Default AEM EMS & EVAP System

Does the AEM V2. control the EVAP system?

I made the following post in a different section of the forums, and one of the users thought that the AEM V2 controlled the EVAP system. Is anyone able to confirm that?

I'm working on an install right now and I have a few questions.

Fuel EVAP System:

I have been doing some browsing and it looks like when your running an AEM EMS none of the EVAP system is controlled anymore. I took a picture of this area last night:

Am I correcting in assuming that I can remove the plumbing and components that I have circled? It looks like you're able to remove the entire system up to the fuel tank and then cap those lines. The only thing I'd like to avoid is excess pressure in the fuel tank, but I haven't found a solid way to deal with that problem. Is it really going to be as simple as finding and fitting a venting fuel cap? What are the best (safest) way(s) to block and cap off the lines for this system?

You are correct. AEM doesn't control EVAP system. I removed the whole system on mine. You will have 2 hoses left from gas tank after everything is out. I left those vented to atmosphere. I believe a few others are doing the same.

Or if you want to put filters on those, you can do this,

Hope that helps

AEM says it has EVAP Purge function on the V2. http://www.aemelectronics.com/series...-2000-2003-457
