Ebv

[overl0rd]

Hey everybody, I'm fed up. The EBV on my truck is really on my last nerve. It's starting to get snowy and icy and nasty here in Colorado. The EBV will shut at inopportune moments while I'm driving I.E. on icy roads or what not, and the extra load on the motor slowing it down is enough to make the back tires break loose on the ice, and giving it enough throttle to open the valve again rewards me with tire spin. So, I'm at the end of my rope here, my question is, what would be the "right" way to disable the EBV. I've heard the servo that controls it in the pedestal has oil running through it and just disconnecting it will cause the pressure line to the turbo to leak. I've also heard just unplugging it will throw a code. I figure someone here has already done it, so any advice is greatly appreciated.

There is a little wire connector by the turbo, just on the passenger bottom side if i remember right. Pull it out, my truck never threw any codes, and only took an extra minute to warm up. Best thing i ever did, didn't sound like a vacum anymore with the open exhaust.

OK, Whats an EBV?

Exhaust brake valve I believe. My simpleton cummins dont gots all this dadblamed newfangled fancy stuff on it. Simple power.

Exhaust backpressure valve, its a big butterfly in the outlet pipe from the turbo. Its supposed to help warm the motor up faster to get cab heat faster, but to me its not worth the hassle anymore, as its become a safety and fuel economy issue.

You rally don't notice its there until you open up the exhaust, then you can hear it and it will add backpressure that a normal exhaust has.

guys check out the Mod's section in 99-03 7.3....ramstroker has a wiring trick to turn the EBPV into an exhaust break...essentially he confuses the PCM and has a switch in the truck to control the valve manually.
