Hi all,
Relatively new to this platform (previous experience was in EEC-IV tuning) and trying to initiate a crank relearn on a 2015 5.0 mustang PCM. Engine and PCM were a takeout from a 2015 GT and is now living in a 1968 Country Sedan station wagon. TC-1791, ECM, Ford; Operating system: FRPP1H2 (changed the strategy to a 2015 Control Pack.)
When I attempt to start the relearn procedure, I receive an error "unable to initialize crank relearn routine". This is after the engine is up to temp, etc. I've tried with engine running and with engine off (according to the HP Tuners process
https://support.hptuners.com/hc/en-u...earn-Procedure.)
The performance pack tune has the misfire monitor disabled by default, so I enabled it thinking this may be the issue. No change. No DTCs detected.
Any others see this type of issue on performance pack/crate engine situations? I've searched the web and forums but nothing specific to this scenario.
