Sorry, didn't really mean to use such unkind words, must just be bad mood Monday But thanks, you have answered my question....I didn't realise there was so much re-work/re-code required to make those products work for our Falcons. Can you clarify what is currently available re: datalogging, and how it might fit in with this package? Will this support an analogue input so it can log data from a wbo2 controller? I would expect this is key to being able to make use of any Home Tuner package properly... Is there any reason not to expect to be able to modify all scalars, tables, and functions in this home tuner package? It would be great to be able to compare two different calibrations, or at least compare the current calibration to the stock calibration. That would help the user keep track of what they have changed. Would it be possible to attach notes/commentary to a calibration? It would make it easier for a user to remember what they where trying to achieve in different parts of the calibration. Cheers, Dave EDIT: Hmmm, looks like I have a different username on my work computer (black_xr8ute)? Apologies for any confusion...
