I believe so but I am not a 100% sure. Evo7 has a different rom to flash though, just keep that in mind.

Hi, yes this works on a JDM 7, but it does have a different ROM

Its like having a dashcam for your tune basically.

Are you able to stand-alone log ACD and EFI at the same time with the OP 2.0? If so can you post up your logcfg.txt file? - I've not been able to get mine to work.

Can't log both at the same time. As far as I know openport can open a communication line and only focus on one or the other. But I haven't tried tbh.

I can get OP 2.0 to log EFI MUT II parameters in standalone mode but I cannot get it to log ACD MUT II values. Do you know what command is required in the logcfg.txt file to do this?

Post up your ROM and I will try to get you the right XML definition file.

I've actually never logged the ACD through the sd card. I have logged the efi though.

Try this as a test:

type=mut2
paramname=GForceSensorAcceleration
paramid=0x1D
scalingrpn=x,2,-,64,/

You probably have a evo 7 acd ecu with ayc support. You will need a xml for that specifically.

I tested this today and unfortunately it only logs 0x1D from the EFI Mut (which is Airflow per rev). I will call Tactrix next week and ask their advice.


If I can't log the ACD MUT channels then it's impossible to see the effect of tuning changes. I also tried using my old 1.3U cable with EvoScan 2.9 to log ACD, but since I installed the Tactrix OP 2.0 drivers, the cable is no longer recognized by my laptop. :-(


I tried uninstalling Evoscan, uninstalling ECUFlash 1.44, rebooting, reinstalling ECUFlash 1.44, reinstalling EvoScan 2.9 and rebooting - still the 1.3U cable is not recognized.


Does anyone know if it is possible to log ACD channels with the 1.3U cable?

Honestly, whenever I logged ACD I did it with my laptop directly. Mostly cause I'd hit log right before doing something with the car and then stop log. I find the very large continuous logging files difficult to sort through to find the event I was looking for.

Thanks for responding. Please can you clarify what you use to log your ACD directly? Is it a Tactrix 1.3U cable and Evoscan 2.7/2.8, or is it with a Tactrix OP 2.0, USB cable and Evoscan 2.9?


I'm simply trying to find the right combination of cable and software needed to log the ACD.

Already did all this, I still get the no response from vehicle ECU when trying to use Evoscan.

What i'm thinking is that my PC drivers are no letting the openport to read acd ecu :///
