Re: GDI4 ECU current supply
Yes Tim, I've specified that in the post before that I mean low-side PWM, so having an SSR for example in-between the pump and Fuel output of ECU, and controlling the SSR SIGNAL GROUND. Isn't the common practice to have two half-bridge outputs designated for DBW control, thus making a full-bridge? H...

Re: GDI4 ECU current supply
Thank you, Tim! Yes I understand that most of the components that I've listed would have the 12V coming to them from PDM, and ECU sinking/switching the grounds. But how would the fuel outputs be wired if used for lo-side PWM? Say: - two fuel pumps - two water pumps Is the fuel output used as a "...

GDI4 ECU current supply
Hello! I am planning ahead an electrical system for my track car. The ECU is GDI4 and I would like to use it to power directly most of the engine components which (as far as I see from the datasheet it can do): - Lambda (heater) - DBW (58-61) - GDI pump (32,58) - 4 GDI injectors (24-27,51-54) - 4 lo...

Re: Internal Wastegate control: single port/vs two port
Anyone has inputs about the boost lines? I am going to use two thre-port GM solenoids – one for lower and one for upper can of IWG actuator. https://www.rbracing-rsr.com/sq6m_wastegate.html mentions that the boost source (metal port on my solenoid) is plenum, not compressor as I used before for sing...

Re: Internal Wastegate control: single port/vs two port
Thank you mates for the advices! I have some stuff to play with, so will give it a try. I have 35 series MAC valve with three ports, one similar volvo unit that is stock on the motor and two GM units, that are supposed to be very responsive. If even the benefits would not be really perceptible, I st...

Re: Internal Wastegate control: single port/vs two port
Thank you, that would probably allow me to use a low pressure spring right? I actually have a stock valve and a MAC one, so could already make that combo. I have heard advice not to connect the pressure sources with a T but to run two separate hoses to the intake plenum...? (So I could try to repurp...

Internal Wastegate control: single port/vs two port
Hello, I wanted to hear some opinion of the benefits of running two-port internal wastegates (IWG75 by turbosmart) vs a single port, and 4-port MAC valve vs 3-port one correspondingly. I have an ecoboost 2.3 engine, and I am keeping stock turbo but using GDI4 ECU. My car is very light and traction-l...

sensor linearisation in dash items
:?: Hello! Is sensor linearisation available for custom CAN channels -> items? When I create item the linearisation option in math is grey/unelectable . I need to be able to restore the temperature from a IR brake disk sensor sent over can and I have a table I was willing to input in the linearisati...
