I haven't noticed any strange vans parked out in front of my house
Hope it shows up cause I won't have more ready to go out until the end of the week unfortunately as I HAVE to finish this paper mid week
(don't ya love procrastination?)
Anyway, keep me posted.
An update to all:
Been busy lately, but will be producing more this week for the end of the week for some orders I already have and then maybe a few more. After that I will be caught up and stay caught up and orders will go out in a more timely maner.
Dave,
Yea, got it yesterday and installed it in 30 minutes..had some wiring preset up to speed things. Interesting problem which may be related to my running an AEM standalone ECU in my 03 I'd like to pass along. With the engine not running-ignition ON,, the foglights work great, independent of the lowbeams/hi's as designed.
However, if I start the car, I can initially hit the foglight switch and they will work independently but if I then turn the fog switch OFF once and than ON, the system reverts back to the original setup where the fogs only come ON with the Low's. OFF w/ the Hi's. I believe if I wait several minutes with the car running and foglights off, the system will revert back to a one shot use of the independent fog's...wierd?
I checked the Power On source and it stays Hot the whole time so that's not the problem. I know the AEM ECU does so strange stuff with the fuse box output when the car is turned off but only after a wait of 5 minutes but didn't think it messed with things when the engine was running.
Know it would be hard for you to get a feel for what might be a fix without having the system in front of you but any ideas would be appreciated. Anyone else out there ordered this box for their AEM equipped EVO and has installed it yet ? Feedback?
Cheers,
Craig

Thats the downside to the design, its not your ECU. There is a capacitor in there that HAS to discharge before they can be turned back on. I timed mine and its somewhere in the 3-5 second range. If you keep pushing the button it just keeps charging the cap and makes you have to wait longer. This not really a "flaw" in the design, its known and unavoidable the way I designed these. Are there ways to eliminate it? Yes but not for as innexpensive as I am able to make these as it would involve a similar circuit + a chip and right now I don't have access to a chip programmer, maybe in a month or two I might.
Try it out see if thats the issue you run into. I tried to make it known this was the case as it could be frustrating, however I have found that its a mute point for actuall usage conditions. The only thing its going to prevent anyone from is flashing their fog lights. But I have yet to run into a time when I couldn't just flash my high beams.
It should work fine like this. Push and it comes on, push and it goes off or turn the key off and they go off. If you turn them off and want them back on you just have to wait a few seconds.
Sorry I know its not perfect, but its what works right now. Hope this helps. If not let me know!
Dave,
Understood...this is the way it works with my car when the car is not running but ignition ON...have to wait 3 seconds before the Fogs will relight due to the capacitor discharge need. However, when the motor is running, the wait period from ON-OFF-ON is several minutes which I am attributing to my AEM ECU somehow since my in cockpit Tein ED shock controller has a similar glitch. This AEM box has usurped the ground control system for all the car's electronics including, I'm sure, that front small ECU module in the fuse box that controls the headlight/foglight logic circuits.
I think your system is a great deal and works fine for me if I leave my fogs on while driving and don't go and turn them off expecting to relight them until several minutes later.
I know you're busy but if you give me an idea what values I should see at the relay pin with the system on or off, I will check and see if there is a difference causing my situation just for my own/our curiousity.
Again, I think your foglight circuit modifier is a great deal and it is my AEM electronics which have made my system act a bit differently.
Thanks,
Craig

OK I completely missunderstood your first post. This one makes much more sense but it doesn't
I see what your saying. In my head I can't see why this would cause a problem unless there is some strange feedback coming through your ground wire?
Its easy enough to test everything, but not easy to test to see if your getting funky feedback through the ground.
At the switch you should see continuity between the top two pins ONLY when the button is pressed. The top pin should only see ground when the button is pressed. The second pin down should be grounded all the time.
The Red wire is obvious and it should show 12 volts all the time and the ground should see ground all the time.
The other area you could see some feedback maybe is the relay wire. That wire shows the fog lamp relay ground when activated. That pin on the relay should ONLY see ground when the lights are on and should be completely open otherwise.
EDIT:
The more I think about it, the more it would almost have to be in the ground wire. The Yellow wire is serperated from the *circuit* via a relay and the Black wire is seperated likewise. The only wires that connect directly to the circuit from the outside are the +12v and Ground. So I would make a slightly-educated guess that the feedback in your ground system is causing the delayed discharge. You could very easily try and see if a diode would fix your problem.
All you need is a diode between the ground wire and ground. You want the Anode end connected to your ground wire and the Cathode end connected to the actual ground. This should provent any feedback by only allowing the current to flow in one direction.
Any diode from radioshack or where ever will do

For $0.59 its worth a try sometime maybe
I'll continue to think about this and make sure I am on the right track, but I am pretty sure thats your problem.
This is the only thing I can think of unless something else slipped by my high standards of QC? But you say it works fine with key on - engine off, so its gotta be some sort of feedback as long as all the wires are connected properly.
I really want to get more of these done and get ahead of myself so I have extras sitting around for new orders and incase something does happen to someones so I can send out ASAP.

Any updates Dave? I accidentally special ordered the IRNF510's and the shop i ordered them from won't take them back.. they charged me 10$ for 2 of them as well...
I'm interested in purchasing 1 of the units, i sent you a PM but no reply. No rush, just wondering when you want the cash... (before i wind up spending it heh)

Life has been hectic. I HAD to finish my thesis this last week and haven't had much time to breath. I have a break in life right now for the next week or so, so I am gonna churn some units out. I appologize to those that have paid and those that have PMed me with no response. In 2 more weeks I get my life back and I will be ahead of the game with these and a couple other ideas I have on paper.
I did do some work this weekend on them, but I did not complete them and I am sending a message to each person that has paied/emailed/pmed me and giving an update. I went ahead last week and bought a new chip programmer for something else I need to make so I decided to just bite the bullet and order some chips and do this module with software and eliminate that damn off-on delay all together!
I'll post more info about that in a couple days. I also plan to (once I have a system setup to get these out in a timely manor) stick a page on my website with a pay now link or something to make this ordering process easier.
I'll update more later. Now onto answering my unanswered PMs!
wow i got to say to boosteed i think that is great and keep it up i this is the first time i heard ,read or anything and would like to say what a stand up guy with all his life going on and this too by the way i hope the baby is good
god speed

Anyway I wanted post an UPDATE
A few went out this am but not all of them that were supposed to go out. To make life easier (or more difficult, I am un decided thus far) I decided to make my own circuit boards for these to speed up the assembly process. We my first batch of circuit boards this weekend (ever) didn't go as well as I had hoped, so I only got a few usable ones. I am going to make some more tonight and I will drill them and asemble them tomorrow. So the rest of the "backorderd" units will go out wednesday. I'll try and send out some PMs to those that have paid today to tell you which round yours is in. Thanks again for your patience. I have learned alot through this process about myself and my time and making promisses too early so I'll get these done and THEN make some more and THEN be ready to take more orders to go out the next day.... I think once I figure this out it really won't take too much of my time anymore, its all this initial planning and engineering and parts sourcing, but I think I am at the end of that.
