on my dash 2 im using 2 race technology sensors and the rest of the info comes from the ecu, the info from the ecus fine but the readings from the sensor jumps around like mad and its unreadable in the software theres something called filtering is it something to do with these settings???

i'm no expert on race technology gear specifically, but am an expert in instrumentation and datalogging.

it could possibly be smoothed with filtering but hard to say without seeing the readings to know what it's doing as it could also be interference.

what is the sensor and how have you cabled it? have you used a screened cable or a twisted pair?

Do you need to fit the pull up resistors?

NEEDFORSPEED

the pull up resistors are only to convert from a resistance to a voltage, ive not used shielded cable no but this happens with just the ignition on aswel without running so would of thought it will just be a setting issue?? help!

foreigneRS

although the readings are jumping around a bit, are they what you would expect to read? if so, looks like introducing some filtering to the inputs will sort it out

What sensors are they? Could it be an earthing issue somewhere on the dash 2 or sensors? I re-earthed my wideband direct to the chassis and it sorted a similar issue with erratic readings on the data logging side.

As fast guy said, ground is where to start
