Bringing my question over here from this thread

http://www.3sgto.org/3000gt-stealth-...logging-3.html

I have a Black Stealth LCDBC and it's plugged into the OBD2 port in my ECU adaptor harness. Will it hurt anything or make inaccurate logs if I plug the Tactrix in the port on the dash and run the LCDBC on the port in the adaptor harness and use them at the same time?

Antero, I have a 95 NA car that I did a TT AWD conversion to and it still has the NA ECU wiring harness in it so it has the 1st gen ECU plugs in it. I bought your old adapter harness from you that has a OBD2 port wired in. Well since my car is a 95 it has a OBD2 plug on the dash also so I have 2 OBD2 plugs in my car. My question is can I plug the Tactrix cable in the other plug and data log via SD card while the LCDBC is still plugged in?

Edit: BTW I'm not sure it matters but I have a 98SL flashed ECU.
