Hi everyone, Thanks to this fantastic site I've been able to get my streetrod running quite well,not that it's been easy or that it's finished, but getting closer. I'm using a dakota digital dash with a digital speed interface on a 700r4, the digital dash is working great, but I can't seem to get the interface to communicate with the 7730 ecm using $8D bin or get the interface to communicate to the dash that I've built in the adx file. The digital interface has signals of 8k 4k and 2k available. I've tried hooking up the 4k signal to the ecm terminal B10 still nothing. also I'm using an autoprom, and everything else on the adx dash is working. Any insight would be greatly appreciated. Thanks in advance
