Wrong XDF file, check the TunerPro title bar in the above image. Also note how the entries in that table are foo. Use everything that was supplied with the EBL P4 system.

Re: Memcal Compatibility

Yes, you can use a '7730 MEMCAL in a '7165 ECM. Should either remove the knock filter from the MEMCAL, or remove the external knock filter. Other wise will end up with two knock filters.
