Hey guys,

Hoping someone may be able to help, I am currently trying to clean up the tune on my vehicle as the IAM drops at the moment. The issue I am having is when I try log the car there are a few vital parameter's that will not show a reading. I will list what I have logged below and which ones don't work.

A/F Sensor #1 (Not working)
Feedback Knock Correction (Not working)
Fine Learning Knock Correction (Not working)
Engine Load
MAF (g/s)
Engine Speed RPM
IAM
Knock Correction Advance
Learned Ignition Timing
Manifold Pressure Relative
Target Boost
Throttle Angle

The issue here is the most important parameter's that I want to monitor are not showing any readings, AFR Sits at 14.7 constantly, never changes. FBKC and FLKC sit at 0 all the time, which I know isn't true otherwise the IAM wouldn't be dropping. If I try run a MAF recording it also doesn't plot any markers as the corrections not reading at all. I'm using the latest Defs and a Tactrix 2.0, so I am unsure why I am not getting these readings. I have tried only recording a few parameters at a time incase I had to many, since it is recording some parameters i don't think there is a connection issue? It reads and writes perfectly fine. I have looked around the forums and can't seem to find an answer.

Thank you if anyone can help.

Post your rr_system.log.

I deleted the file with RR closed, reopened it and tried to log those parameters, it doesn't seem to matter if i select the normal parameter, (2-byte) or (4-byte)

I have attached my log file
Thanks.

If you log engine speed does it see a change as you rev the engine?
I see nothing wrong in the log that indicates a problem with comms to the ECU.
There's always the possibility the parameter address is wrong and no one every complained about it before.
Does LTV work for you?
What about non-Extended parameters, the ones not marked 2 or 4-byte or *?

Yes engine speed and load etc all work and change accordingly. Its only the correction parameters that don't seem to work. I was originally using the non-extended parameters but get the same error about invalid header when i select them. This error doesn't seem to show up if i don't have fast polling on but it still doesn't change the logs from staying at 0.

This means i can't rescale maf etc as it never see's any corrections.

In the log you sent I only saw the Extended parameters used.
The invalid header message can appear right after you add/remove a logging parameter as the comms has to be interrupted to stop Fast Poll and load the new parameter set to log. The message should go away after the logger clears the line and syncs up again with the ECU.

Has someone modified the ROM to disable corrections resulting in the 0 values?
