FIXED Power FC (ap engineering) map sensor upgrade - how to do it right?

[johnch]

Hi,

 

So got all the stuff sorted on our sc300 2jzgte swap.

Single turbo injectors, cams etc etc.

We are running a AP engineering power fc with harness to work on the no vvt 2jzgte engine.

So with everything plugged in using the stock map sensor all is well but obviously limited to approx 1 bar of boost - while we need to get to about 1.6.

Researching the way to go about it I opted to just get the apexi 3 bar map sensor and just in case the optional harness.

I am very familiar with apexi and their D-Jetro versions but mostly on Nissans and Subarus which all are pretty simple to setup.

With this motor I have never used a PFC before.

Using Datalogit for adjustments of scale and offsets for map sensors.

I cant get the car to start with just the apexi map sensor.

 

Things I tried and results: (some things I tried just to try and cover all the options possible)

1. cutting the wires off the stock map sensor and connecting the apexi/denso in its place. Selecting the APEX option in map sensor selection area in the datalogit . Boost control kit option DESELECTED. - Car wont start.

2. cutting the wires off the stock map sensor and connecting the apexi/denso in its place. Selecting the APEX option in map sensor selection area in the datalogit . Boost control kit option ENABLED. - Car wont start.

3. Stock map sensor in place and Apex sensor connected to the boost control kit plug on the PFC. Normal Map sensor selected in datalogit with boost control DESELECTED. - Works fine.

4. Stock map sensor in place and Apex sensor connected to the boost control kit plug on the PFC. Normal Map sensor selected in datalogit with boost control SELECTED. - Doesnt Start.

5. Stock map sensor in place and Apex sensor connected to the boost control kit plug on the PFC. APEX Map sensor selected in datalogit with boost control DESELECTED. - Runs very rich.

6. Stock map sensor in place and Apex sensor connected to the boost control kit plug on the PFC. APEX Map sensor selected in datalogit with boost control SELECTED. - Doesnt start.

 

Did I miss something? am I doing something wrong? Check apexi map sensor and it seems to be good but tomorrow bring in another unit of my personal s14 which I know is good for sure to check.

Anyone with a a PFC and a non factory map sensor?

Any help to allow me to get this car boosting to where it should be is highly appreciated.
