quadnie

Hell yeah man. That ---- sounds like fun.. I don't think I'm going to run out and build one, but it would be nice to know if say someday I wanted to efficiently cool oil on a quad turbo engine (me and my v8s).

Can we have some info on the EBC?

Don't worry, I'll keep the haters at bay for you.

The electronic boost controller is quite simple. At the simplest level just a Map based switch connected to a boost soleniod. You can make a map based switch from an Op-AMP. To drive the boost soleniod you hook the output of the switch to a relay which drives the soleniod.

I just used a micro controller instead of an Op-AMP, which powers the soleniod when the MAP voltage exceeds a user settable threshold. Pretty simple ----. was working like a charm when i tested it. I Found a good source for boost soleniods. I think I can piece together a EBC for less than 100 bucks, probally less.

I am working on integrating this together with my homemade AFC and throw in ignition timing control into the mix.

But it is the oil system that I am excited about, I have posted this up on 3 boards and recieved mostly negative feedback on it.

If you are interested in some of the crap I did serach for my posts a few months ago and there should be a link to a few of my AFC pics. Hopefully it is still up.

hey toalan, is your homemade afc the trailerpark hack? here's the link:http://www.carolinahondas.com/forums...ailerpark+hack
if not, is there a link to your homemade afc?
how does your car run with your homemade afc as far as not haveing individual rpm adjustments?

works in the same principle I guess as the treiler park hack I suppose, most piggy back systems work on the same principle: trim the incoming map voltage so you do not throw out a cell and use larger injectors to compensate.

Mine was very similar to the apexi AFC, had LCD and ----, but was tunable to every 10 RPM could of made it even more finer, it was *** tunning 700 RPM points but it worked.

here is the link: http://f1.pg.photos.yahoo.com/ph/toa...&.dnm=5186.jpg

looked really nasty. but it worked.

I have decided to do away with the lcd and input buttons and make it computer tunable. that way I can easily do 3d maps for better fuel adjustment, and do a 3d ignition retard control. Plus it will look much better; just a little black box with a **** to control my EBC. I am working on the setting up the Memory space of my micro controller for the 3d tables at exactly this minute. I want to do datalogging but I only have 1024 words of memory left for logging, this will allow logging of 5 sensors @ 10 samples per second for only 20 seconds. I figure this will be enough to do a complete quarter mile,Do you guys think this is enough?

BTW just got my oil cooler yesterday, got raped for shipping and handling but it arrived. Just waiting for my pump now.

btw if anyone wants to build their own missing link, I have the schematic up on the 4th pic, you can do away with the check valves if you are using a FMU. cots me 25 cents to build; 2 resistors, a normal shitty diode, and a left over piece of PCB board. Worked great with my FMU on a turbo D16, never saw a cell even at 7 psi, my 3 check valves gave out at 6.5 psi.

sorry the link i posted was screwed, this one works:

you might need a yahoo account to see it.

I just packed my turbos with axle grease.

no yahoo account needed to see it Alan. thanks, i was wondering if you had schematics for the afc & the missing link. i don't know what the symbols in the schematics mean so if you could tell me then ok, or i'm sure there's a website i can find. i sent you a message,look next to your name on the top right corner of this page. thanks in advance. i wish i knew what you know about electronic.

would pumping oil into your turbo screw up your seals if the turbo is not spinning? I'm talking about your turbo timer idea.
