  1. Strange, there is no Idle Load Fuel trim for the Power Steer. There is just Air ConTrim, Engine Fan trim and Drive trim. Anyway, I'll configure the DI as an Air Con Request
  2. Thank you Adam! I also thought it should be something using a DI. BTW you meant Aux 7, not Aux 5. Right ? Great support as always from the Link team. No matter how old is your ECU. That's just amazing! Thanks again.
  3. Hello Adam, Unfortunately I forgot to take a log from the moment of idle rpms sink. I'll do that when I get back to the car. Here is my pcl file. The fan is wired to AUX 7. Again, what I can read in the Help Manual, G4 ECU Tuning Functions>Fuel>Idle Load Trims is related only about when "Engine Fan" output is activated. The same is with the Idle speed control settings and the "Engine Fan Step". Thank you! 050921.pcl
  4. Hello all! The work on the car was postponed for a long time. Just recently the engine was started again and... here is the thread revival. I need help thoughThe problem I'm facing is with the idle rpm control. My radiator fan is switching ON and OFF as per the control logic described above. So far so good but when it turns ON the idle rpms sink down remarkably due to the initial generator el. load. Tried to add ms fuel and % PWM idle valve corrections when the fan kicks in but without success. Then I realized that these idle rpm corrections/compensations might work only when the output is configured as "Engine Fan" . This is not the case with my current Fan control output that is configured as "GP Output" so I could implement the logic. If that's correct, how could I add the same idle control corrections when a "GP" Output controls the engine fan? Thanks!
  5. Just wanted to clear the VAG coil wiring diagram. These coils have two ground connections when in the OEM installation . One is for the secondary coil - wired to the cyl head. The second is for the coil driver - wired to the chassis/ecu ground.
  6. Hi, Unfortunately it is not fully tested yet. The car is in a body preparation period, so no more engine starts lately. I did test these fan settings once though. The fan turned on as expected on the set engine coolant temperature. I had not enuogh time to play with the IC water temperature settings to trigger the fan.
  7. 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!
  8. 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.
  9. 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!
  10. 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!
  11. 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!
  12. May be here : https://www.hpacademy.com/ you could find the answers
  13. 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
