AEM settings for DeatschWerks 650's

[turbojack]

I saw below in another thread for AEM EMS tips and tricks.

2. If you have aftermarket injectors, perform the following changes to the calibration
a. Select the injectors from the Injectors wizard under Setup/Injectors from the main menu (See figure A). This will set the proper battery offset for the chosen injectors, but will NOT change the fuel calculations.
b. Open the Fuel map, this can be accomplished by clicking on the Injector button, the Home button, or by pressing ‘ctrl+f’. Once the fuel map is open, press ‘m’ for modify, then select “change injectors/pressure at the bottom of the pop up list. A new window will open asking you to enter the old injector size, and old pressure. Enter the old injector size, and if you are unsure of the pressure, enter 43psi. Then proceed to enter the new injector size, and the new pressure. If the pressure is unchanged, enter 43psi again. This will perform all the fuel changes to accommodate the new injectors. Note: some adjustments will still need to be made.

If I have Deatschwerks 650's, in the wizard which option would I select?



When I'm looking at a default map and I go to "M" "Change Injector/Pressure" what do I enter for the old injector? What do I enter here for the DeatschWerks 650's? Where to I see what the old settings that match below in regards to the existing injectors within the map I'm editing?



Also for the fuel pressure regulator adjustment am I wrong to set this for 43psi and have it hooked up to the cold side pipe for boost pressure reference? Is there another place within the software where I need to make a reference to my FP setting?

are the dw650 high impedence? if they are, you might be able to use rc650cc high impedence(12 or 13ohm) in the inj.batt.offset wizard. not entirely sure this will work, but as long as the resistance is correct, i don't really see why it wouldn't. for the injector/pressure change- old injector enter 577@58psi, if you are using the supplied startup cal for the stock injectors. new injector would be 650cc@43psi.

I have not gotten all the info on the DW but I did find that they spec at 43.5psi, not sure of the effect of 43.5 instead of 43.0

I need to get an email or PM to them so I make sure to enter in the correct info I just assumed this was an easy one to post up here.

Fuel regulator is set at 43 with boost reference. Do I need change something for initial settings letting the AEM know that the FPR is not setup as static and that it has boost reference?

the .5psi won't matter. i would guess that the dw's are high impedence because they are direct fit and the stock injectors are high impedence. however, it should specify on the flow sheet that comes with the injectors. as far as i know, there is no setting to tell the ems you are using a rrfpr, you will just have to tune the fuel map accordingly.
