Anyone With Powerfc And Hand Controller?

[benl1981]

Hi there,

Can someone with this setup please have a look at their hand controller when they shut down the car.

Does it continue to show the display/stay powered up for about 1 sec after key is turned off or does it immediately power down?

I have a stock r33 but trying to figure out why powerfc won't hold data. I have a mongoose alarm but otherwise stock. Some say it may be to do with th eccs relay

I would have to check when the screen turns off, but the ECU must turn itself off using the ECCS relay otherwise it won't save settings first. In the race car, if I turn off the car using the kill switch instead of the key it never saves data for that reason.

But if you are using the standard wiring that should not be the issue

thanks mate. Yes standard wiring. It does have an alarm immobiliser but would think that should be on the ignition and not on eccs. Plus that shouldn't immobilise straight away after shut off.

can you usually hear a delayed click from the eccs relay 1 sec after shutting the car off? I can hear a click but doesn't appear to be delayed from when the engine stops.

yes you will be able to hear the relay click, it is over on the passenger A pillar near the door sill.

while it's not normal, it is possible that the alarm kills power to the computer. But even so the alarm would not immobilise immediately that you turn off the car, so it won't be that.

I just checked on the stagea, the PFC hand controller turns off when the eccs relay does, about 1 sec after turning off the ignition. BTW the eccs relay un-earths the computer, it doesn't cut the power.

thanks duncan. There is a blue relay next to the ecu. I thought that was the eccs location in r33 rb25? not quite sure why mine is cutting out before the 1 sec as it all seems stock. There is a turbo timer also but wouldn't think that would do it. Cheers
