FMB130 & OBDII "Short Fuel Trim" (AVL ID 33)

TELEMATICS

Hello to all!

I run into the following issue and I hope someone can help me.

I have an FMB130 (FMB130BSXW01) running the latest firmware (03.29.00.Rev.18).

It is connected to a Vgate iCar Pro OBDII dongle and I get readings from all supported sensors.
The numbers are OK, except from the “Short Fuel Trim” (AVL ID 33).

While I would expect values from -100 to 99, I get values in the range of 240s.
Here’s a sample from the readings in GPS Server platform.

The obdinfo output is the following.

Prot:5,VIN:N/A,TM:30,CNT:13,ST:DATA REQUESTING,P1:0xFC3EB011,P2:0x80040001,P3:0xC8008001,P4:0x8000001,MIL:0,DTC:0,ID1,Hdr:86F110,Phy:0

That, according to OBD 2007 Pid Reader, means that both 0x06 and 0x14 are supported.

I also checked the dongle with Torque Pro application and the “Short Fuel Trim” is shown correctly.

Any clue on what I’m missing?

Thank you!

Hi @McGyver

Good day, it maybe an issue on parsing kindly check with your developers regarding this.

Once confirmed that there is no issues from your server, and the issues happens again, please contact your sales manager to help us analyzed the issues or create an HD ticket.

Thank you very much @Maynard.

I got in touch with GPS Server and it looks like there was indeed a parsing issue.
They made the necessary updates on their side and it looks OK now.
