OBD-II Scantool

[Dreher]

Recently, there have been a couple of posts regarding DTC's and scantools or software to retrieve info from our vehicle computers. I have an AutoXray EZ-Link OBD-II scanner. I paid about 350. 00 for it including cables and programming for OBD-I vehicles (82-96). Models with only OBD-II programming are under 300. 00.
When I bought it, I could only read and reset DTC's. I downloaded an upgrade from AutoXrays website and can now access some additional, limited info. The active parameters are vehicle speed, intake air temp, RPM, load value, PTO status, and throttle position. Last week, I emailed AutoXray and was told they are working on a Chrysler Enhanced OBD-II upgrade that may enable more parameters.

The only Dodge/Cummins I have tried it on was my 96 12V. Because OBD-II was designed for computer controlled engines, there may be more info available on a 24V. If anyone in the Seattle area with a 24V wants to find out, drop me a line.

Here's a link to a good report from the EPA on scantools and OBD-II:

RA,

Larry Q tried a scan tool last year. He said it was a piece of junk.

My neighbor has some sort of scan tool and he says it is supposed to work with both PSDs and Dodge/Cummins. He's a diesel injection mechanic. We've talked about hooking it up a couple times but we're both so busy we don't get around to it. He says it will do cylinder tests where it will cut the injector on any specific cylinder and monitor RPM drop. Sounds pretty cool. Maybe I oughta take him a beer and say "let's play with this thing!" I want to try it out anyway because I seem to have an intermittent boost module problem where I notice significant defueling at 25psi & max out there. It used to rocket unabated to 32psi. I am hoping it will give a reading for the MAP sensor and I will know if I have a boost module related problem or something else. I will post results after trying out the scan tool.
