if you drop below 11-1200 the pump has a hard time keeping fluid where it needs to be. when you get around 800 rpm you will be looking to turn it off or it will stall. it's like stoping a stick with the clutch not in.

Yeah I know I just wanted to use lighted so I know when I have it turned on. So there for I don't know witch lighted switch to get if it can even be done. I did get a normal toggle switch plus a dpdt for the ebpv brake.

Jody at DP can program anything you want or need. All you have to do is ask and he will deliver the program you desire. I have recently had my trans built and I am very intersted in the TC lock-up because it will drastically reduce the amount of heat put into the trans. when towing and on long up inclines. Also, the exhaust brake because of the extras I put into my trans. to enable the exhaust brake to work without damaging anything. I hope to get this mod done before the weekend. Well it certainly sound easy except for locating the correct wire to tap into. I have yet to look under the dash and try to find the majical wires. Does anyone have more detailed instructions on the location of the TC and exhaust brake wire locations?

as much as I love DP tuner..I have the SP diesel tc/lock exhaust brake..you set it while in any tune and for get it...you turn it on and off and set lock up and un lock speed using the cruse buttons..you can make it lock and unlock down to 25 MPH...and the brake turns on and off with the go peddle...once I start my truck. I pick my tune..hold the CC on button for 2 seconds..the brake and tc lock is set..when I hit 25 MPH the t/c locks..after up to speed..let off the go peddle and the EBPV will close and slow my truck down to 25 MPH when the tc unlocks so I can come to a stop...when truck is warming up in the am..I can hold the CC for 2 seconds and EBPV will close and aid in warm up..after you hook this up and set your speeds..its just a matter of turning it on when you start your truck in the morning then not touch it till you shut down..just like a jake brake in the big trucks..turn it on and for get it... its so easy..even a caveman can do it..
