  1. @Adamw I am currently doing exactly as you say, but it is consuming a PWM output, a digital input that can handle the frequency, and a 3D table in the software just to do one simple calculation. Hence why I believe the math function should be added, but whether it should be added or not, it doesn't matter if the hardware won't support it. So I get that.
  2. I had asked a while back when the G4x wasn't released yet if Link could add a way of comparing two analog values to control an output (in my case I am controlling IC fans with the differential temperature of two temp sensors) and I never heard anything back on whether this could be implemented. I realize a majority of the requests on the wish list cannot be added, but this seems like a pretty basic and highly useful function to add to the software. So recently I was poking around in the G4x software and noticed you added the "Math" functions in the "ECU Settings" tab which is exactly what I wa
  3. @Adamw...Sorry this took longer than I expected, but here is a log from today. This is a base map that is surprisingly close up to 10psi and in light throttle, but I was wary of taking it to redline with the tune being the way it is. I did however take it up to 5k rpm and historically, this motor has been the noisiest around 4200-4500 rpm. You will see a noise spike right as I let off the throttle, but I am assuming this is normal or can be disregarded; because there is virtually no load. Log 2020-06-23 8;29;25 am.llg
  4. Hey, thanks for the fast response. I will most likely be taking the car out today and I will log it. I will upload it once it's done.
  5. Can anyone tell me what knock level gains they used for each cylinder of a 3sgte when using a Bosch 2-wire knock sensor? I have everything else set up, but I would feel more sure about myself if I could verify the values that I came up with. I am a beginner in the tuning aspect of things, but very competent on the electrical and programming side of things. When dialing in the knock level gains, I am not confident that I am adjusting for the noisiest rpm of the motor or if it is actual knock. So I don't want to set my gains to low that a knock event doesn't surpass the threshold. Just for refer
  6. 9 virtual outputs sounds higher than what I have currently. I think it is something around 6. I will have to do a firmware update tonight. Thanks for the info.
  7. Would it be possible to add more Virtual I/O to the existing amount on the Link G4+ platform. I am running out as I like to use them for latching purposes, mostly for outputs that do not have 3 logic rules and I sometimes use them for additional logic if I just can't fit all of my conditions into one output logic structure. I'm not sure if this is an easy task or not, but I'm sure I am not the only one on here that ran out of virtual outputs to use. (FYI...I am running a G4+ Xtreme, not sure if the amount of Virtual I/O) is different for each ecu model)
  8. Alright so I figured this out right after my last post, but I ended up with a little different solution than I planned. I figured I would post this on here so anyone else that needs to accomplish this can use my method. There is a CON to this method...it will use up an PWM capable AUX Output and a Digital Input. So attached below are the configurations I set up. Basically I used my AUX 7 channel as a PWM output, in which I keep the Duty Cycle constant at 10% across the whole table (I have one AN Input on one axis and another AN Input that I am comparing to on the other axis). Then I utili
  9. It would be nice if a user could add an algebraic expression in the G4+ PC Link software somewhere that can be stored as a general value (such as Virtual AN Input). Essentially I am looking for a user defined algebraic function that you can use values from other inputs on the PCM to convert into a value that can be used to control auxiliary outputs. For instance, "|(AN Volt 1) - (AN Volt 2)| = (Virtual AN Volt 5)"...….this could be used to control an output off of differential temperature. I don't know which would be the easiest way to allow for this, but I feel like a "Virtual AN In
  10. Alright I think I have this solved and there are multiple ways of doing it. In the PWM output function...there is an option to vary frequency of the output which is defined in a table. I can make each axis the two temperatures I am comparing, but this time the table will be defined to proportionally increase the frequency output based off of the differential temp. I think I will increase the frequency 1hz per 1 deg of differential temp (See table below). This will give me the temp range I need. Then I will either feed that frequency output back into a digital channel and assign that channel as
  11. I had the same idea about making my switch over point in the table only 1 deg apart, but the table would not give me the temperature range I needed.
  12. Just realized you we’re suggesting using the PWM output as essentially a discrete signal (on or off). This I think would work as long as I keep the switch over point from 0 to 100% duty cycle linear in the table and the ecu does not store temperature values as anything other than an integer. I’m going to have to try this in excel first to see if it’s possible. Essentially the table will look something like this as long as both axis are scaled the same and have the same offset for temp. On another note, what is the resolution of the AN Volt channels?
  13. This brings up a good topic. Are you saying you can connect SSR to a PWM signal from the ecu to create your own PWM speed controller? I was wondering if the frequency wouldn’t be high enough. On the other note about the dash...I was thinking of going with the AIM MXG 7” since Link does not have their own 7” dash on the market yet. Is there anything plans to release a Link 7” dash to the market to compliment the 5”?
  14. It is not essential, you are right. I am either going to use the value to give a visual alarm on the digital dash that the A2W IC system failed (which wouldn't need a value) and I might use the value to calculate heat dissipation from the IC heat exchangers (I have temp sensors all across the IC system). My end goal here is to optimize the A2W IC system over time...so I want to log the temperatures throughout the system and water flow. I could use "g/s" as "gallons per second", but that would make it a very small number. lol
  15. So I am looking to control an GP Output (A2W Heat Exchanger Fan) with the differential temperature between two temperature inputs. I would be using the logic that when the differential temperature between the ambient air temp and the IC Heat Exchanger water output reaches a certain level, I will turn on the fans. My question is, how do you compare these two analog input channels in the G4+ software to control the output. Worst comes to worse, I wire the two sensors into a voltage divider type circuit externally (which would feed a single differential signal back to the ecu), but I would r
