Hey all, I've got a 3 pin coil from a 1997 VW 2.0. It has a 3 pin bosch connector on it. How does this differ from my standard bosch coil with a (-) and switched (+) ?
I searched but didn't find much. Thanks in advance!

This is probably the same kind of amp that I'm having problems with. I use the dwell control, but at some point the ignition starts to misfire. My dwell is set to pretty low 3.0ms, so it should not heat the amp too much... Invert is set to "no". The engine runs perfectly, but after about 30min the misfiring starts and gets worse... The signal from MS seems to be ok (according to scope), but the timing light shows missing pulses even from the wire that goes from coil to dizzy. I tried another amp, but the whole system broke down last night. Had to re-flash the MS, etc...
My next step is to empty the old amp and put a VB921 into it. That way I can use the existing coil and wiring... FYI: The Huco amp that I have features a ST BUB941ZT driver.
But PLEASE let us know if it works for you, so I can be sure that my problems are elsewhere ;). What is the partno?

Installed VB921 inside VW 3-pin module today. Seems to work fine after a short testdrive. Also as SuperCab mentioned, you can bypass the negative side and use it (ex. if you have VB:s on the MS board). I have a MS-I with v2.2 PCB and replaced R25 with 330ohm and jumpered it to the X12 output that is connected to the module.
