I am using the scanner and it works good, but there are a lot of params not in the program I want

In my HS3000 reference book there are a bucket load of
PRN (Parameter Reference Numbers). I have been able to easily pull a bunch of the 1 byte J1979 params, but what hex do I send to the cable to pull a PRN such as steering angle?

I have been using functionally addressed messages, but how do I access the physically addressed params?

CS = Calculated Checksum that my program does.
I tried :
01 01 41 05 6C 6A F1 01 00 0C CS (trying to test on RPM)

DUH!! I just found some basic info on this site. What is the FASTEST way to pull data? High Speed VPW and broadcast in blocks???


Is this right????
