They no longer have the 3 cylinder high idle that was on the 24V's. But the high idle can be enabled. Usually the dealer will charge to do it. However if you can find someone with a Smarty in the area, they can put the high idle feature on for you.

Question, I have a Smarty CR, I'm running it on 60 HP w/timing (Thanks Diesel Nut), can you set the software so that the high idle feature is on with this?



I'm interested in twins, I've been reading a lot of posts here-where is another way I can educate myself? I would kinda prefer (also for money reasons) to go to some people here at TDR for parts-who are the people here who have them?

The automatic high idle is already there and working. Be advised that it can take several minutes to kick in, even in very cold weather.



The one that has to be activated is the manual (on demand) high idle using the cruise control buttons.

there are two different high idles here for the common rails. There is the cold weather high idle that raises the RPM's to around 1000 RPM automatically when the ambient temps are low as well as the engine temps along with a few other parameters that the ECM is reading while the truck ahs been sitting idle for a while.



Then there is the high idle feature that you can control via the cruise control. On automatic trucks with this feature, all you do is turn the cruise control on, hit set, then raise the RPM's with the increase speed button and lower it with the reduce speed button.



The cold weather idle feature is enabled from the factory and works automatically when the time comes. The high idle feature that you have full control of has to be enabled by either the dealer or in the form of some other type of ECM update.



The main reason I mentioned the Smarty downloader is because it has all the factory updates, including the high idle feature. Once you load any of the Smarty performance programs into the ECM, then return it to stock, the ECM has received all of the current updates, including the high idle feature. So at that pint if you have an automatic truck you are good to go. If you have a stick truck there is a pin on the ECM that you need to ground also to make the feature work.

My 07 will ramp up the throttle to 1,000 rpm if its real cold then it it sounds like it drops off a couple cylinders. It sounds like the 3 cyl high idle that my old 01 had. When i touch the brake peddle the motor smooths out & idles down. Are you sure they know longer have the 3 cyl high idle because mine acts like it does.
