So I believe I followed your getting started correctly, however the current tunes I pulled
don't have the vin numbers. Same on both computers [MPC-185 & MPC-197]
Pats code looks like it came in ok
Copyright Tag came in
but the hex value for the VIN is all FF FF FF

The computers are not in the original car so I don't have any other pats related buss items
I did wire the odbII port [16->2], [15->10], [13->13], [12v->16], [gnd -> 4,5]
my old crappy odbII reader pulls a couple codes about fuel but the vin number is blank in it also.

Before I go further I wanted to check if this is an indication of something being wrong.

When I saved the buffer to file it did write the same size file as your instructions 262,144 k

thanks for any input.

Nope thats perfectly normal on the marauders they dont have any vin numbers in themnor do they have any custom pats code as they are E-Pats.

Great info. Not that it matters for me but strangely the 185 has blank pats code but the 197 pulled a pats code.
Moving on (: as time allows.
