Compustar CM3000 Brain Problem

I just installed a 2w900fmas unit on a 2005 f150, I got it all done, installed the security bypass, tested everything as I went including remote starting it, arm and disarm, door locks, dome light supervision with a relay, everything.

 I got all done wiring and put everything under the dash, and now nothing happens when I push the tach learn button on the brain and it will not learn the remote anymore, but when I cycle the key on and off 5 times the brain clicks like it is supposed to.

I checked all the fuses and checked all the wiring, unplugged it and the replugged it in, stilling nothing, so I took the brain out and plugged it into a car with the same setup, same thing happens.

Now here is the retarted thing on my part. I took the good brain out of the car that was working fine and plugged it in to the f150, I just plugged in the main wiring harness and the tach button worked, so I proceeded to plug everything else in and when I was done plugging the other harnessed in the good brain now acts like the other one. Nothing smells burnt and all the wiring checks out. Any ideas? Also is there a way to reset these brains to factoy?

WHAT DID I DO, PLEASE TELL ME I DIDNT COOK TWO BRAINS!!!!!!!!!!!!!!!!111111

Had this happen to me once on a 1999 Chevy PU that I had to fix for antoehr installer. He had the tach learned and everything and for some reason the system would not remote start. After I fixed his wiring problem, I couldn't relearn the tach on the unit because the tach button didn't give me a resonse. I double checked his wiring for the tach and it was correct. What had happended was that the battery drained in the process of him installing the system and when I came to finish the system, I tried to relearn the system with a dead or near dead battery and it didn't give me a proper reading. I charged up the battery and replaced the CPU and it fired up properly with the wiring it had.

Another thing to look for is that you have the proper antenna for the system. Make sure it's a 2W900FM antenna and not the 2W433FM antennna

Try relearning the remote controls. This takes it out of valet and also resets the controls.

I have had this same problem  and have been looking for the solution  for  the past month and a half!  When you program the remote make sure only to go between the accesory and the on/starter, then it will get out of valet mode.  Now everything work perfectly.  Compustar is a great product with very sh*tty directions be ause they have  very poor translations into  English.  Good luck!

I just want to make sure that you are in fact toggling the ignition ( start in the OFF position ) to the ON position and finishing in the OFF position 5 times FAST ( within 3 seconds ) and finishing in the OFF position. I've told this to many member's of this forum and they all tell me " yeah I tried this and it didn't work " and then about 2 days later they tell me " .... oh , I guess I didn't toggle the ignition fast enough , it works great now, thanks "

I'm not saying that your wrong, but please just make sure that your toggling the ignition fast enough, flawlessly & ensuring that you have the remote control handy to press the lock button on the one way and button #1 on the 2 way remote .
