Foxflash Failed to Read Simos 12 via OBD

Solution:

foxflash cannot read simos 12 via obd if there is no file in server. Foxflash engineer will upload vr file to server once it is available.

You can read and write in boot mode.

How to Find Bosch ECU Serial Numbers and Correct Pinouts

Image
 Here is basic post for people asking basic questions, apparently now on high demand since we have gathered again new members in our ECU group . So you got bosch ecu in hand from car and how to figure out how to identify it and what pinout to use? On this case we can randomly take one bosch ecu that we will identify. So all bosch ecus start with serial numbers 028… 026. We just head to bosches page next https://www.bosch-repair-service.com/ Here you search by oe or bosch number, i have random bosch ecu here and it’s 0 281 014 544 and bosch page ends up with a result. We can see its edc16cp35. Now there are two ways. Either to search in foxflash bmw / edc16cp35 for pinout. Or we head to ecu pinout page and figure out pinout from there. One of the best online pinout catalogs can be found at ecu desing, So save webpage https://ecu.design/ecu-pinout/ Copy address and head out there. Type in edc16cp35, bmw uses two processors in this one mpc 562 and mpc564. Pinouts jus...
