Im looking around on how to wire the launch control in to my 2.2. I seen that you us jp1 pin 4. how do i run this do i run pin 4 to a swtich an a ground to the other side of the switch. or do i have to run in to the board. Using a input jp1 pin 4 and a output some where in the board. please let me know thank you

 

This circuit is what you would build.

 

so do i just take the wire from jp1/4 to the switch n take the resistor an the diode to the tps 5verf

 

can you use the 5v from the proto area?
what about the zeal daught would the inputs work on that for launch control???
i've spend over 4 hours tonight readin about this

 

thanks a good question cause that will use less wire ill talk to ken or someone at diy maybe they can help us out

 

yeah i' like to figure it all out, I have the diodes and resistor, i just dont want to go and start messing with stuff and fry something

 

thank you atleast im not the only one with that fear

 

I also have been wondering the same thing

 

HaHaHa i was like "sweet someone new replied maybe they know" guess not

 

well i got it i talked to matt at diy today an we kind went over it. Pretty much just get two diodes the 1n4001 an one 2.2k resistor. run it like the diagram but run it to jp1 pin 4 an if you are using the zeal board you can jump off the 5volt or jp1pin 8 put that bad boy in an boom it worked lol. ill make a little write up to help out

 

if i can use the 5v off the zeal board i take it i can use the 5v from the proto area??? to keep it cleaner
Im using the 3.0 board
i'll just build it and see how it works

 

yeah im pretty sure as long as its a 5volt it will work just make sure u use the resistor an the diodes. cause even with mine ran to the 5volt on my zeal i push the push button an launch lights up on the bottom of megatune.

 

5v is 5v as far as the ms is concerned, especially for this circuit. The ms just needs to see the voltage drop from 5 volts to (essentially) zero.

 

Did you end up putting a little writeup together? I haven't touched my ms for a while and my brain isn't computing how to build the said circuit. Pictures would help me greatly even pics instead of writeup would be awesome.

 

i finally got around to making the launch circuit
heres a little video i made trying it out at 4k

nice work mate.

Any pics?

 

this is how i set mine uop in my proto area, its basically what the diagram shows to do

 

Thanks for that mate, so the switch is connected to ground?

 

yeah, just grounds out the circuit

i forgot to say i just used the spare pin aaron cake uses for his E fan circuit, goes to pin 25 on the db37

 

Geez, can't believe I even needed to ask those questions. My brain really is out of gear, thanks for putting up with my momentary stupidity.

would you be able to post a screen capture of your launch/flat shift settings?
