Question E-Manage tuning tips and maps

Ok I need some help tuning my E-Manage. Right now, I'm still using the RRFPR to keep the car running, but I plan on taking that out soon and replacing it with 440cc injectors. How do you guys suggest I tune for this? Just use the air flow adjustment map to take out fuel and leave everything else alone? Take out some timing that will be added due to the lower air flow the ECU is going to see? Is there any reason I should use the additional injection map? If anyone has a map with a similar setup, I wouldn't mind taking a look at it.

Here's my setup on a 2000 RS:
VF30 running 5 psi at the wastegate
3" turbo back, no cats
440cc RC injectors with WRX fuel pump
JC Sports TMIC

I have all the E-Manage harnesses and the pressure sensor

If you have the pressure sensor just adjust your AF map based on pressure. The additional injector map is if you have added some injectors to your system. And probably wouldn't hurt to pull a little bit of timing. I have a map you can look at to see some good areas to pull the timing from, but no maps that use a pressure sensor since I have yet to get one.

How can you adjust the air flow map based on pressure? I thought it could only do RPM vs throttle position. And the additional injection map is for adding fuel by changing the duty cycle with your normal injectors, the sub-injector map is for extra injectors.

I think it is an option that only becomes unlocked once you switch to the "Greddy Pressure Sensor" then you can adjust the map that way...

I could be wrong, im still not good w/ my emanage

AR on your tool bar is the Air fuel ratio that adjusts fuel delivery by editing the voltage reading your ECU receives from your Air sensor your actual injectors.

Inj on your tool bar is where you can adjust the aditional duty cycle by pressure. When you click the little blue car and select the greddy pressure sensor you can adjust the aditional duty cycles based on Pressure.

As I said I haven't gotten my pressure sensor yet, trying to get my hands on one right now because I want all my fuel delivery to be based on pressure and not airflow adjustments and the TPS sensor.

PS, as far as we have been able to find, the AR setting is the only place to actually remove fuel.
