      My 11" fans are rated at 18 amps each for a total of 36 amps. That is to much for the C6 controller unless I ran 2 of them. I think I will give the Derale pwm 16795 kit a chance with a power relay to the unit controlled by the ignition voltage.

      I think my fans pull a lot of amps also, I have to check. The reason I want to go with the C6 setup is I need to set up a 1D table to raise my idle at high fan load. I can't do that with the Derale because no input in the HP for PWM. Using the C6 would already have the PWM info in the HP for the table. I am just worried one C6 is not enough. Plus I need the A/C trigger for the fans (trinary switch you guys are talking about I guess?)

      On another note, is the A/C idle kick in the HP just a temporary couple second kick or is it constant? If it is constant then I might stay with the Derale, or figure out how to run one fan on the derale and one on the C6.

      I set up a 1D table to raise the RPM when the A/C kick is enabled, based on IAC offset % and coolant temp. Also based on low RPM drop.

      I will fire it up tomorrow and check my settings.

      I have a LS3 based 427 motor and when the A/C kicks in you cannot tell rpm wise. So that is not an issue for me. Now with the cam and all, my motor idles at 800rpm so that might make a difference.

      I setup 1 advanced table for A/C kick and 1 for below 700 rpm to open up IAC based on coolant temps to keep it from stalling. We shall see when I drive it, hopefully it won't bobble and stall with the fans on high. Also installed new Derale with correct sensor, noise filter, and it works perfect, also A/C kick for fans works perfect( especially when you have a non broken stud to put the wire on in the controller ).

Put back the new One and nothing. If I did not have a sensor bypass switch wired in, it would overheat. I adjusted the potentiometer as far as the voltage would go and it would not turn on. I called Derale and got someone else on the phone. He had me bypass the system and test with an ohmmeter the sensor from the old and new controller. He said according to the serial number the sensor I have in the car and the sensor in the box were wrong for the new controller. He is sending v me a new sensor and a noise filter.
      Read this again please.

      Now that summer is back, I need to get this upgrade installed on my ride. I'm running the Holley Dominator with an LS7 in a 70 Chevelle. Other than the harness for the ECM and plug for the GM module, is there anything else? I have dual Spal fans. Anyone have the connector for the module?

      E67 ecu swap

      Parsonsj, I have an ls3 376/480 running on an e67 gmpp. Can I just get a production car e67 ecu, reflash it to a stock 6,2 c6 tune and go from there? I noticed all the n/a ls3 seem to use the e38 ecu, but the gmpp shares the e67 with the ls9. Does any of that matter?

      Rather that start a new thread I'll resurrect this one. I guess it's my turn in the barrel: I cant get my fans to run in pwm.

      69 Camaro, LSA Crate Engine, 4L80 with both Connect & cruise harnesses (trans & Engine).
      Production E67 ECM from a 2009 CTSV.

      I can set control to Descrete and command Fan 1 to ON and pin J3-49 goes to ground so I know my wiring is right.
      I can jump the PWN input (J3-49) to ground (rapidly) and my fans comes on and runs so I know the controller is working and the fans are good.

      Ive tried 128hz,110hz, 100hz and 20hz with no luck, Changed the Desired vs state table to all ones, changed everything I can think of to try and still no fans. I have read thru all 6o+ pages of a similar thread (lou's change) on lateral G and just about every thread on the topic I can find. I ordered a cheap oscilloscope from amazon that will arrive this weekend so I can test it and see if Im getting a pwm signal out.

      I know from reading it's kinda split between people that have done it successfully right out of the box and those who got to the point of pulling their hair out. I'm squarely in that second group, and I would appreciate any insight that anyone can offer.


      Set Fan control = PWM Electric
      Fans = 1

      E67 Pinouts
      AC Pressure Sensor
      J3-21 (ground)
      J3-37 (5V)
      J3-57 (AC pressure signal)
      J3-49 PWM output

      PWM Fan Control Module -
      1) Fan (-)
      2) battery (-)
      3) Battery (+) fused
      4) Fan (+)
      6) PWM output from ECM (J3-49)

      Did you try adding a pull-up resistor to the pwm line?

      I would try 10k. If that doesn’t work then two 10k in parallel is 5k.
