Hi to all !!
Have only been using HP tuners for a few months now and its been a very quick learning curve !! I have a couple of quick question to try and get my head around how this software works and try and figure my problems first before i post up some tuning logs and files etc .
1 : In the EQ open loop table can you command a lower ratio than 1 in the low map { say 40-60 kpa } range to lean out cruise AF ratios ??? Ive tried changing the numbers but they dont respond in the scanner when logging . I can get them to change going above 1 before PE engages for a smoother transition or part throttle overtake etc but not below .
2 : Ive tried every effort to enable the lean cruise tables but have had no luck { yes its an AUS based platform ECM } the only thing that slightly happens is that is does lean out but only at a higher than commanded rpm range approx 500rpm but this puts my cruise speed to high .
3 : Ive also discovered that I can change OS systems to take advantage of the RTT features but under my OS tab in editor I have a blank page which apparently means I have a custom OS {not sure what that is } and I need to re flash back to original to enable those functions ???
Ill leave it at that for now except that this is a Mafless SD tune .
Bit of a back story to this vehicle / tune which i can explain but dont want to complicate the thread.
Any questions please ask and ill try to figure the tune/logs uploading in the meantime.
Cheers Carl.
