PhoSho Posted March 31 Report Share Posted March 31 Howdy All, What is the correct calibration for the Link (Variohm) PS150 Fuel Pressure sensor in the G5 software (running a WRX104X)? I don't see a specific option for this sensor, unless I am just missing it. Any help is appreciated. Thanks! Quote Link to comment Share on other sites More sharing options...

PhoSho Posted April 12 Author Report Share Posted April 12 Hoping someone could help with a fuel pressure discrepancy I am experiencing. I have a mechanical gauge on my FPR mounted directly into the body. Manufacturer (Radium) claims +/- 2% accuracy. I have the Link PS150 sensor mounted on the fuel line directly before it feeds into the regulator, so they are just a couple inches apart. I see a ~30kpa difference between the two (gauge reads around 200 kpa while the sensor reports ~230 kpa) at idle with reference line hooked up (similar without reference). The calibration I used for the sensor is the '1000 kpa TI Sensor' cal shown earlier in this thread. Which one should I trust? If the sensor is off, once I switch to modelled, everything will be off. I have attached a photo of my FPR setup. Sensor is to the left, on the feed line to the regulator. Quote Link to comment Share on other sites More sharing options...
Adamw Posted April 13 Report Share Posted April 13 Does that gauge have a vent on it? I cant see it in the picture, but I wouldnt trust it if it doesnt have a vent. Usually there is a little rubber plug that you poke a pin hole through. Quote Link to comment Share on other sites More sharing options...
PhoSho Posted April 14 Author Report Share Posted April 14 The gauge does have a vent, but it is oddly located on the bottom. I had initially vented it, but that was in the winter. I pulled the plug again and everything is much closer now - within ~5% of the sensor reading. Quote Link to comment Share on other sites More sharing options...
