    EGT Conditioner

    A happy chap here! As was promissed, here are the Reveltronics wiring instructions: Then I wired the EGT-K OUTs to G4's AN V10 and AN V11. I left the input GND floating and connected the G4 sensor GND only to the EGT-K OUT GNDs. Everything is OK now! I have EGT live data. Since I'm on budget, I used China made EGTs, it appeared the + is RED and - is BLK. Thanks again to Link's and Reveltronics support! You were just great!

    EGT Conditioner

    Hi to all, Unfortunately it seems I have left my EGT-K wiring instructions in my garage, which is located not where I live. Next few days I'll try to pass by and collect the wiring and then to scan/picture it. But it is not something special. I don't see any quoted power consumption, but will ask. BTW I connected the guys from Reveltronics with the same question. Here is their responce: "OUT ground is internally connected to EGT power supply ground. You can left it foating for not grounded thermocouple (thermocouple for vehicles are usually not grounded).All vehicle sensors have ground from vehicle ground.EGT-K power supply ground is also vehicle ground, so both grounds are connected via vehicle ground.Just connect only OUTx to your ECU AdcX input." To me, It looks not so correct for my case at least where all sensors have "Sensor GND" from the G4 ECU, not from the vehicle GND. What do you think? Thanks again! P.S. Also invited them to join the forum and comment into this thread.

    EGT Conditioner

    Hi all, Just bought a 2ch EGT-K amplifier from Reveltronics.com: https://www.reveltronics.com/en/products/egt-k-thermocouple-amplifier-type-k-0-5v What bothers me is the fact (according to the insructions) that the OUT GND is internally connected to the device power GND i.e. to the chassis GND. So , the EGT-K OUT1 and OUT2 are connected to two of my G4 AN Volt input channels. So far, so good but what G4 GND should I wire to the EGT-K OUT GND? If I wire the G4's sensor GND, I'll actually conect that sensor GND to the chassis via the EGT-K device? Is that OK for the G4's all other sensors and measurement? Endless thanks in advance! Regards!

    Hello Adam, I'm confused a bit because I've already swapped the trig 1 wires according the manual. Please, would you check that again? Now, I have falling signal line at the missing tooth zero-crossing, i.e. from high to low. Thank you!

    Hi guys, Just want to ask if you see something unusual on the next picture. The setings are described earlier in this thread. What bothers me is the 0.5V noise on the low level of the synch Hall signal. The Hall sensor is 12V powered but the output trace has 5V amplitude. Is that normal? Thank you!

    OK, Thanks!

    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

    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!

    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?

    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
