High Idle or Exhaust brake... what is more effective?

[GWBourne]

well? do you think just letting my exhaust brake do its job for a couple min or do you think the high idle feature would work better?



one saves a bit of fuel and is already paid for...



the other requres more money and work...

You already have the brake. Enable your high idle and go for it. It is a completely different truck for warm up using the high idle and the e-brake. When it is cold enough the auto high idle works great too. When I park my truck I turn on the e-brake, then when I use the remote start I get high idle (if cold enough) and exhaust brake.

I would say the exhaust brake would work. It should already high idle itself if its cold enough and all the conditions are met.

 

[GWBourne]

ehh, you guys are right, it should high idle on its own for a bit, but im talking about high idle via cruise... .



will it high idle and thing its still ideling(with the cruise setup, or with the "dang truck, its cold out, idle faster") letting the exhaust brake be on?

I certainly will do that uo to 1100 rpm's (mine anyway). If I notch up the rpm higher than 1100 with the cruise button the jake turns off.

good to know... so if i can get the ECM switched on for cheap/free then ill end up spending the 10 dollars for the plug...

Both work great. Although it only drops down to the high 40's - low 50's here, high idle with the exhaust brake brings the engine up to operating temp in no time.

 

[GWBourne]

yeah, it has hit low 40's to low 30's so far here... im new to this area... NOT a snow guy at all... matter of fact, i have to buy another winter beater so i can drive in the snow as my 2wd cummins does NOT like wet roads let alone icy roads...



anyway, i still want to drive it once or twice a week when the roads are nice. just bought a block heater cord, and got it put on, am in the process of wiring in some new switches in the apartment. . hope they dont mind.



i still want the high idle for when im at work though. talked to a dealer today who is cool with me having mods so long as i dont try to bring it in for something i caused. not like the cali dealers who will void my warenty in to time flat...
