Red Cube flow sensor with Extreme EMS

[mleimetter]

Hi all. I just attached a red cube fuel flow sensor following all the protocols. One instruction I have is for a K factor of 68000. The other instruction says that’s for Liters and not gallons so the K Factor should be set at 18000. It also requires a 5k6 resistor to be jumped between the 5v on the RDAC and the FF1 terminal, which I did. I’m getting a fuel flow reading like 36GPH which impossible with the Subaru engine I have. The FF sensor did not come with a resistor so I ordered some from Amazon. It’s listed 5k6 but the rings don’t match what I think it should look like. My question is, can the wrong resistor be causing the ultra high reading using 18000 K Factor? The K Factor setting on the Extreme EMS only goes to 60000 so there’s no adjusting up for correction.

Hi.

For my Honda engine i set a K factor of 17700. Don't you have a multimeter to check the value of that resistor?

The resister is fine. All kind of conflicting information from both companies. EI says 68000, Michigan Avionics says 18000. At 18000 I get 36 gph. I’m not sure what I’m doing wrong.
