? DHP installed(NO FAN after turned off) I have a 00 GAGT and I Just installed my DHP reprogrammed PCM I thought the fans were supposed to stay on ofr 2 minutes after the key is turned off) Mine aren't. Did I get burned? Is this chip really reprogrammed or did I just spen $215 on a scam??????????? If anyone can help me I will appreciate the input. Thanx ALSO: it seems to be shifting better ( Thats one good thing)

AFAIK the fans only stay on when the temp is above a certain point. (180?)

Yeah but guage said 195-200 degrees.

2 minute fan on at key-off (this feature activates when engine coolant is 179 degrees or greater

That was taken right from pfyc's website.

Did you buy from DHP or PFYC? If either of those you dint get ripped off. Take the car for a 20 minute drive and then shut it off and see if they are on. Do you notice anything else that is now different. DHP does everything it says it does for me.

Got it from PFYC . It does everything it says except the fan turn on. Could it be because of the caspers high speed fan switch i have. or the hypertech 180 thermostat. I wish I knew why my fans arent working. (replaced both relays and the radiator fan motor and the Coolant temperature sensor, and the fan only comes on when I flip the switch. No matter what the temp is at. SOMeone please Help me with this one I am clueless!

None of that would affect it since i have the same things. I still use my fan switch every day all the time. My temp NEVER gets over 200 no matter how hot it is outside.

i was just hoping that with the DHP I wouldnt need the cooling fan switch BuT I was wrong I guess i cant sell it cause i still need it or else my car will over heat

You dont NEED it but for me personally i like to keep my engine and trans as cold as possible at all times. Thats just me though.
