Hello Everyone,
When going through the steady state ignition tuning on a turbo car worked example there is a part that I am a little fuzzy on. I understand the concept is very similar to the process for a NA engine. The part where I am getting hung up is in the video when Andre gets to the low RPM areas where you can't make enough boost to access the higher load zones. It looks like the values from the load zone you are able to access is copied across and then it looks like he is following the trend from the lower load zones and reducing the advance as he moves up to the peak boost. I understand that when driving the car you will not be able to access these areas. But for the sake of complete and smooth MAP this should be done. When the video speeds up I am getting lost as to what trend he is following when copying the values across from 4500 they are dropping into the negative values at around 1500.
My question is, when you get to the areas where you can't access for example at 1000 RPM you can't necessarily access the 110 kpa zone and above. Would it be possible to high interpolate this trend from the last tuned zone to the untuned areas to make the map smooth? So in the case of Haltech highlight the 100 kpa zone at 100 RPM up to 200 kPA and linearize it?
Best,
Tom
Your on to the right track Tom thats is what i do also
