  1. Modelled fuel equation values seem high

    in G4x

    Posted

    Could someone have a quick look at my setup for Modelled fuelling?  I've just swapped in a set of 1000cc injectors,  I'm running a fuel pressure sensor and a differential of 4bar.  I was going to use 3 bar but for some reason my FPR wouldn't go low enough when in vaccum when set to 3 Bar diff pressure  I seem to be getting really high number in the VE table and I'm starting to think I've missed something

  8. New injectors, worth changing to modelled fuel?

    in G4x

    Posted

    I'm getting rid of the standard 540cc side feed injectors on my GT four and will be upgrading to a set of new bosch 1000cc top feed injectors.  Since I've fitted an adjustable FPR, fuel pressure sensor and am going to have to redo my fuel map anyway will it be better switching to modelled fuel as I'll have all the injector data required?

  9. Closed loop boost control Boost target

    in G4x

    Posted

    I've got my boost control set to a pretty solid 15psi in open loop so I thought I'd have a go at closed loop but for some reason it was just trying to reduce duty cycle at 12psi by the max clamp.  Is the boost target an absolute value?  So I should be aiming for around 30psi abs to get 15 psi mgp?

  15. Strategy to manage Toyota MR2 SW20 Power Steering Module

    in G4x

    Posted

    From memory I think the pump operation is quite basic.  It runs at 100% up until a certain road speed then switches to a lower setting (maybe through a resistor i'm not 100%)  I know that's how they controlled there fuel pumps at the time.  I'd assuming there's some sort of valve in the rack that lightens the steering if the pump speed gets above a curtain point

  18. Fault codes saved when engine turned off

    in WishList

    Posted

    I've just done a 4 hour drive down the country and the CE light came on.  As I had no laptop I had no way of reading the codes and once I turned the engine off the fault had gone. Now it looks like it was due to my EGT going of or my set range but it would be nice if the code was stored until reset, just to give me an idea where to look through the logs.

  19. Can Lambda error

    in G4x

    Posted

    I've installed my Can / Lambda unit and can get to the point where I can see it in the Can devices list, however it doesn't register any values and in the runtime values shows "Lambda error" I'n the "can" section of the runtime values there are no errors reported

     

     

     

  21. Can bus wiring requirements

    in G4x

    Posted

    So I've finally had enough of trying to find out why whenever I have a high electrical load the ecu needs to add as much as 10% fuel correction in closed loop to say on the desired lambda.  I'm hoping the problem is my analoge widband so I've orderd a Can/Lambda module.

    My Question is I alread have a 4 pin connector which used to be for the stock narrowband sensor which has 12v, ground and 2 cables feeding back to the ecu (originally signal and heater switch).  Can these be used as canH and canL or will there be problems with interference as they are ran with the rest of the cables in the engine loom?

    If I can use them is there a type of cable that should be used which connecting Can modules?  I'm an electrician by trade but have no experience of this typr of system.

  22. Absolute pressure sensors

    in G4x

    Posted

    I understand if a pressure sensor is absolute the you need to account for that in the calibration table.  What i was wondering is if there's a way to subtract the value from the built in Baro sensor to account for changes when not at sea level instead of simply just removing 1 bar?

  23. Honeywell fuel pressure sensor?

    in G4x

    Posted

    Great, I've had a different Honeywell pressure sensor ordered for ages now but I've been waiting 6 months now so I've given up.  Although I can theoretically get cheaper sensors I know this will be ready to collect tomorrow and I've got a 4 hour drive that I want to do some logging with.

  24. Honeywell fuel pressure sensor?

    Could someone tell me if the following sensor would be suitable as a fuel pressure sensor (petrol) and what calibration values I should use when setting it up

  25. Few questions about Parallels compatability

    in G4x

    Posted

    I'm trying to figure out what causing the random disconnetions when using my Mac/parralels I've emailed their technincal department and as expected they deflected and pointed the figure elswhere.  Could someone from link have a quick read through this so I can back to them please?

    Hello David,

    Thank you for contacting Parallels Support. 

    From your email, we understand that you are facing issues to use Link ECU.

    We checked the screenshot and unable to find any issues. We request you to contact Link ECU and check if their product works in a virtual machine. We understand that you have tested it in a Windows PC but unlike a PC, a virtual machine is running in an application on a macOS which has limitations.

    Let us know if you have any additional questions.  

    Thank you for your time and cooperation!
