Please, can anyone confirm what is the max frequency input for the DI channels of G4 Xtreme Red?

It appears up to about 480Hz the spikes are missing According to the text below for turbo speed input, the max DI frequency is 500Hz !!! Is that true? A Digital Input can be used to measure turbo shaft speed. Once configured, turbo speed can be used as an axis parameter on tables. Note: An interface box must be used between the turbo speed sensor and the ECU. The interface box must have an output frequency of less than 500Hz at full turbo speed

Very useful video! Thanks for that, but it could help me with my future projects. Both my current sensors are VR type, i.e. inductive. The well working is an OEM ABS one. It has visible 3 thin flat metal cores visible that read the teeth. The problem one is ex OEM crankshaft position/rpm sensor. It has one round center core that reads the teeth. I guess it has about 900 Ohm resistanse. Anyway, I learned something new. Thanks! Also checked the DI 3 signal as frequency. It had the same spikes. It could be signal noise but why only at speeds >115km/h !?

Hello, My drive wheel speed sensor signal/frequency is making me nervous. Up to approx 115 km/h the drive wheel speed (DI3) matches perfectly with the driven wheel speed (DI 1). Above about 115km/h though, the drive speed starts to have spikes of approx +80 km/h above the driven wheel speed. According to the tunng manual, I changed the setting of DI3 from Rising Edge to Falling Edge but the complaint remained unchanged. The driven wheel sensor is an OEM ABS one. 8 tooth trigger wheel. The drive speed sensor is a VR one as well but originally made for reading engine rpm. Its trigger wheell has 8 teeth and is located on the gearbox output shaft flange. With this issue I can't set the wheel slip ratio. Any advice is welcome. Endless thanks in advance! Here is link for downloading a log file with the problem: https://dox.abv.bg/download?id=7fb7c5f2a7#

Yes, The PC log is perfect. I'll try higher frequency next time. Thanks again!

Here it is Kris, It is a bit larger than 4.32kB Thanks for you time! Menwhile I opened some log file with all parameters visible which appeared to be PC logged, but I'm not sure how exactly it was stored. What have I done to save it on my PC.

Hello all, I need help please! Recently I realized I just can't open and view my log files. I can open and see just the provided with the PCLink two sample logs. Today I downloaded and saved on my PC all 10 available log files in my ecu via the ECU Controls -> ECU Log File Download ->Save file as. A bit later at home I tried to view the files as Time Plot but after selecting the needed parameters they just don't appear on the time plot. What I'm doing is as follows: Open PCLink->In Logging open a log file->choose Time Plot-> Add parameter-> Press OK. Also I have hard times to understand when PC logging is set up what happens with the ECU logging? Do they log at the same time? Is there any difference between a PC log file and a ECU log file? It looks like the ECU log file includes lesser number of parameters. Is that correct? A log file downloaded from my ecu is attached. Thank you! new7.llg

Hello all, Please, I need help to understand the ecu statistics. First of all, I have some doubts about the numbers in my ecu's stats . I bought my ecu used and before the first tuning attempt I did restore to factoy settings. Does that also resets the available in the ecu acumulated up to now statistic data? Are engine running time and starts real numbers? How exactly are defined? What exactly is considered as engine start and engine running time? Thank you!

Hello! Is this possible? Thanks!

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

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.

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

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!

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.

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.

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!

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.

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!

May be here : https://www.hpacademy.com/ you could find the answers

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
