Coolant temp reads -40 with Tactrix SD logging

[ras06LGT]

I went to the track yesterday and set up my Tactrix to auto log to SD card to monitor vitals throughout the day. I had a few parameters set up for logging some things related to boost and fueling, along with basics like throttle, RPM, and coolant temps.

 

After looking back at the logs I found the coolant temps would always show -40 for the values. I did not have this issue before when doing SD logging. I also verified the coolant values are reading normal via the btssm app.

 

Here's the code I'm using for the coolant temp in the logcfg.txt file.

 

paramname = ECT

paramid = 0x000008

databits = 8

scalingrpn = 32,9,x,40,-,*,5,/,+

 

This is a direct copy/paste from the online configuration tool for logging, using the ECU ID A2WF200N (minus renaming the parameter - I tried it w/o renaming and had the same result of showing -40).

 

Any ideas why the temps aren't recording properly via Tactrix stand-alone SD logging? All other parameters logged fine.

I also have the same ecu id and that works fine for me. What does the next line look like?

Here's the whole code. I borrowed it from another member's post a while back on here since it had basically the same parameters as mine, but was formatted a lot cleaner.

Yeah that looks like mine lol. Try it without the IDC parameter(I never double checked to see if this worked). Also try logging just the ECT and RPM trigger and see if it comes up.

[ras06LGT]

The IDC seemed to be working fine once I fixed the typo (paramname was missing the first 'm' I believe).

 

I'll give it a shot with just the RPM and ECT and see what happens.
