Hello i just switched to aem on my s13 sr20det. Im using precision 1000cc inj and splitfire coil packs. I also installed the 24 tooth trigger wheel. When i start the car it feels like its running on 2 cylinders. Check all coils for spark, they checked out ok. And all plugs were covered in fuel. Just wondering if this is a timing problem or if i need to switch back to my stock trigger wheel?

Thanks!

You want to use the wheel supplied to you by AEM. You need to make sure your coil dwell settings are in order with what those coils use...

How do you change the dwell settings? Wouldnt these split fire coil packs be pretty much the same as stock coils?

Did you purchase the AEM plug and play unit from AEM?

Then the unit should come with a base map with the correct dwell settings for the factory coil backs in the base cal file...

If not you should get a base cal file from AEM for the Nissan application to work off of to build the actual maps...makes life a lot easier and they pride themselves on doing this...

I just picked up an AEM Series 2 and in the instructions it states to download the base cal file from the AEM website. I'm at work and dont have the instructions with me to give you the exact web address.

I would message AEM they will send you one with setup alrady for SR dwell. Plug and plays come with them, it should be in the ignition wizard section or setup sections

Do you have the correct settings/adjustments made for the 1k cc injectors?
