:roflol:

might as well wait another month, but I think there's a limit on paypal claims so look into that.

Yep I put 29 July so just sent him another.

Yes there is a 45 day limit on paypal Paid on 21 May added a few more days so I make sure I have time to file my claim.

You bring up a good point; I also paid for mine, but have yet to hear from him...  I'll check the dates and see what's going on here.  For all I know, the guy could have died or something!

Honestly, I don't know how someone can stay in business with zero contact of any sort.  There are only a few choices if you want a controller that has PWM but really it's not that crucial.

Didn't want to set it up with another if that one was coming in.  Like to do something just once if I can.  So will wait till I either get a refund or the controller.

I have the 2 speed DC controller. It took just over a month and minimal contact. This was 1 1/2 years ago.

As in none till it arrived.

I can't remember. I went through all my old emails and could not find one to DC.

He does not reply to emails at all.   I'd recommend waiting 30 days and then contest the payment.  He will have a few days to come back.

Oh, I heard that Flex-a-lite updated their variable controller, pn #31165.   It now has PWM technology.  It supports up to 45a which is low but should be fine for the low-speed circuit.

Well I'm to late for the 30 Day mark that went by last week. :brick:

Was thinking of the Flex-a-lite and still use a larger relay for safety.  Just waiting on how this turns out.

In my case, I rather use the DCC one because it is all wired up; if I run the Flex-a-lite one, I would have to rewire everything...  Brian did respond to some of my mails on how to diagnose his controller, but since I purchased the new one, I have not heard back from him!

With the Variable controller I don't think you run a relay.  It's all controlled in the black box.  You can't have PWM on the switch side of a relay.  It must be on the power side.

If you went with the adjustable thermostat then you would run a separate relay.  This is what I'm running now.  The fan is either on or off no PWM.

In my case, I rather use the DCC one because it is all wired up; if I run the Flex-a-lite one, I would have to rewire everything...
It wouldn't be that hard to rewire it as you've run all the wires already.  You would just need to cut and reconnect to the new controller.

Thought about that right after I hit enter.

did you order the 2 speed or the variable speed one?

2 speed

there are 2 relays on that one

I think i would like to make my own PWM controller - have done some research and the control portion can be done with a PIC microcontroller and an LM35 precision temp sensor. seems that you can get parts that will operate from -40C to +125C (+150C for the temp sensor) so that is a fair enough range i think for automotive use. there is a power (high amp side) portion to this which i didn't get into yet but that should be straight forward once i figure out the schematics and code. the nice thing about it is that with the microcontroller you can basically program whatever ramp-up ratio you want and also whatever temp to rpm ratio and the percentage increase can be variable as well (non-linear i mean). I would have to be re-written but they are cheap enough that i can have 3 or 4 that can be swapped out on the road. I would also want to have an ambient (outside) temp probe and have the fan speed based on that, like in the winter most likely shouldn't be running at all or low speed compared to summer when you need more airflow to get the same cooling effect. And i'm also thinking some additional inputs like oil temperature (if there is an oil cooler in front of the rad), inlet air temperature (for the forced induction so it will turn on to run air thru the intercooler at low travel speed) and some other things might come up (like A/C control if I ever get one installed which is not very likely, or manual OFF/FULL override mode)
I just need time to work on it...

will probably cost more in the end than buying one from this guy but the fact he didn't answer any of my emails makes me look somewhere else.

I don't like the spal one due to lack of features.
