Re: Engine communications?
That little scan gauge might work good for what your wanting to do with it. We originally bought a prolink from nexiq. Maybe we had a bad machine, I don't know, but that thing was the biggest pile ever (constantly froze up/ crashed, wouldn't display data, etc). We got so many free trials per manufacturer and we used all the caterpillar ones up on a c7 we were trying to diagnose. I could see spending 150 bucks and taking a gamble on that but for $2,000+ the **** better work. I've talked to other techs and we've all agreed that the oem software on a laptop is the only way to go as for a medium/heavy duty scan tool.
