  3. Convertor or Clutch Slip%

    in Link G4

    Posted

    Thanks!

    Manually was recommended in the post

    Using 2 wheel speed sensors, 1 on front and 1 on rear (drag application)

    Can I use the 2 spare wheel speed inputs for this?

     

    How come there are two slip% parameters when setting up logging, why are there two and what's the difference?

     

    Sorry I don't have the ecu fully wired in, just setting it up

  7. Injector Ballast

    Manufacturer has said that the recommended amps to open injector is 5 amps at 12volts

    Do you recommend a smaller resistor to achieve the required amps, since 2.2ohm ballast resistor achieves 4.175 amps at 16.5V?

    Hi,

    I have a 1.8 ohm fuel injector and 16.5-16.7V battery

    In the G4 installation manual it says to use a 2.2 ohm ballast resistor for injectors 0-2 ohm

    I have 4 injectors and will be using 4 injector drivers

    To figure out the injector current draw I did,

    16.7/(1.8+2.2) = 4.175 amps

    Current seems too high and the recommendation in the G4 installation manual seems to low at 2.2 ohm

    What is an expectable injector driver amperage I should be aiming for?

     

    Also can anyway recommend a fuel injector ballast resistor package or box - I know haltech sell one and many oem like WRX, RX7-8 and many Nissan models come with standard from factory

    Anyway know what resistance they are?

     

    Thanks in advance

  12. Knock options

    Based on what test results did the bosch knock sensor out perform other sensors, say the EVO and WRX where in the PClink help files 'Suggested Knock Frequency Settings' you state 13kHz for the EVO and WRX and for the bosch 6kHz?

    Basically what the differences between a good knock sensor and a not so good knock sensor?

    They are both just a knock sensor, all work the same in principle, just like a temp and pressure sensor.
    What really matters is the software and how efficiently and reliably it processes the inputs.

  16. PClink gauges

    Oh that's disappointing to hear....they look appealing

    Would it be too much trouble to add it as an option to the next PClink update?

    I'm sure there are others who would agree with me that they look good faded and with the header backgrounds coloured

    Just a suggestion

    Can't seem to find how to change the colour scheme of my digital gauges from the scheme on the bottom left corner to the digital gauges on the top right

    In the how to use PClink youtube video the gauges automatically configure with the highlighted headings and fading, but mine don't and can't seem to figure out why

    Any ideas?

    I've got the latest PClink software

  20. Knock options

    My understanding is that one requires a bosch knock sensor (or similar) and the knockblock and set ecu settings to ON-DI Knk Interface?

    So what is the ON-Knk Internal knock setting in the ecu and what is required to get it to work?

    What configuration is best, easiest to setup for reading knock?

    Thanks!

  23. Varying Boost control down drag strip

    Thanks will do when it gets going

    Still looking at my options

    Got 4D igntion map for 1st and 2nd gear to reduce timing

    2 boost tables, boost on the start and boost settings for the actual run for each gear

    Got plenty of additional speed and travel sensors for logging

    Should be fun

    Timing is mostly used but so many things can happen between these points that would make your run inconsistent

    Timer switching would require dual switches, one for the clutch and a secondary switch

    GPS would be great where you're able to tune to specific sections of the track. Would be expensive for the sensor and can the link facilitate a GPS sensor?

    Fredrik,

    Can't use traction control here in Australia. That's the regulation ANDRA has placed

    I plan to run a wheelspeed sensor on one of the rear wheels instead of driveshaft speed, as I believe I can utilise this input for more functions 

    Probably have boost control based on gear instead of km/h, would be more consistant

    I'm noticing there are lots of ways to do this

    Would love more boost tables instead of 3 max, got one dedicated to just the launch

    Appreciate your input

    Looking to vary boost pressures down a drag strip

    Most use the timed approach but I'd like to have the boost vary based on driveshaft rpm or wheel speed/rpm 

    I have the driveshaft input rpm set as DI 5 and while setting the 'wastegate %DC1' table x=rpm and y=speed DI 5, the speed DI 5 would go to a maximum of 400. What units are these rpm or km/h?

    Any ideas on the best way to set this up or an alternative method to vary boost pressures down a drag strip?

     

    Thanks in advance

    Paul
