AEM V2 vvti coils settings
I seem to get asked this alot and it is a little different than the V1 so here is the way to do it.
I am going to use my the numbering system for the coils here that makes the most sense, if you use a different one, you will need to adjust for that.
Step 1.
Wire coil 1 (cylinders 1 and 6) to pin 57B on ecu connector.
Wire coil 2 (cylinders 2 and 5) to pin 56B on ecu connector
Wire coil 3 (cylinders 3 and 4) to pin 55B on ecu connector.
See Post 2 for a wiring diagram to install vvti coils for the aem v1/v2.
Step 2.
change the coil phasing to match the diagram below.
coils 4-6 will be turned off, and coils 1B, 2B and 3B will be turned on and use the phasing numbers shown.
check all the knock sensor boxes unless you can confidently say which one you should use for each cylinder (I know I cant)
Step 3.
This step matters if you are using the distributor as the cam/crank sensor, GTE pickups, or a 7M CPS.
If you are using the GTE style pickups, make sure advanced pickup options look like this picture below, these are the default settings in the GTE basemap.
If you are using the GE distributor, change spark teeth to 24 and try using (Crank H sens below = 2000) and (Crank L sens Above = 1900) as these are the settings from the aem V1.
If you are using the 7M CPS, use these settings and make sure advanced pickup options look like this.
That should get the cam/crank sensors reading right and your coils firing in the right order. Pass it on

Borrowed my diagram from my tt ecu mod thread and changed it to show how to do it for the aem v2 (also works for v1).
Shows the wire to move for the maf pin to the map pin spot so you can reuse the maf wires in the engine bay for MAP and IAT.
This is how I wire the coils, map and maf wires on all aem ems v1 and v2.

I know this thread old but I have a quick question. While on Aem tuner doing this mod would I have to change coil Dwell under wizards ALL CDI SYSTEMS EXCEPT FORD TFI. or can I leave it at Toyota Supra non Turbo/Lexus gs /SC300
Because you said You got your info from SecretSC and he says use this setting. and if I use ALL CDI SYSTEMS EXCEPT FORD TFI SETTINGS WHICH ONE DO I PICK 2MS CHARGE TIME OR 3MS CHARGE TimE?
It's 2 of these in the coil Dwell configuration names.
You don't state this in your thread or the other one with the Ecu mod. Any help is generally appreciated. Just trying to get my sc nat running
