So I went on line and got scammed on a Launch scan tool. Nothing wrong with launch as long as you buy from the US. Yeah China got me. Anyway I really know better Ive always lived by the buy once cry once so Ive found Autel MaxiPro MP 808 for 600 bucks or go all out for 200 more on the new two month old new data, Autel 808 Z-TS. Reason is I have a 2012 Dodge 1500 4x4 that I believe is having injector problems. I need to get into it and see what the pressure's are. It has a slite miss to it and not throwing cel. Anyway the old version should work just fine I think, but then the wife goes and buys herself a 2017 Corvette loaded with bells and whistles makes me thing maybe the new data. I think I've already answered my question. But what do yall think?

OBDLink is the best I've found.

I have that and cant monitor injector pressure.

 

 

Is there a test port on the rail?

I believe there is. Its raining cats and dogs here I'll confirm in the morning.

 

AlfaOBD can do a lot of functions paired with the OBDLink MX or MX+

Remember it's easier to use a test port with a pressure gauge than rely on an electronic sensor which could be misreporting pressures. Keep in mind only 10% of vehicles have a fuel pressure sensor that can be read on the OBDII port. Kind of like our MAP sensor for boost reading which kind of close but not the same reading.
