hey mach, just an update (and for whoever else is reading), just updated to Beta 4.5.117, and found the data freezes a little less, but there are times where the channel data does not match the graph data, which is not good. but having said that, it sounds like you are definitely having some setup issues, not to say the Editor or scanner is 100% perfect, but there are some MAJOR differences when comparing ford (especially eec-v) tuning to GM tuning. there can be alot of variables with what you see going on with the data and what is actually going on. hopefully you know the difference between your commanded Lambda (AFR in base table "in open loop") and Lambse (commanded equivalency ratio) in the scanner. when you are lean, Lambse (mistaken for STFT) will actually command a rich value to try and get your fueling back to what your commanded LAMBDA wants to be, but that isnt your commanded Lambda. its the ecm commanding a value to get you back on track (in layman's terms). it directly correlates to the percentage that your fueling is off compared to your desired Lambda value. thats why having a wide band is so usefull (when you can log it). now when you reved it and it got rich, that depends on what your desired Lambda value is, at that Load (PER-LOAD).it may be something completely different when the engine is loaded. Hopefully im not confusing you or offending you, but if you are coming from a GM background (as do i), it may be helpful to read about the EEC-V strategy. Its actually beautifully simple in a way. similar to Holley EFi if you like to tune in Lambda scales. if i were you, id disable all my closed loop parameters and set all my closed loop requirements low so you are always in closed loop, and set your base table to 1.0/Stoich (14.64:1 or even 14.08:1"true stoich on fuels with e15) then drive it and recheck your MAF transfer to STFT. still not sure what your mods are (boosted, cam, headers,e85,etc) but with 80lb injectors im sure its something worth the need. if you can check your wideband vs that, you may find what the issue is be it injector data or maf transfer. also, with injectors that large, your idle can become pretty unstable if the correct pulse width value isnt used. there is not alot of good info out there on these PCM;s, but if you hav the time, check out (efidynotuning.com) alot of good info on the ford strategy. and if im not mistaken, i believe the 99-02 EEC-V has a ceiling for the injector slop data at around 54LBS. you will have to make up for it in MAF hardware/ tuning. 03/04 EEC-V have a limit of 60lbs. the PCM cannot process any data above that.
