Seeking feedback, ideas,

 

To install an exhaust brake (EB) with a non stardard method to control the EB.

How?, leverage some functionality by adding micro switches, relay(s), tapping into the vehicle control modules.

This is not the preferred setup and will require the operator or system design to replace the functionality of an electronic control box.

 

Why? I have the brake itself, don’t have the expensive electronics.

Thanks in advance, First Post Ever,..

 

Application:

2002 Dodge Ram 5.9 H.O. Cummins, 6 Speed Manual Trans.

 

i figure a switch and string of micro switches that will turn the eb on/off could be used inline to the activation relay for the vacuum control valve.

 

Proposed Setup

 

Main Switch - 2 Speed Axel Switch on Transmission Shifter

pull to turn on,  provides a ground to a micro switch string, somewhere on the throttle and clutch.

 

The micro switch string will interrupt a Bosch relay, controls the vacuum solenoid for the EB.

when you push on the throttle or clutch, the vacuum solenoid for the EB will deactivate dumping the vacuum in the EB.

 

Ideas, thoughts, what would you do differently?

I had an exhaust failure of sorts.  Going down long grade towing 9k rv and one of the plug bolts in the exhaust pipe came out.  Scared us both when it let loose.  At the time all we heard was a hell of a noise and didnt know what was going on.  Burned a hole in weather stripping about size of silver dollar and melted trans dip stick handle.  Sounded like when you take car thru car wash and the water hits your roof, except lots louder.  After calming down and wife having death grip and the handle of the B pillar with one hand and other hand straight arming the dash, found reason for noise that was louder than chain saw, called our mechanic 600 miles away, left message and he never returned call.  That was beginning of me thinking our mechanic not as good as he was.    Spent night in RV park.  Called BD exhaust place the next day and they explained what the 2 ports were for and just replace the brass plug and put a "security wire" type thing on plug, so plug cant work loose. (At the time I didnt know if any other parts were missing or not).   Most brass plugs have hollow head that I could find, but need solid head to be able to drill hole for wire (and not leak).    Finally found solid brass plug drilled hole in the head and used stainless steel dowl or "security wire".  Stainless steel dowl also better known as bicycle spoke?  When I got a new dip stick for trans, I think I got ripped again.  Dont remember the price exactly, but not cheap.  And wife didnt fall sleep when I was driving for many months after experiance.  

Thats crazy. I've heard of crazy stuff happening but not like that.

 

So you've got it installed on an automatic? You have to do valve springs to put one on an automatic right?

What I was told is my springs are good enough, poundage wise.  Dont remember number but stock is 40 or 60?  I'm under that, but currently in the process of getting plumbing parts to double check back pressure.  Was 8 pounds under whatever directions stated for more strong springs  but that was when installed in 2005?.

I don't think it is about whether or not it is an automatic or a manual - I think it is about whether you have a 12 valve or a 24 valve engine, being the 24 valve engine already has the heavier valve springs.  I think.

Dont know what  your doing or planned.  But if you need anything after installing pac brake has a lot more dealers nation wide.  I choice bd because just hour north of me in bc canada.  But doesnt do me much good when traveling around our country.  And pac brake also stronger, forget which model.  Which has its pluses and minuses.  While mine works great I would go pac brake if doing over just because of the amount of dealers.  Not to mention bd directions are written in French, Canadain and English or a hybrid there of all together.  Not one language then another printed but a jumbled mess.  And when I called up there I  got "out of country" fees on my phone bill.  And their directions are just bd.  I have pac break air bags, also in canada and directions easy to understand.  So not ranting about you Canadain's.  EH?

Im just going off what I've seen listed when I've checked they all say automatics need upgraded exhaust springs and i was only to assume that they put softer exhaust springs in automatics for whatever reason
