Good Morning fellow tuners!
I have a few queries that need clarifing regarding a return thread posted for my sake by Hilly (many thanks). I would normally do a PM to the authour but then nobody gets to experience the answers which may be of a benifit to to some, so Hilly this first question is regarding the method that you convened to me regarding set up and operation to gather more hits in the idle section of the histogram. The recomendation for this section of the V-tune is below.
" 1 Engine warm lower the idle to 700rpm and run it on the sidestand and capture as many of the idle cells you can watching the engine temp, a fan can prolong this but you are only after the very top right of the map so it happens quick, use tiny little throttle movements while watching the histogram, you get the hang of it quick because you can see what you are doing. "
My query is (referencing the histogram pic), does this appear to be sufficient data to combat my earlier deficient V-tune runs? I understand that we need to collect more hits to the right (increase TPS hence MAP data) but as you can see with small throttle movements, the trend is to increase RPM (naturally) without any noticable gain in MAP data, am I missing something? the instructions are pretty straight forward, but I am certain that there is not enough data spefically reaching for the < 80kPa MAP's.
I am reluctant to recommence the V-tune until I can nail this. As we all know (now we do) that correct data is required to set up the most important tables, the VE tables.
I should add here that after further knowledge gathering (reading manual) and reviewing various tables from my V-tune runs, comparing (3D application) against the tables contained within a MT8 Cal file Ozroder emailed me ( a sincere thank you for this), Hilly's words of "need to do a bit more here" ring true and are very generous.
