On my 2000, I installed a a/c solenoid for a high idle and it worked great when it was too warm for the parameters to be met. Worked good in summer too for a/c. PM me if anyone wants info about what I did.

Interesting point. I wonder how much difference this makes?
With the Pulse Controller on my Adrenaline I can, and do, read out IAT.
I'll have to keep an eye on that when first starting up... and see what the grid heaters do to the internal air temp.
Unfortunately, for test purposes, we have not yet been cold enough to get into grid heater activity at start up.

FWIW - my experience at 100,000 miles, with fair amount of added fueling, the IAT sensors get pretty cruded up. If you have a 99 and you've never cleaned or replaced it.... might be worth doing. I have no idea how much soot etc. it takes to throw off the IAT sensor, but my guess is, not a lot?

My high idle kicks on around 40 degrees and colder,takes about 3 minutes after a cold start. If I use the block heater and its below 0,my high idle still kicks in.

I would assume it would make a marginal difference on initial startup. Especially after you let them cycle. Then as they are kicking in, it should be warming in the intake charge up somewhat.

My IAT must be reading low then, because my grids have already kicked in a few mornings when it's been in the 50s down to the high 40s. Maybe that explains why my high idle will kick in closer to 32* than I would expect.

My Dealer screwed up the Flash as well! I wired in a manual High Idle Kicker. when I checked the sensors with my Scangauge II all the conditions were being met, but........No Hi Idle. Have to bring it back to them.

do they all come with high idle? if so mine hasnt done it. would be nice to have considering its usually 30 below up here

No - you have to go to the dealer to enable it (that is if you can find a dealer that actually knows how) or buy/borrow a SMARTY.

This one seved me well for many years.



I "tested" a SMARTY at a diesel get together a few years back, now I have the 3 cyl, and High Idle.

Do the '03 have the IAT sensor?

RowJ

Must have, since they still use the grid heaters.... but never actually looked?
On 2nd Gens, it driver side, 3/4 back on the head/Air Plenum. Sticks out horizontally.

EDIT: 'Retirednak' - Must be an Automatic to be getting some computer controlled high idle.
Did a search. 03's have high idle in the cruise control, but needs to be enabled by dealer.
Press 'Set' button to get 1000 rpm
press 'Accel' to get 1500 rpm
Some good additional info here .....

what does the 3 cyl idle do?

RowJ

"...if Intake Manifold Temperature (IMT) is less than -9°C (15°F), and all of the parameters for high speed idle are met, three of the cylinders will be shut off upon reaching 1200 rpm, creating a slight change in engine sound which is normal.
This allows the engine to create increased heat in the cooling system, allowing more rapid engine warm up and faster cab heating."

Let us know where you are. Someone with a Smarty may live nearby and will let you test it.
High idle stays with your CTD, after you return Smarty .... present from Marco (Smarty inventor) for trying his product!

i live in saskatchewan, canada. about 2 1/2 hours north of saskatoon

Finally remembered to check IAT at Startup... when Grid Heaters cycle in!
Saw 15* increase from the grid heaters....on a 30* day. Would this # vary with colder outside temps? Not sure.
Also, this was on a 'plugged in' CTD. Will that fact affect the difference? Can't reason that one out either.....
until after I've had my coffee!

WOW! May or may not find a Smarty up there?? Flew a float plane into Price Albert National Park once, but you must be way north of there....no?
I'd start a new thread asking for any Smarty in your area. Never know?
Might cost you a beer... or a lunch.... but it would be worth it!

What was your IAT reading compared to ambient temperature when you had it plugged in?
