Automatic Ic Sprayer

[LightningGSX]

Do you guys have laptops? How about this?

I can add up to 3 more inputs for various things.You could use it for nitrous, IC spray, water injection, etc.

looks good. Are you going to make the kits also?

What do you mean by kit?

And I could pre-program the switch, if you don't have a laptop.

Shitty drawing, I haven't done a schematic capture yet.

C1= 100uF 25 volt electrolytic cap
C2= .001 uF 25 volt ceramic caps
C3= 10uF 25 volt electrolytic cap
C4= .01 uF 25 volt ceramic caps
D1 and D2= 5.1 volt zener diodes
R2= 2.2k 1/4 watt resistor
R3 and R4= 1k 1/4 watt resistors
R1 = 2k 1/4 watt metal film 1% resistor
IC1= Microchip PIC12F675
ADC3 controls the relay and may need a npn darlington transistor or a p channel MOSFET(radio shack) depending on the relay used


IC1 needs to be programmed with my code, I'll do it for like $15 w/chip included.This works in my simulator, but some of the ceramic caps may need slightly different values in the actual vehicle.Everything should be available at radio shack, except for the 12F675, I have a million of these anyway.You also need a switch and a DB-9 serial plug and possibly a max233 chip depending on your computer.Total parts should be around $25-$30.I can program the temp and tps values when I burn the chip or you can give me a little $$$ and I'll give you the above software.

damn dude, i could have really used some mad electronic skills like that in my physics 131 lab today!

that would be excellent, i'll start researching pumps and fuel pump lubrication. free source of pumps would be killer.

i bought a pump from these guys awhile ago

pumps (http://www.sprayingequipmentsupply.com/pumps/diaphragm-pump.html)

i was recommended them by a few other guys who have made their own water injection systems. if my car ever runs right i'll start putting that onto as i have all the parts just sitting around.

[LightningGSX]

Are you guys talking about water injection or IC sprayers?

[Super Bleeder!!]

i'm pretty sure they are all talking about sprayers, sans me

A cheap inline windshield washer pump will work in that case.You don't need much pressure or volume.
