Default AEM Meth spray controller leaking

Hi Guys!

Just thought i would post here. Been having issues with knock, finally found my AEM controller randomly cutting out mid WOT! Scary shit. Finally got around to testing it and it's leaking pretty bad (used 25psi) so i have just emailed AEM.

anyone else had this? Also i am lucky it happened mid tune and we were safe tuning and i noticed the knock. Anyone non the wiser or fully tuned on high timing could have ZZB

Kinda scary. I will probably throw some Ethanol in tank as a safety precaution.

Yeah a fail safe for sure anytime aux fuel is needed for octane or power. I'm looking into the AEM wide band fail safe to trigger the Guardian Angel in the event of a lean AFR. It seems to be the simplest way to do it.

Yeah. I assume the standard outputs wont cut it because as far as the controller is concerned you are not at full boost( even though you are). Because we kind of tuned around the fault without realising it didn't go too lean. But bats started too increase again and got small knock but sometimes as high as 2. So we kept dropping timing moving things around. It became frustrating for my tuner. A little dissapointed too as reading online sounds more common. And i am overseas so will be without the controller for probably months while they fix.

Small update. AEM are replacing the controller under warranty and sending a replacement. They answered very quickly and i am happy they are sorting this out for me.
