Does anyone know the real differences between $51 VS V6 Auto Variants, if it just says Serial Data Fixes or Can Purge Fixes does anyone know what actually got changed or this all the info anyone knows?
Also the original memcal in my car which was BPYR was made for 2 wire o2 which mine has, all memcals after this are for 4 wire o2's which looking in tuner pro BPYR vs BRHP there is quite a bit of difference for just heated o2 changes, i can't see heated o2's making much difference to the memcal tune.
$51 variants fixes?

Re: $51 variants fixes?
Ive never looked too closely at the $51 bins, but in 11B to 11C it was as simple as a counter reset for injection events. The serial data fix may have been adding/remving a bit or byte from the stream.
