WRX_555 Posted December 20, 2023 Report Share Posted December 20, 2023 I’m going to be mapping a Version 3 Impreza STI GC8 on a Link G4X plugin and I’m keen to use the MAF as the load axis for the fuel table. I noticed that the MAF output can’t be used as an input source for the fuelling equation so I just wanted to check if using the MAF voltage can be used as a load axis, with the fuelling equation using MAP.

Adamw Posted December 21, 2023 Report Share Posted December 21, 2023 Load source should be set to off for MAF use as you are measuring the mass directly, so the ecu does not need to know/calculate density. Having said that, I suggest you stick to speed density for most applications, MAF measurement isnt particulary good during transients due to the inherent lag, most OEM ecu's will have a speed density type calculation in the background that overrides the MAF measurment during transients, Link and most other aftermarket ECU's dont have this functionality. I would only use MAF for logging or in applications where operation is relatively steady state such as aircraft or cruise boats. Quote Link to comment Share on other sites More sharing options...
