04 Escallade Efans settings

[aknovaman]

Imported setings from 2002 camaro and no luck so can someone email me a 04 Escallade settings for efans. Should the AC recirc be set or set to 2 fans. One fan comes on with AC turned on and also when engine gets hot. Other fan relay just clicks.
Thx,

An '04 Escalade should have the thermostatic clutch & engine driven fan so any e-fan settings within the PCM should all be disabled (since you don't have e-fans). How did you go about adding e-fans to this Escalade? If one relay just clicks it sounds like you may be dealing with more than a tuning related issue. Fan wiring all hooked up correctly?

More info. Added LS1 fans to the stock radiator, built a dual relay harness similar to factory 2002 camaro schematics. Tested relays by grounding wires normally going to PCM, from pins 33 and 42 and both fans operated. Started engine and turned on AC, only one fan operates. Let engine rise to 200 degrees and same fan operated as commanded in PCM file. Used 2002 camaro settings in PCM file. So, does AC recirc need set in AC tab or should it be set to 2 fans?

I used to have LS1 fans cooling my 5.7L Sonoma, and from the factory LS1 fans are wired up in 6volt series for "fan 1 low speed" and a relay switches the circuit to "fan 2 high speed" which has the fan motors in parallel for full 12volts. Is this similar to how your fans are wired? Can you post your tune?

I used a 3 relay setup emulating the factory 2005 Silverado circuit. Copy over the fan settings from a 2005 Silverado and set RECIRC to fan #2. and Fan system to 2 FANS.

Will give that a shot. Thx.
