I wonder if the 2021’s are using a redesigned unit.
The MIU G4.
On 2nd thought, which BIN are you using? Is it the CM275405/464AVFAL for which I created the BIN? When you open den speedo correction factor, do you see the value 1535?
Is the injector scaling value (ms/g of fuel) only used to display fuel consumption or is it taken into account to adjust injection times?
would it be possible for you to find the correct speedo correction factor on the XDF of the MIUI G3 ECU (V7 III), the current one (0x7C996) is not working...
Hi Chris,the latter. Fuel consumption is just a collateral effect, it's a purely informational value passed over the CANbus to the dashboard.The (rough) procedure is as follows. It starts with an interrupt driven event, which calls a subset of ops including ignition calcs and fuel_value-to-injection-time conversion. Along the way the fuel values (idle fuel/main fuel) are derived from the known tables. Then it branches of into the conversion of the fuel values into a time-based injection pulse width. The result of which is fed into the fuel phase routine, in which the fuel phase tables/scalars define the rotational degree (crankshaft) at which the injectors are closed, eg the current to the injectors begins flowing again to build up the magnetic charge of the coils. (Btw, the same procedure is used for the ignition coils).The injector scaling value is used to convert fuel values to injection pulse width values based on the specs (flow rate at 3bar/coil saturation over voltage/other coil characteristics) of the injectors.CheersMeinolf
