Hope this is the right place, this is my first post.
I have a cheapy OBDII dongle, and ELM327 I borrowed off a mate. I looked up the info and there seems to be clashing information on whether or not it works for me 98 VT Holden 3.8. I can get the TorquePro program on my phone to connect to the dongle but I cannot get the dongle to connect to either the old NOR new ECU I want to install. I went to Holden and they pretty much stuck their thumb up their bum and said "We have no idea how to do that, $88 please." I've also been told the VT needs to be connected with an OBDII interface because just changing them over won't work.
Anybody know how I can change this bloody ECU!??!
Oh, and hello, I'm Liz.
