High Idle Mod

[shook08]

Just bought a 2011, had a 2005 with high idle mod loved it, can this be done on the 2011 with upfitter switches.

anyone, yes, no, maybe?

Yes, it is the same idea but the 2011's SEIC requires a resistor to provide a voltage signal to PTO RPM whereas the 05-10 SEIC would work without a resistor/voltage signal.

Do you still need the resistor if you're using BCP instead of the PTO mode?

On page 3/9 of the linked .pdf file: Input Resistor In ALL modes (SEIC, PTO, BCP), an input resistor is required. This resistor value may be obtained per table "B".

Anyone know the wattage of the resistor. The Source had a 22,000ohm resistor availabe in 1/8 and 1/4 watt. Or am I barking up the wrong tree totally?

Idle up is a factory option on the GM's. This is great that it will be a relatively simple procedure to get idle control on the new trucks.

Neat and the fact that I ordered upfitter switches makes this relatively easy... Although hopefully I can find the correct resistor. A neat mod may be to use a rheastat to set the resistance level, this way you can SEIC at whatever RPM you want at a given time. Rather than limited to just the one level of a single resistor.

Where the instruction say "POT" that is short for potentiometer, which is also known as a rheostat.

If I just want to hook up SEIC is it just a matter of wiring the SEIC pass through to the Upfitter switch I want to use with a resistor separating them? Or is there more to it?
