How to shut off EGR with tweecer

EGR Switch Type Scalar - Values

0 = EGR is working and accessing its tables (DEFAULT)
2 = EGR is disabled and bypassing its tables

Thermactor Present Scalar Values - (A.K.A. Smog Pump/Air Pump)

1 = Thermactor is present (DEFAULT)
0 = Thermactor is disabled

Gracias Chris, its wierd how some things you put a 0 to turn it off and some a 0 means it on, lol.

This did intrigue me as to why EGR off isn't '0', so I did a little research...

I think that it probably is intended to always have 0 as 'off', but I'm guessing that in this case, off (2) was added as an afterthought.

In the GFUB strategy doc's listing of the strategy evolution, it says (p. 1-11):

Add a third position to PFEHP; If PFEHP = 2, disable EGR strategy.

(PFEHP is the PID name for the scalar "EGR present")

Perhaps the other 2 (0 and 1) were already used in past strategys without having #2 (off) an option, and to avoid confusion, they didn't change the values around to make 0=off in this strategy. Or maybe they had already coded the other values in, and to avoid having to change completed code, they just added the '2'.

FWIW...
