It seems to me that when I tried using the P66 V6 XDF on a 93 Fbody ECM one of the VE or SA tables appeared to read correctly (cant remember which one) and the other one was garbage. When using the 94/95 P66 V6 XDF on a 93 Fbody ECM some of the data appears to be correct but not sure if it is, so creating an XDF for the 93 may not be that difficult. Maybe just tweaking the 94/95 XDF can be done. I know nothing about that stuff. In my application I needed more than those 2 tables. The 93 Fbody ECM is the only one that uses the 3.4l with a 700R4 transmission (non electronic). The 94/95 uses the electronic version of transmission. It would have been the perfect choice for my application.
