Finally, success!

I didn't move my distributor. I ended up changing the trigger offset to 77 BTDC, from 6 and changing the ignition capture to "falling edge" instead of "rising edge". I also had to change the Cranking trigger to "trigger return" from "trigger rise". This was a bit confusing since I ...

You can double check using methods outlined here.

Thanks for all the good advise. I double checked the resistance of the ignition wires and the four vary from 4.38 to 5.64 kohms, which is just below or within the 4600 to 7400 ohm spec. But the wire from the coil to the dizzy was at 2880, which was just above the 1200 to 2800 ohm spec. These are 8mm ...

I did some more troubleshooting today. Well I figured out what isn't wrong. I went ahead and installed the new plugs, gapped at .032 and the problem continues exactly the same. I also tried a new ignition coil and again, exactly the same. I can only imagine that it's the spark plug cables. The ...

So I finally got my car back together and was able to continue troubleshooting this problem. One of the things I changed while I was in there was the distributor cap and rotor. The misfire persists. I took Arnold's advice and hooked up the timing light between the coil and the distributor and I can ...

Good call, I'll let you know how that goes in a few days when I get another chance to check it.

Hi All,

I've been running Megasquirt II on my 16V VW Scirocco since April and have been making constant improvements to the tuning since. One such improvement was reducing the ignition timing from 20-ish degrees at idle to the manufacturer specified 6 degrees BTDC at idle. This improved low end ...

While waiting for my BIP373 to come in, I did a little experiment. I hooked up a spark plug, my ignition coil, and my megastim to my megasquirt, all on the bench. I could get the VB921 to flash an LED, but I confirmed with this setup, no spark. (though the coil would make a clicking sound). I think ...

Hi Lance,

I checked the primary and secondary windings on my coil:

Primary measured .8ohm; spec .6-.8ohm
Secondary measured 3170ohm; spec 6500-8500ohm

This doesn't meet the spec for the 16v coil, but it does meet the spec for the 8v coil. I'm suspecting that someone got the wrong part number a ...

Hello,

I'm running MSII, V3 using the VB921 for direct coil drive and got it to smoke after the second day of trying to start the car. It's a 16v Scirocco, I'm using the hall input from the distributor, and have done the following mods to the tach input circuit (see picture below)

Thank you for providing this information. I am considring using a similar vw throttle body on my 16v Scirocco. How much does the throttle plate open when you apply 12v to pins 1 and 2? do you think that the opening is proportional to the current applied? AKA PWM Idle control? I'd like to do some ...
