Should mention.

I use 4 x custom maps over this as well as the Lambda base fuel target 1 table.
NOTE: the default smpm and baro multipliers are NOT used as they are a bit too basic in application so set these to 1.000
  • *equivalence ratio multiplier
  • *map multiplier
  • *bap multiplier
  • *map/tip multiplier
This way its really easy to do a target fuel change, simple and quick.
Car can be run at any altitude and be fully corrected.
And it works with ITB perfectly.

Makes very easy to calibrate, can do it in NA form, hook up the intake pipe and boost away.
You do need to know what your engine type looses in terms of air flow when the pressure differential across the engine changes (its not the text book function sadly) but its not too hard to work out either. The rest is simple maths.

Just an early version/example of calibration on the new OS3.15lt engine using the above method. 20% TPS to 100% TPS, and various custom maps, sounds complex but in reality its very simple and works fantastic :)
