I tried to run the 3 bar that's for my apexi avcr and I am having some issues. I setup the scale and offset to what others were using for there apexi 3 bar. After doing that the car really doesn't want to idle and when I give it some gas it wants to stall but catches its self last min. I messed around with the offset in option 1, go it to idle but the readings are way off. Anyone run this 3 bar or have any ideas?

 

No ideas?

 

If you calibrate your old and new map sensors, you should be able to determine which part of the map is now being used for idle as compared to before.
All you need is a regulated air pressure source, laptop, and DATALOGIT.

Unless the new map sensor puts out the exact same ABS pressure values
as your previous one did, or you change the settings 3 ABS P values with the DL,
the whole map has to be retuned.

Why?

If your PFC idle PIM ABS pressure has changed, then the P row used for timing and fuel will change.

Or just retune idle and cruise as you will have to retune the whole map
unless you change the SETTING 3 PIM ABS values to corrrespond to the stock values by pressure.

If this does not make any sense to you, find a good tuner.

 

I understand enough to make sense out of it, thanks.
