Megasquirt Build

Got the stimulator done.
Back of board...



Front of board shown in the case half. I need to drill out 1 hole for the last pot i installed.



I'll probably order the ms kit after christmas. Got enough to keep me busy for now

 

pulled the plug finally.
megasquirt II 3.0 kit on its way

 

Got my megasquirt kit this past week and started the assembly. I unstickied the post but will keep posting as i go now

 

Power supply section is done. I need to get my meter and snip the extra leads off the board. The jumpers are needed for iac stepper motor control

Thats alot of wires
Ive actually got a wire harness i stripped down that should work pretty good.
I'll keep that in mind though. Labeling would be nice

 

Finally got a chance to check the power supply section of the board for proper opperation. Found a cold solder joint on pin 20. Quick fix and all is good to move onto next step

 

We have communication with the board. couldnt find a serial port cable so found a usb to db9 adapter at best buy that works.

On to the next step

 

We have communication with the board and proccessor
Tuner studio is showing battery voltage from the stim and clock is counting.
Input section next

 

One question for those of you that have gotten farther than me.
For running off the points you just need to build the coil - circuit, correct? All the jumper options should be done for using the neg coil trigger.
Don't need to change anything with the distributor/coil on the jeep, the megasquirt just taps into the neg side of the coil for the pulses. Not doing ignition control with ms, just fuel

 

Thanks. I think i started puting a few components on but havent gotten much farther this last week other than reading ahead in the directions

 

Thanks mike

 

Almost done. I didnt bother building the vr circuit. May or may not add the parts for that.
Only question i have is whats the deal with C1? Directions say at end to make sure all parts needed are soldered on. Even points out c1 as being commonly missed. I don't see anything in the directions about it other than the parts listing?
Just add it? Not a special option part?

 

Found c1



Now to build the harness for the jeep

 

Thanks tim

I saw the c1 on the board and in the end of instructions they point it out as being commonly missed, but couldnt find it in directions. Step 1 i think of the clock section
