hey, i just installed my VAFC, and ive double checked all the connections, and it is all correct. the only problem is that the unit will NOT turn on. i do hear a slight hum when i turn the key to accessory, so it must be getting power. i bought it at g-force a couple months ago and am just getting around to installing it now, along with DSM 450s, a Profec B, and a walbro pump. so, do i just have a bad unit or what? all the connections are right, the screen is just blank. this is the last thing so i can get my car running. thanks for any help.

sounds bad to me, if anything it should of turned on w/ the power and negative hooked up....don't know what to tell you....double check all the lines again, and if you know anyone w/ a VAFC, unclip yours and try the unit on there ecu...could be a broken display.

 

take it out try it at your battery. That will let u know if the unit is bad. Just a thought.

 

thanks for the replies. im trying to contact g-force now, but i cant seem to find them, if anyone has ordered from them recently, let me know how to get ahold of them.
how would i try it at my battery? would i connect BOTH powers and BOTH grounds, since there are 2 of each going to the harness? thanks
david

 

yes, just do me a favor and don't blow the damn thing...ohh and i wouldn't even bother contacting them until you find out for sure what the problem is.

 

which brings up the question if you actually spliced the brown wire in front of the black wire and with a decent distance between the two. brown one to be spliced closest to the plug.

i know it seems like a stupid question, but apexi makes a strong point about doing it that way. double check that

 

yeah, i did make sure i did that, the distance between the 2 is about an inch...thanks
david

 

another stupid question. perhaps you didnt turn to ignition ON position?

you put the key in. turn it once, you'll get accessories but the v-afc wont turn on. turn it once more, all your dash lights will light up and a/c, etc will turn on. at this point the v-afc should turn on.

just trying to cover the basics

 

yeah man, got that part too. just showing nothing on the display. what would be the best way for me to test it straight to the battery? i would hate to disconnect all the wiring...but if that is whats gotta be done...........thanks for the help.
david

 

Connecting it straight to the battery? Wouldn't the high amps from the battery fry the circuits?

 

high possibility. i wouldnt risk it. gather up your receipts and call the place you bought it from.

 

thanks a lot for the help guys, i guess ill be taking this thing back. maybe just be time for hondata anyways..........

 

alright one more thing....i tried it again last nite in the dark, and the buttons DO light up, but the display doesnt. so im guessing that definitely means the display is bad and this is a bad unit right? please let me know if this sounds right to you...thanks
david

 

Display is bad..

 

Hi-amps from the batt should NOT fry the unit... Back to basic electrical properties here.... AMPS are basically synomous with the amount of electrical flow it is capable of...

Think of your house... Some houses have 60 AMP service... others have 200 AMP service... meaning as a whole.. the house can suck up to the max number of AMPs... but does this make a difference to any of your appliances? Nope.

The number of AMPs something sux is controled by it's resistance to electrical flow. Granted if the unit is screwed and has little resistance it could fry. Car batteries can put out enough electrical flow to weld steel.

Just a thought...
