I have a megasquirt v 3.57 on a 1951 International SD220 engine using a Pertronix module to trigger the ignition. In the Project properties it claims MSII Rev 2.89000. In the direct coil ignition control documentation is says to set the "Spark Output to 'going high (inverted)' up to 2.886 code ...

I have removed my dist. to lock down the mechanical advance. After I put the dist back into the engine I am trying to set the base timing. The DYIAutotune web site explains how to do this by setting "fixed timing" in software and adjusting the dist. accordingly to match the fixed value. I am looking ...

I cleaned up the area where I soldered in the BIP373 with alcohol and a tooth brush. I reassembled the MS and installed it back into the truck. I purchased a new ignition coil for an early model chev 350, one that requires a ballast resistor. The truck started and idles... at about 1500 RPM. I think ...

the BIP is installed into the V 3.57 board as per instructions. I moved jumper from center lead to of where the BIP373 should have been and soldered it into IGBTIN. Then I soldered the BIP373 into the three holes and attached with a Mica strip. I verified it is insulated electrically from the heat ...

I verified the input signal by observation of RPM on the tuner studio, therefore input is O.K. On the out put to the coil ... I removed the coil from the circuit and put a 10K resistor in its place ( between pin 36 and 12V supply) . I connected an oscilloscope across the resistor and measure 12 ...

I am having trouble getting a spark. I am running the ignition coil through a BIP373 ( directly to the coil) and the input is coming from a pertronix points replacement. The voltage drop across the pull up resistor is 7 volts and when the points ( pertronix ) are open, and when the points are closed ...

I have read the manual, and in the manual I believe I read that there is a way of making it so that the ignition coil does not stay with current running through it while the engine is stopped. My ignition coil is getting hot while I am checking the MS tuning parameters. I tried to find where I read ...

Thats what I thought....rats. I also understand that is where the VB921 is to be mounted. Hense, I do not have a direct ignition coil driver....
I guess I will have to do some more reading to figure out how to control the ignition. Either install the VB921 / BIP373 or some external driver.

Is this the pic you require?

Being new to this, I do not know how to attach a pic.

I purchased a megasquirt-2 MS2357-c PCBv3.57, firmware v2.890 DIY AT rev A from a private seller on Ebay. How can I tell if I have the BIP373 or the VB921 high current coil driver installed. I am looking at driving one coil straight from the MS box.
