I posted over in the 3rd gen section, but got no answers to my questions.

Basically i'm looking for anyone who is currently running over the threshold for the stock map sensor.

Everyone says replace your map sensor with a 3 bar sensor and you'll be fine.

But my question is that i thought the maps (fuel,ignition,etc) only have cells that go up to 17psi on the boost axis. Like i thought the last row or column or whatever corresponded to 1.2 bar, is this not the case. I mean i figure the PFC will work above that, but it would only provide the amount of fuel given for the highest boost level on the map, and thus at higher boost you would run lean. Am i confused??

I figured maybe the assignment of p1 through p? or n1-n? were just arbitrary and that with a datalogit one could change what the cells corresponded to and thus solve the problem by spacing out the cells more or by stealing a cell from the vacuum side or something??

Someone please help!!!

 

The default mapping of p10 to p20 is:
0.0, 0.1, 0.2, 0.3, 0.4, 0.5, 0.6, 0.8, 1.0, 1.2, 1.4 bar

So you are OK up to ~20psi.

And yes this mapping is arbitary and can be changed with Datalogit. (Of course the maps have to be changed at the same time.)

 

Thank you steve, finally an answer
