Im using the older tactrix cable w/ the cable hack to make it all work but I have a problem. It worked fine when pulled my stock rom out of the ecu but today I got my first base map from 4wstuning who is going to be doing the tune. I try to flash it into the car using test write to ecu first just to make sure theres a good connection but there isnt. It gets through the first three lines of data, something along the lines of ...........(0000) ............(1111) ............(FFFF), then I get an error. It think it said no interaction or something like that. Anyone have an idea what the probelm is?
