Link G4 stream to racepak iq3

[Jon.C]

are there any general settings ore an file that can be transfered in to the can setting for iq3 on the link g4? 

i have some deviation in the readings between racepak dash and ecu values. 

if there is no file to insert what kind of values should the can settings be?

thanks, 

Jon

Hi Jon

For CAN we send the data as follows on the Generic Dash stream.

Generic Dash CAN Data Format

 

All parameters are sent as 16 bit unsigned numbers, with low byte first.  Some parameters must be multiplied or offset (constant value added) to get the correct calibrated value.  The limits flags are sent through as a bit field (described below).
