I have been testing this for the last 8 months with no problems.


Change all EKP values:
CHARACTERISTIC CURVES, FUNCTIONS, FAULT LIMITS, PUMP PARAMETERS and DATE, PUMP IDENTIFICATION and CHECKSUM ELECTRONICALLY CONTROLLED FUEL PUMP (EKP)
from value 50 to 51
(E90,E91,E92,E93,E87,E88,E81,E82,E84+!ETHANOL_E100 )+(N20,N55)+PU11+EKP_CI_13)

The EKP control unit controls the speed of the EKP by means of pulse width modulation of the EKP output voltage according to the fuel request. The supply characteristic curve of the EKP for the corresponding model series is stored in the coding data. The EKP control unit ensures reliable activation of the EKP up to a system voltage including 6 V.
The Digital Engine Electronics (DME) control unit or Digital Diesel Electronics (DDE) send the requirement request for the amount of fuel currently need to the EKP control unit.
The communication of the EKP control unit with the DME/DDE control unit takes place across the PT-CAN. The required fuel rate is passed on to the EKP control unit by the DME/DDE control unit in a message across the PT-CAN.

The data for the electronically controlled fuel pump system is encoded as follows:

- In the DME control unit or DDE control unit: engine- and model-related characteristic curves for fuel delivery according to requirements.

- In the EKP control unit: specific characteristic curves for the relevant fuel system (= fuel flow rate for cooling and lubrication of the fuel system)

The control variable is sent in the form of a CAN message to the fuel pump control module (EKPS). The control variable is sent in the unit l/h. The value range is 0-254 l/h.

Desired pressure and flow rate can be achieved by manually adjusting the data values for the CHARACTERISTIC CURVES.

I can confirm this. Been running it for the last 6 months. Can run straight E85 with stock fuel pumps.

Please, we need more details.

Do these characteristics curves allow us to run e85 or does the fact that it is not e100 mess things up?
Do we need a backend flash to take advantage of this or is it straight coding?
With this coding, can we actually run 100% e85 on a Pure Turbo?

This could be huge.

Indeed please more details?

Does your AFR still look like this?

AFR needs to be adjusted.
