    12v PWM Output

    Hi all, I am in the process of fitting a Pierburg CWA50 chargecooler pump (commonly used on BMW X5M). This is speed controllable via PWM, and it expects 12v input on the PWM pin. I'm using Aux 6 on a G4+ Extreme. Am I right in believing that the PWM outputs can only switch to ground (otherwise they are floating) - which appears to be the opposite of what I need here? I'm happy to build a small circuit (or buy something) to convert this Negative-switched PWM signal into a positive-switched PWM signal. I can (to get it up and running) feed it 12v through a 1k resistor, which will set the pump at full speed, but I would like to be able to control it via my shiny ECU. Cheers in advance!

    12v PWM Output

    Thanks Richard and Adam. I spent a while looking through the manual but obviously didn't realise that at 0% duty it's actually outputting 12v, I thought it was floating. That makes life a lot easier, and I'll invert the values in the table I've already started to put together. Cheers for the quick responses! Garry

    Change the table to a 3D table, and you can change the axis values.

    1967 Ford Anglia 105E

    Hi all, Now that I've got it running quite nicely, thought I'd show off my 1967 Ford Anglia 105E. This has a Mitsubishi Legnum/Galant VR-4 6A13TT engine - a 2.5 litre, 24 valve, quad cam, twin turbo V6. As there's no space in the engine bay, the original MAF setup is gone, replaced with the Link G4+ Xtreme. Added a Subaru E-Throttle because the Xtreme can support it. There's no intercooler, instead I'm using a 6x4 barrel-style chargecooler, so the overall inlet length is miniscule - the standard TD03 turbos spooled up quick in the original car, they're even quicker now without 10ft of inlet and a large intercooler to compress! Driveline is Nissan 200SX 5-speed gearbox and V-LSD, on custom made fully independent and adjustable rear suspension. Only running 185/60/13 tyres on the back, so traction is an issue in all weathers! Threw it on the dyno yesterday, fairly happy with the result - 324hp/360ft-lb at the wheels... if you take an estimated 18% power loss through transmission, that makes it ~382hp/424ft-lb at the flywheel. Originally I was using the standard Mitsubishi ECU and a MAP-ECU piggy-back to eliminate the MAF, but it never really ran right. Purchased the Link earlier this year, and it has been fantastic so far, very easy to tweak and manipulate, adding DBW only took a couple of hours, and I've got cruise control working (ish, apart from the overshooting the set speed on hitting the Resume button), which even my daily (a Mitsubishi Legnum VR-4) doesn't have! I will start playing with setting up Launch Control and Traction Control soon to try to get this power down onto the road better, and not that I really need it, but Anti-Lag too, just because I can!

    Windows Tablet Dash Configeration

    Did you copy it from the flash drive to the laptop before opening it from the laptop hard drive? Sounds like it was opened from the flash drive, so when it's unplugged, it can't find it, so reverts to the default on the hard drive.

    Laptop recommendation

    If your tablet works, then just grab a USB or Bluetooth keyboard for it I personally use my Dell XPS13 laptop, it's small, light, and has great battery life and good screen.

    Recover lost log files?

    A few of us want auto-saving of logs, and to be able to define a default location, as I think once they're on the PC and not saved, they're gone...

    Ability to control two 3 or 4 ports

    You'd not get the trimming, but my initial thoughts is that you could potentially set one output up as a GP PWM output, with a 3D table. You could use this as your low pressure WGDC table, and then use specific WGDC tables, trims etc to tweak your high pressure accordingly.

    Tablet logging stops if screen is turned off

    I noticed the same thing with my Dell XPS laptop, running on Windows 10. Once the screen switches off (either due to the power saving time-out, or by closing the lid), logging appears to stop.

    Disable "Engine Fan" functionality

    Hi, My Mitsubishi 6A13TT engine has a PWM controlled fan, and I have a chargecooler fitted, so am always wanting *some* airflow over the radiators. I have no output set up as Engine Fan, and have set up a GP PWM output to satisfy the fan speeds based upon road speed and coolant temperature, based upon the OEM ECU's control of the fan, but changing the top left cell to always give me airflow, even if not up to temperature: (The values are inverted, as the fan controller is pulled to ground to activate, 0% duty here is full speed on the fan) However - I am still getting effects of the "Engine Fan" functionality internally - the one I noticed was the additional Idle Speed Step (which, when originally driving a stepper motor was an extra 10 steps, then when I installed E-Throttle an extra 10%!). I have of course now modified the Idle Speed steps, but I'm wondering if there's any other places I've not found yet that the default Engine Fan functionality may affect. Thanks! Garry

    Disable "Engine Fan" functionality

    Hi Adam, Thanks, glad it's not just me going mad! I'll tweak the temps for fan control in the meantime, as you suggest. Just had a look through a log, and one to add to the list, Fuel -> Fuel Corrections -> Idle Load Trims also has a Fan trim which appears to be applied too. Not got AC so hopefully all of that stuff is disabled

    Disable "Engine Fan" functionality

    Hi Adam, Thanks for prompt reply! No outputs currently set up as Engine Fan (although I have configured and ran this with an Engine Fan output set up previously, in case that's relevant, maybe something lingering somewhere that's not being unset) Attached is my tune. Anglia 2017-05-21 08-33 Fan speeds corrected.pclr Cheers!

    G4+ Evo 4-8 Plugin, Speed Sources and E-Throttle

    Makes perfect sense, thanks!
  15. Hi, Am getting some prep work done to fit a G4+ to my Ford Anglia running a Mitsubishi 6A13TT engine in a couple of weeks. First question is regarding speed sensors, which I'll be looking to utilise for both launch control and traction control (~300 bhp in a small, light RWD car on tiny tyres is a little bit of a handful). I've got an existing speed sensor hooked up sensing the propshaft->diff mounting bolts, which detects 4 pulses per revolution of the propshaft, giving a total of 14536 pules per mile (185/60/13 tyres, and a 3.916:1 diff) or 9038 pules per km (if my calculations are correct!) I'm also adding another sensor to one of the front wheels, which will pick up on the 4 bolts on back of the hub that hold the brake disc on, giving just 3796 pulses per mile (175/60/13 tyres) or 2360 pules per km. Would I be right in saying that under the Digital Input setup, I would set the Calibration values to: Rear: 904, Front: 236, which will then allow the ECU to see the same speed from both sets of wheels? Additionally, under Slip Filter in the help, it mentions the potential values being 0 to 8, but I can't then see any further explanation of what this range means. The link to % Slip Calculation doesn't provide any further info on the Slip Filter values. Secondly, I am looking to fit an E-Throttle. The manual regarding wiring for E-Throttle talks about a dedicated +14v input for Aux 9/10 to drive the E-Throttle, but I haven't been able to find in the pinout which pin provides this additional power input on the Evo 4-8 with E-Throttle board. Thanks - I'm sure there'll be a few more questions when I look into a little more of it!

    G4+ Evo 4-8 Plugin, Speed Sources and E-Throttle

    Hi Simon, Thanks for the prompt reply. Glad to hear I won't need to worry about more power feeds & relays for the E-Throttle Is the filtering used if I don't get a clean, smooth signal from the speed sensor, for example if there's electrical noise and it suddenly reads a much higher frequency for a split-second? But, the side-effect is that when the signal is clean, it'll have a slight delay?

    Change the default location for PCLink log files

    +4 I'd like to change the default save folder to my Dropbox folder, so as soon as I get within range of wireless it'll automatically back it up, and I can then view it on another machine with a better display.
