chickeneatman Posted April 29, 2022 Report Share Posted April 29, 2022 The G4X help page has this listed for MAF estimated: Mass Air Flow Estimated Displays the current estimated air flowing into the engine in grams per second (g/s). This value is based off of the user specified volumetric efficiency (Fuel Table in Modelled mode). For Air per Cylinder Estimated to work correctly the Fuel Equation Mode must be set to Modelled or Modelled - Multi Fuel, Engine Capacity must be set correctly and the ECU must have a working calibrated MAP sensor. I have all of these params setup correctly and I am running Modelled - Multi Fuel. The Load (Abs) is available, and so is Air per Cylinder Estimated. I am attempting to figure out the 'efficiency curve' of my blower so I can calculate theoretical effects of a smaller pulley, and various amounts of charge cooling to determine if it is worth it vs swapping out for a turbo. This relies on Mass Air Flow, which I have attempted to calculate by hand with strange results. How do I enable logging of Mass Air Flow Estimated?

Adamw Posted April 29, 2022 Report Share Posted April 29, 2022 Go to >logging>set up logging>PC Logging, hit "Add All" at the bottom. This will add any new parameters to your log set that have been introduced since you have last hit Add All. Quote Link to comment Share on other sites More sharing options...
chickeneatman Posted April 30, 2022 Author Report Share Posted April 30, 2022 RIght, I suppose I should phrase it this way: Currently I am unable to log any data for Mass Air Flow. How do I get the ECU to generate that data? Quote Link to comment Share on other sites More sharing options...
Adamw Posted April 30, 2022 Report Share Posted April 30, 2022 If you are on 6.22 firmware then you should only have to do the add all as I said above TTP 1 Quote Link to comment Share on other sites More sharing options...
chickeneatman Posted May 2, 2022 Author Report Share Posted May 2, 2022 Ah that must be it then. I am on a previous firmware yet. I didn't realize this was a new feature. Thanks Adam Quote Link to comment Share on other sites More sharing options...
Electredge Posted June 7, 2022 Report Share Posted June 7, 2022 noticed mass air flow estimated was not logging... this was a pc log and I installed the newest firmware last friday... and I have at least 3 other Link ECU's currently running on the new firmware all of which did not have this problem, let me know if you want me to send you map and log.

It's always been there, typically we have it setup so that new installs will be logging all the new runtimes so most people never need to touch it But yeah if you log less you can log for longer with less load on the computer Electredge 1 Quote Link to comment Share on other sites More sharing options...
