For a sweet set up

Ayy...Thank you sir!

That looks like a very good fan controller. I am running a stock spec 195deg stat in in my dewitts rad-fan combo/lsx 6.0. in my early Corvette. That doesn't leave a lot of room for on and off. With my current sender the fan hits and stays on 'cuz the sender shuts off at 180. What temp does the stock ecm turn on the fan for a 6.0L? And what temp off? Do I need a controller that turns the fan on @ 200 and off at 196? I really like the 2 stage "on" idea too.
Thanks, Frank

You can adjust the turn on and off temps on the computer. Usually stock is just about 205 on 196 off. Something like that.

The PCM can control them if you like, or Entropy's set up is schweet. If you just need a harness and instructions, let me know and I'll send you some info and a harness if you need one.

Thanks cj's. I would like my ecm to control my fan. Is the info and harness something you sell? I don't see it on your site ... I'm am enjoying looking through your site. You can PM me if you like or reply here...
I guess entropy didn't see my question.

Same here. I would love for my gmpp kit to control my ecu. Seems like the Entropy fan kit is the way to go. Can anyone post the instructions for the lsx entropy fan kit?

Randy, the gmpp computers can control fans just fine. I don't think they are set up PWM from the factory. The last one I did ran a pair of Derale fans. Controlled one each and you can even set it up to kick both on when it controls them separately.

You are right the ecu is not setup PWM from the factory. I guess its something that would be nice to have but not a must.

Randy,

It's really not a big deal. PWM is nice, yeah.. but fans turning on and off the good ol' standard way has been fine for me.. swap after swap after swap.

Some cars have such a large cooling system, we struggle to get them to even run at temp in the first place.. unless they're really beating on it. Autocross isn't that bad.. 60 seconds and the run is over..


Road race, time attack and road course? That could be 20 minutes to an hour. Some cars run multiple hours. That's when the BeezNeez of cooling systems might come into play.

Seems like the best way for me is to run the ecu wire to the outwore front headlight bulkhead for smooth wiring
