Wow, Victor, great info thank you. I'll get busy with this advice thanks again.

Thanks Steve, I purchased the Mongoose and still cannot connect too 2 vehicles, a 03 7.3 diesel Excursion and a 99 lincoln town car, but it seems to connect to newer vehicles quickly. Any ideas?

Does anyone have a recommendation for a pass thru device for the NVH to read RPM Speed etc? I originally was able to use my Escan pro, but that has stopped, I tried my Bosch VCI, Flasher pro and my OTC MVCI with nothing working. Any ideas?
