Default Aem methanol kit

Hey guys, my aem methanol system has been giving me trouble lately. I remedied the issue of the line popping off of the nozzle, but now my methanol system throws an open circuit code when it has to jump from almost 0 to full spray. If I ease into it to make it reach full spray I do not get the open circuit code. I have the 30-3100 I believe which is a progressive system anyway.
I have changed to a large gauge wire and soldered all if my connections. Could it be a bad pump? Thanks in advance for your help!

Try emailing AEM themselves? They could give you the best answer

Sounds like a controller circuitry error. I would call AEM. As for the nozzle popping off, are you using quick connect fittings?

The whole setup came with nothing but the quick connect fittings!

The quick connects should work really well. Does the little end piece move in and out freely? If you insert the hose into the nozzles quick connect (does the nozzle has the built in check valve on the aem kit?) can you pull on the line and it comes loose? It almost sounds like a faulty connector. Can you post a pick of it?

When I insert the quick connect it does not come loose with a tug, but when the pump hits it's full pressure it will pop off and I would see it run way over because I have the 1000cc monitor. But that is no longer the issue, now that that is fixed I am getting the open circuit code if it slaps full spray right away. It doesn't throw the code if I slowly bring it into boost it works fine.

Without seeing your settings or wiring, and assuming everything is installed correctly, it Sounds like a controller error. I would contact AEM or the distributor you purchased it from and let them know the logic board is faulty.

I would assume that the wiring is correct as it works until it has to go from 0 to full blast relatively quickly

Just a little update, aem has not even responded to my emails. I have sent 2 so far with no response. I just know in the future to go with a better brand.

They use Shurflo pumps, which are rock solid. The controller doesn't seem very robust to me, just my opinion though. The controller is pretty easy to take apart, I'd do that and check that the board isn't messed up. Mine got wet or something and corroded and stop working.

Here's a terrible blurry pic of mine that you can almost see the corrosion Im talking about.



I'm going to use either a pressure switch to the turn the pump and off, or use Carberrys new controller.
