do u have the heater hooked up?
did u turn it on while bleeding?
u need to use the hose wit a little strength to blow out bubble if u do that
it should blow them out quick...not 15 min...
get combstion tester u can find them for 50 buks and lower..
to be 4 sure..
if thats the case redo ur head gasket and shave head slightly
use indian shellac on it...
when redo gasket v8 guys use it on 1000 plus hp motors to ensure it doesnt blow...

Sounds bit crazy to rev the motor while pouring coolant,but works.

I can try it once more but I'm pretty sure I did it almost perfectly. And I did indeed use that bleeder screw. Bubbles are appearing somewhere in the system. I'm thinking there's a leak somewhere. the radiator is aluminum and is actually bowing up and the over flow coolant tank is filling completely up because of this pressure that is causing the radiator cap to open.

I have been running it for 2 years now and I use to live in Savannah and I didn't have any problems with keeping my engine cool.

what settings are you using for youe set dials?

i do exactly what the directions say and with the dials set to 0 and 4 i get 4 pulses....perfect! then disconnect the power and set dials to 0 and 2, and reconnect power, i get fans running!!! FUCK! .

I also get through the programming fine... i get my 4 pulses as well. You mean you have your udials to 4 and 4 when you get your 4 pulses... anyways, I set it to 0 & 2 as well then reconnect power but unlike you, my fans won't turn on. Wtf?

xiaphin · 11-24-2010, 05:41 PM

I cant even get them to pulse. Mine just come on constantly when power is reconnected to B+ after connecting the manual switches and setting the dials per instructions say. All my wiring is good except for maybe the AC trigger. Where did you guys tap into for this connection? I did pin 41 off ECU for AC switch. Right or wrong?

Andres_G · 11-24-2010, 05:53 PM

#41 off the ecu? Where is your controller mounted?

Anyways, mine is mounted on top of the fuse box and I just tapped into the connector that is running to the compressor for the AC trigger.

Don't be surprised if you have a bad unit, I've returned two for warranty and the third one seems to be working fine now. (Knock on wood)

xiaphin · 11-25-2010, 10:03 AM

Controller mounted in glove box along with all my other controllers, like so.

My A/C compressor isnt on the car right now so I figured #41 would work. Here is a diagram. Do you have to have this wired in to properly setup the fans? Directions arent clear on whether the car has to be running or not either. I assumed just ignition switched on which is what I tried, but if its a POS then how to figure this out?!?

Andres_G · 11-25-2010, 11:23 AM

Me think the instructions are confusing you, much like they confused me. (I had to call FRsport 3 times!)

Confusion#1. On step #4 the AC input needs a constant 12V (hooked up to the battery) not hooked up to the actual AC trigger like I thought.

Confusion #2. On step #7 it says to "disconnect the switch wires and connect all wires." What it doesn't say is to unplug the constant 12V that was on the AC input.

The actual AC trigger wire is not needed to program or under normal operation of the unit. But if you like to run your AC then go ahead and hook it up. Quick way to find out if #41 off the ecu is the right one is to check for 12v when you hit your AC button on your climate control.

FYI, But you do have to have the 12V IGN trigger hooked up when programming ( I didn't have mine hooked up and it wouldn't program)

I didn't have my car running when I programmed mine. I did not have my ign to the ON position when I programmed. Instructions don't say to have it on at all.

Oh, and nice set up you got there. Although it might be a pain if you have to reprogram the controller.
Let me know how this goes for ya.

xiaphin · 11-27-2010, 12:57 PM

Did like you said but with the ignition switch off and got it to pulse. After programming, turn ignition on once and they dont come on, like they should. Turn ign again and they come on WTF. Car isnt running yet so no reason for the fans to come on when ign is switched. Gonna check that #41 input for ac later today although it has nothing to do with the fans not functioning properly.

Andres_G · 11-27-2010, 10:26 PM

So did you get them pulsing?

Yes, my ignition was off when they were pulsing.

On mine, sometimes when I unhook the battery and reconnect it...I turn the IGN to ON and the fans come on, take out key and they stay on. The only way they turn them off is if I turn the IGN to ON and turn it back OFF. WEIRD....

xiaphin · 11-29-2010, 04:09 PM

Yes got them to pulse. Fans came on after i switched IGN on off and then on again like 5 min later. Didnt try your on off again trick. and #41 off ecu has 12v with IGN on. So its not good for the AC trigger.
