Like the title says, I put my begi fmu on this morning, as well as my bipes acu, the fuel pump in the car is now making noises and my exhaust almost sounds like its misfiring, kinda has a little gurgle to it. Suggestions? I've tried tweaking the fmu but it doesn't seem to make any differences... Afr at idle is right between 14.7 and 15.1. But it's also idling at almost 2 grand..?

 

aside from remove the poop, and install MS... (hopefully you are prepared for the hazing that comes with your question)
make sure you have all the wires going to the "right" wires on the harness, and that all the wires that are screw tightened into the plug are in the appropriate positions, and all the switches in the back of the ACU are set appropriately. be sure all plugs and wires are good, and check for vaccum leaks.
i know its all common sense, but double and triple check everything. and if (when) all else fails, go MS
the fuel pump making noises is kindof strange though. what is it sounding like???

 

I already know the flaming will come, but I got everything for a price I couldn't pass up. It's almost like a vibrating right behind me where the tank is. It started doing that as soon as the fmu was on, before bipes was even wired up

 

So the price of a blown engine was too much to pass up. Nice.

 

Yes exactly
