They actually make you assemble the pcb...Why?

they dont MAKE you its just cheaper.  Gurov is that before or after you filed down the board to fit?

molex  connectors use for darsondris' harness:

so it is basically plug and play now huh

3.0 pcb here:

barometer attached to the back of the 3.0 board. 2.5 bar map sensor.


parts bin:

v3.0 motherboard, this is my black-cased ms1, the stuff on the proto board is an extra optoisolator for a 2nd trigger while i was trying to get it to recognize our sensors, the two silver transistors are for driving ignition coils in  waste spark, they're ran off the very top and very bottom leds, with MSNS it works out well, they are D14 and D16


my jimstim that burnt out its own cpu, so i lost the wheel generator:


old test bench:


the signal generator



the signal produced

3.0 motherboard, this is my megasquirt 2 box with a 4 bar map sensor upgrade, this is the mapdaddy sensor upgrade, you get two sensors, 1 main, and 1 barometer, both are 4 bar, one wire hookup for the barometer to the CPU



notice the much smaller ms2 cpu on the board, surrounded by other chips, it's a straight up upgrade, pop one processor out, put another one, connect 12v to a pin:


the back, you can see the mapdaddy upgrade wire for the barometer, and the 12v hookup for the ms2:


this is what you get if you order the 12' harness, a sealed connector. which kinda sucks cause you can't add wires to it, i just used the wires from the 12' harness


assembling the harness:




just got done building the motherboard, this was a while ago:


yet again, no magic here, i think i'm done for now. if someone wants further pictures, you're going to have to be very specific about the stuff you want

good lord, so how many have you messed with/built now?

4 total so far. modified one ems-pro box.

ms2 3.0 board - 4 map with baro
ms1 3.0 board - 2.5 map with baro
ms1 2.2 board - 2.5 bar <-- runs my car right now
ms1 2.2 board - 2.5 bar  + boost control + launch + fan + alky trigger = darsondris , ran my car on this and tuned quite a bit on it. being sent out tomorrow

sweet pics... sweet wonderful pictures...

I'm unsure on launch control right now. I want to see exactly how it works in action. Basically, you flip a switch with the clutch depressed and in 1st gear, and the rpms go to 2k or so. Then when you release the clutch, the throttle modification stops? Just making sure I'm not thinking stupid.

Alky trigger was pretty simple huh? The boost trigger that came with the enginerunup kit has managed to work it's way down from 9psi to 5psi. It now comes on when I have the EBC turned off. I keep loosing the damned tiny ass alan key.

How is the control for the fans? You just set a temp on/off? Can it control both the hi/low fan settings?

-JNY

launch control:
flip an arming switch, push down clutch, floor the gas, rpm goes to 3000 rpm, keep gas pedal down, launch, don't let clutch go out all the way, 3000 rpm limit still on. keep gas pedal down, go to redline, keep gas pedal down, keep gas pedal down, press clutch in, rpm goes to flatshift rpm, keep gas pedal down, put into next gear, release clutch, keep gas pedal down, rpm goes to redline, keep gas pedal down, push clutch in, rpm goes to flatshift rpm, next gear, repeat etc.

i think i'll have a huge problem with the "keep  gas pedal down" bit

alky trigger is just "output 2" which is generic relay switch off whatever variable

fan control has builtin hysterisis control, on temp and off temp, it grounds a wire, so you just hook the stock fan relay to the MS and go.

i always kepp the gas down.. why would you life shift. that is for gynes.. lol

cause this will have a 2nd rev limiter that doesn't abuse the shit out of your clutch, gears, engine. etc.

i know but seriously if i am racing.. no lift shiftin for me

is that what keeps killing your tranniys?

pics of the auxilary output board i made:



two big transistors are the for driving PWM outputs, one labeled B is for boost control, to the left of it is the water injection valve/nitrous valve
top left is the input for map switching.

bottom row from left to right
shiftlight, shiftlight, output4 (FAN with water injection enabled), output3 (generic output with shutoff delay)



back of the prototype board, the two long busses are ground (middle), and +12v (top)


the socket has to be cut to allow for all the outputs to be brought up topside:

That doesn't have anything to do with cars.  It's a time machine.  Or maybe it is a flux capacitor soooo the car is the time machine.  lol  looks great though.
