I'm only getting spark on two. The MS is only driving one coil. I can swap the plugs at the coil and it flip flops which coil gets power.

 

okay.

and you're wired to 4N and 4R?

 

Yes, I quintuple checked lol

 

I believe this wiring to be correct for IG1 & 2. Am I wrong?

 

Any ideas or tests I can perform to figure out what the problem is?

 

you're using a basemap for the diypnp and your project is setup for diypnp microsquirt, not megasquirt v3.0/v3.57?

 

I'll check again but yes, I believe the properties are setup correctly.

Using the basemap right from that page.

 

Ok so I obviously I didn't assemble my board and I cannot find any assembly guide for my board. But after looking at images I cant figure out for the life of me what this is. and why I don't have any resistors going down the ignition portion of the board.

 

it's a capacitor working as a noise filter.

because you dont need resistors.

 

Ah ok.

TS is properly set to DIYPNP.

 

Grr no luck this evening. Tried to re-solder the IG1 & 2 wires and even tried a new location on the board.

Would converting to COP bypass this issue?

 

no.

you need to figure out why it's not firing one of the two channels. Could be a bad solder joint between the ECU and IGN1 or IGN2?

 

I honestly don't know where to start when checking bad solder joints. I tried re-locating IG1 & 2 on the board, no difference was made.

 

How do I go about testing for a bad ignition transistor?

 

the spark output comes directly from the CPU IIRC.

review the schematics.

ok got it. Do i need a stim to test the functionality of IG2?

 

that would be most helpful. but i'd make sure that your inputs make it all the way back to the CPU first.

 

Yes, I want to do that but I cant find any material on how to perform that test.
Any information would be greatly appreciated.

 

Does anyone offer a repair service?

 

Wouldn't you just check for continuity on the circuit with a meter? Sorry if I'm over simplifying it.
