk i hate nights

Just chuck the 12P NVRAM in, no need to solder in the RW wire until you want to write to it - will connect and log without it.

up and running on 12p. flashtool connects finds $12p device, and i can log intermittently with the key on reds, but as soon as i start it, ERROR and then no more connect until restarting tp. swear i went through all this once before. bare with me 808 is all new once i get the setup happening ill be sweet as. will have a play with the connection macro tomorrow.

Can you successfully do a get bin using the flashtool?

What if you don't plug in the USB cable until after the engine is running?
I had a similar thing happen at one point, and put it down to possibly a ground loop between the laptop and the ECU.

will try that festy. 99% of time its settings in the connection macro causing issues ive found but.
