DET 3 250kpa

Is it possible to alter the fuel map using the inbuilt MAP sensor?

[dan_t]

Yes definitely. Use Analoge in #2 as your Load source and make sure you don't wire anything else into that input.

[Koop]

If you already have a fuel map with TPS or anything else as load source you could use analog #2 as correction for the fuel map. Add fuel as pressure increases for example.
But i would rather use MAP as load

I wanted to do this too, to modify the standard injector signal using the MAP sensor, it seems like it should be very easy to set up and base tune, (0 boost=100%fuel, 1bar boost=200% fuel, etc). Unfortunately it didn't work and I'm now trying the FIT, but still no joy as yet so maybe there's another issue.
