Mopar1973man high idle questions

I recently installed the mopar1973man high idle kit and it has worked out great. But i have noticed once I turn it off and let the truck idle for a while it will idle up again to 1200 rpm. It this normal after having my 2001 flashed with the smarty due to it being programmed into the system now. I live in clearwater florida and the days i have noticed this have all been above 70 degrees. Do you guys and gals think I have an issue, operator error, or just part of the new system flash. Any help as always is greatly appreciated. 

2001 2500 quad cab shortbed

24v cummins

47re tranny

6 inch lift with 35x12.5 tires

Totally normal. Once the mode is triggered and the switch is turned off. The ECM software is still flagged for that mode of operation till 165*F of coolant temperature is reached. Then the high idle is canceled. The other way to cancel is to turn the switch off. Then shut down the engine for 10 seconds to 15 seconds and restart. Then the high idle mode is wiped out on a fresh reboot of the ECM.

Be careful if you trigger 3 cylinder mode it will continue the same way as well. 

I try to stay well away from that mode. Way to warm here for that! :)

Hey do you know where i can get soft tranny cooler lines like you used to have in your store?

So the high idle switches are discontinued then? I was planning to get one just to save wiring time tricking the sensors...

They were talking about a soft transmission line set that used to be available the @Me78569 used to make. The high idle kits are still available.

Ok good. I must have misread. I gotta get one of those switches soon. The quad high idle is nice and all but linking up, syncing etc etc it takes a while to get into the truck and some times when it’s super cold I’ve noticed the IQuad module has a tough time connecting

 

 

I found where the cooler line was talked about lol I totally missed that.

 

another common option for the cooler line is also getting NPT to barbed fittings from any hardware store with a 1/2” outlet and running 1/2 “ lines either direct to the cooler or splicing into the metal lines with a compression to barb fitting. Also if you bypass the heat exchanger under the turbo you’ll drop a good bit of trans temperature usually. It helps the heavy haul people, I noticed a 30* drop in temp empty on mine and customer rigs and 60* towing heavy on mountains. Just watch the routing that it doesn’t touch the frame or something sharp but it’s easy to do. You can also plumb in an extrernal hydraulic filter too just make sure to put a bypass in if the filter suddenly clogs so you don’t loose cooler flow or get a head pressure build up in the cooler line. It’ll burn the converter before you know it’s getting hot. I’ve never personally had one do that but I also build up each unit I’ve done it to, filter was there to capture converter build particles and anything that goes threw the system from clutch packs to keep it clean and valves functioning properly. Point is the rubber line thing makes it much easier to deal with and gives a lot of options
