Is it possible to modify fuel, ignition tables or maps using realdash on an unlocked ECU? Specifically 98 Audi A4 which has been unlocked using Eurodyne.
Typically this is done by sending a specific CAN message from RealDash to ECU. That message will then activate different maps etc. That part is handled by ECU.
While in theory you could send entire tune, like update maps etc via CAN connection, RealDash is not designed for that. We have made very early decision that we will not make RealDash a “Tuning Software”, as every ECU already has their own which probably does the job better already.
