Running ITB mode backward?
Posted: Sun Dec 24, 2017 4:28 am
So if I understand correctly, itb mode blends map based at low load with TPS based at high loads. This is done for more accurate load sensing because of the way ITB's work so you only have to tune one VE table and Tunerstudio autotune will work when set up correct. Can I reverse the curves so it uses TPS at low loads up to 100kpa "normal off boost" and then swap to map based from 101kpa to 250kpa? It's a fuel injected two stroke that currently runs alpha-n TPS based and I need to add fuel when I add a turbo, so map based would work best high rpm and TPS at low, the oposite of ITB on a four stroke. Can I just reverse the curves and have it work correct?
I can turn on second load source in tunerstudio vs ITB mode and a second table option shows up so table VE1 is Tps vs rpm and VE2 shows map vs rpm, the autotune feature then also has the choice to tune VE1 and VE2 in separate windows.
How does it autotune with two different VE tables? I used autotune with a map based system only with a single VE table and had great luck but that was a smooth 4 stroke not a finicky two stroke with a weak low load Vac signal.
Any info is greatly appreciated!
Thanks
