My brother in law has a megasquirt from Glenn's Garage. Anyway, it has a jumper from the LED 14 to a 330 Ohm resistor then to IGBTIN. What is this for I can only find the need to use IGBTIN if you running MS2. Wondering if this is part of the on going problems we have been having.

Thanks

are you actually trying to use the IGBT for anything? Is it hooked up to anything?

I made the mods according to the FAQ. The IGBTOUT seems to be connected to jumpered to IGN. Other than that its jumpered for the VR circuit. Should I remove the IGBTOUT & IGBTIN jumpers?

 

It shouldn't really matter if nothing is actually hooked to the IGBT... meaning it's not driving a coil. You can disconnect it anyway as it's not needed, but I doubt it's causing any problems.

I guess just in case I'm going to remove it. Still have some issues with his megasquirt. Seems like its not firing the coil enough or something along those lines. Have tried stabbing the cas as shown in the guides. Hasn't ran more than 10 seconds since we had it running after adjusting the CAS sensor/tooth gap. RPM is fine just seems like the injection or the ignition is off.

 

He was probably using the led to trigger the igbt, and drive an electric fan or some such device.

 

Make sure you have the number of injectors set to 2, injection set to simultaneous, and squirts set to 2.

IF it still won't stay running after that, you probably just need to give it more fuel.
