I’m upgrading my steering Ecu on my 2013 IS 250 and was hoping someone could either lend me a j2534 vci cable or tell me where I can get a good one. Mine is crap and keeps losing connection in the middle of the calibration. I have Techstream working on my pc already. I live in Chattanooga, Tennessee if anyone is local. Awesome forum too, just found it!

 

If you were in SoCal I would help ya out. Good luck 👍

 

T r y one more time and put a charger on the battery. It needs to be over 12.2v the entire time.

But it could be your cable too!

 

are you located in florida , i can help you out with that
