  1. Engine fan control

    OK, Thanks!
  2. Engine fan control

    Thank you vey much Clint! No , it is not tested yet because I have to brake in the engine first. I could try it with variable resistors on the temp. sensor connectors. It would be great if someone of the Link support could confirm these Fan control settings. Thanks again. Will give a feedback when tested. Ivo

  4. Engine fan control

    Hi Clint, OK, but when I'm setting the SW Cond2 for Virtual Aux 1-GP Output, there is avaiable only "Aux Virtual value 2=ON (OFF)" from the pull-down menu? It seems I have to use for SW Cond 1 the Virt.Aux1 own on/off state. Only then the pull-down menu offers "Aux Virtual value 1=ON (OFF)". ...Or I'm totally out of space? Please, would you check this again for me? Thank you!
  5. Engine fan control

    OK, Here are my new settings: Virtual Aux 1 as a GP Output: Virtual Aux 1.bmp Virtual Aux 2 (for the intercooler coolant temperature) as a GP Out: Virtual Aux 2.bmp and the FAN control Aux Output set as a GP Out: Fan control Aux as a GP Out.bmp I understand your logic and it corresponds to the examples given in the Help menu. What bothers me is the Fan's GP Output setup. Why SW Cond 2 is again "Aux Virtual Value 1=ON" ? (Actually there is no other choise but "Aux Virtual Value 1=ON" in the "SW Cond" menu!?) What, where from are the values 135 and 75 on the attached screenshot (Fan ctrl as a GP Out)? I didn't put them there. What do you think? Thanks! Ivo PS: Aha! OK! You!!!! have adopted "1" and "2" as Aux Virtual VALUES! for SW Cond 1 and SW Cond 2 ? Does that distinguish for sure betveen Virtual Aux 1 Out and Virt. Aux 2 Out in the Fan Control GPOut setup? SW Cond 1 Aux Virtual Value1 = ON | 1 SW Cond 2 Aux Virtual Value1 = ON | 2

    Thank you Clint! I'll try these settings. It seems though, there is no support for G4 since New Year !??? I hope this wont be "forever"...

    Knock, knock...? Is there anyone from the famous Link tech support?
  8. Engine fan control

    Hello all and Happy New Year! Please, I need an advice how to switch ON and OFF the engine fan based on two different temperatures. The fan is located behind two radiator cores, sealed inbetween. The front core is for the air-water intercooler system. The rear core is the engine cooling radiator. So, my aim is to switch ON the fan based on the ECT and also on the IC coolant temperature (there is a dedicated temp sensor connected and calibrated to AN volt 8 input). So far checked the engine fan AUX output as GP Output with logic cond 1 OR 2 (Cond 1 is ECT. Cond 2 is AN Volt8) and it seems it should work OK. What bothers me is that for GP Output there is no temperature hysteresis value but only a switch OFF timer delay value with max 12s only! That means if any of the temeratures falls slowly, the fan will be switched OFF (after 12s) but the actual coolant teperature drop could be just 2-3 C !? Is there another way or logic for the engine fan control so I could achieve my aim but using OFF Hysteresis temperature for both values? Can I connect another! AUX Out to the same Fan relay pin as the "Engine Fan" Aux Output, so the Fan relay will receive ground signal from two independent Aux Outputs? What function to choose for the other AUX Out? It is G4 Xtreme Red ecu. Thank you! Ivo

  10. Base timing

    Hi Will, May be you should hit the "Enter" button before the "Done" one. Check this thread: http://forums.linkecu.com/index.php?/topic/7172-trigger-offcet-menu-is-locked/
  11. Trigger Offcet menu is locked

    Hello Adam, Just a little feedback. The engine is running on the factory settings. It is pig rich but running. First I tried with -84 deg offcet but received a pop inside the manifold. Then changed to 276 deg and it started like an OEM :-). The timing light showed 277 deg offcet is the perfect match. I checked the settings. The master was 15ms which appears to be too high for my 60lb Siemens Deka injectors at 45psi base pressure. I'm very happy with my Link ECU so far. Especially with the "Differential pressure" channel. A very, very useful thing. I'm still discovering the ecu's possibilities :-)) Here is a short video with the factory settings "in charge" engine start. Only 3"diameter short down pipe from the turbo. The idle is on two wire Bosch solenoid valve. Some problems with the alternator charging because I switched to a LED lamp. Fixed now. Made some changes to the master fuel (13) and the idle table. Also added a straight muffler to the DP. Now I can hear the empty hydr.lifters knockng: Thank you very much! Ivo

    Ah, Now, the Offcet number is already on its place. What confused me so far was that I always tried with the "Done" button in the "Set Base Timing" screen instead to hit the "Enter" one. Everything is OK now!!! Thank you! Ivo
  13. Trigger Offcet menu is locked

    Hello Adam, You're always here when needed ! I'm glad I bought Link Ecu :-)) So.. in the "Set Base Timing" screen I have to enter the -84 (or 276),. hit the Enter button and then to... attempt to crank/start the engine? Also my synch trigger is a "Half moon" type with the window centered exactly "over" the gap on the 60-2 trigger wheel according to the scope. Hall sensor. The synch mode is set to "Cam Level" Are these signal alignment and synch setting correct? Endless thanks again for your support! Ivo
  14. Trigger Offcet menu is locked

    Hello guys, I'm pretty close to the first engine start but I'm in a dead end with the trigger offcet settings. My be I'm blind but I just don't find where to enter my offcet number because the PC Link trigger calibrarion menu is locked for the offcet degree number. My VW VR6 12V engine has 60-2 target wheel on the crank and the TDC 1st cyl is 84 deg (on 14-th tooth) after the gap has passed the CAS in the direction of rotation. My understanding is that I have to enter first the offcet number then the Ref timing number and at the end using a timing light via the "Set Base Timing" sub menue to fine tune the Trigger Offcet degrees. I guess I miss something though. Your advice is highly needed. Thanks! Ivo Here is my pcl file: Vagvaz.pcl Vagvaz.pcl
  15. G4 Xtreme (Red). Wiring of a Drive Low Switch to a Digital Input

    Hello Adamw, No, it is a Hall sensor. I'm explaining how I wired it to my G4. I was advised here to use shielded cable for the Hall sensor as well, but my cable has only 2 wires surrounded by shield. In its original OEM instalation, the Hall wiring consist of just 3 wires, no shield. Thank you!
