    Hi Darryn
    Lucky it is nearly possible, would be nice if Link made it easier.
    To act like the Davies controller, you need the following.
    To give on/off @ min 5V PWM at low temps you have to use Timer 1, Activation = Virtual Aux 1, Max Time = 40 sec, Polarity = Reset When On. Then set Virtual aux output 1, Switch Logic = Cond 1 AND 2 AND 3, SW Cond 1 = Timer 1 > 39.99, SW Cond 2 = RPM > 600, SW Cond 3 = ECT < (Your Set Temp - 20).
    Use Timer 2, Activation = Virtual Aux 2, Max Time = 20 sec, Polarity = Reset When On. Then set Virtual aux output 2, Switch Logic = Cond 1 AND 2, SW Cond 1 = Timer 2 > 19.99, SW Cond 2 = ECT > (Your Set Temp - 20)
    For running after stopping the engine, I have a race car and the power to the LINK is always on. So you need to retain power on to the LINK ECU.  With the above control and engine stopped the pump will keep running until the ECT drops below your Set temp - 20. The Link cannot do a shut off timer sorry, one option of fitting a external turbo cool down timer relay which controls the power to the LINK.
    How
    Setup the working aux output as GP PWM, Frequency = 80 Hz, SWOffTimer = 0, Switch Logic = Cond 1 OR 2 OR 3, Sw Cond 1 = Timer 1 < 10, Sw Cond 2 = Timer 2 < 10, Sw Cond 3 = ECT > Set Temp.
    SET the Aux PWM graph, as single axis X as ECT (axis y = none). Now the hard part, what values should you enter?? It will be trial & error method, but start with your ECT at (set temp - 5) & below = 20? (being 5 Volts at the pump) and ECT at (set temp + 5) & above = 100 (full voltage). The idea is the LINK will interpolate between and settle hopefully around the set temp.

    I heard you cry HELP, it should not be this hard. Just remember I any on your side. So Simon of Link what are your comments???
    Cheers and good luck

    Hi Cozcorners
    There is many options, it depends on your requirement.
    Yes setting Log Trigger to rpm > 50  would work fine. You there using 800 rpm ????
    My option is for my race car.  So if speed > 25kph start logging until ignition is turn off.   Allows the race engine to warmup and NOT record data during warmup, therefore saving memory to allow fast & many data points recording during the race.
     
    Possible explanation for your NOT logging, there MAY be a limit in the firmware on the number of recording starts. So once you start recording keep it active until the end. Only one start.

    Andy Drummond got a reaction from Simon in VE calculation   
    Hi Guys
    I was running the above setup about 6 months ago, Had the same problem the VE fuel tables values were very small. So compared air per cyl values and found by reducing the engine capacity from 1752 to 250 cc was able to have VE table around 70% WOT.
    What setting makes this happen is "Equation Load Source:  Load = BAP"
    Have since changed to Load = MAP  and all is good.
    Solution for you is wait for correction from Link, or change your engine capacity value,  or if possible switch to "Load = MAP".
    Hope this helps and best of luck.
    Cheers
    Andy
