Re: The beginnings of a Megasquirt how-to guide
What are you going to do for coils/igniter?

Re: The beginnings of a Megasquirt how-to guide
hi? and I have talked about it and there is a guy on rs25 who's familiar with ms and the eg33. he seems to think keeping ignition dwell under 5ms will prevent a burnout from happening

Also, as I hear, the signal should be set to Inverted(High), correct? At less than 5ms, and around 2.3ms for dwell (or is it duration?) Worst-case scenario: EDIS6 Last edited by BRZCory; 08-10-2013 at 06:23 AM. |

Re: The beginnings of a Megasquirt how-to guide
iirc only ms3 can run sequential spark for a 6banger. the ms2 can't. unless Im remembering incorrectly.

Also, I see you're in Clarksville. Do you know an idiot by the name of Ben who's got an RX7 now (also running megasquirt). He's been through a couple scoobies (STi that rolled, Leggy, Fozzie, a few bikes ) |

Re: The beginnings of a Megasquirt how-to guide
No, you'll need an ignitor of some kind. You can put them in the case with the MS2, but you do need them. The stock EG33 coils are dumb coils, that do need igniters. I think there may be newer subies that you can use the coils from, that are smart coils, and will fit right where the stock coils go, though. Maybe STI/WRX, but I'm not sure what engines/years. But LS coils are cheap and smart, and can make as strong a spark as you'll ever possibly need.

I sure don't.

Re: The beginnings of a Megasquirt how-to guide
Using the MS2 Extra code you can control multiple coils directly for wasted spark.

The issue isn't a control signal issue, it's an energy capacity one. Try to pass the full grounding force of the coil's inductor through the megasquirt main control chip is a recipe for bad mojo. Hence the use of transistors (ignitor) especially oustide of the control box (because they flow a lot of energy, they create heat). What you *can* do, if you have control of multiple coils, is just use the stock ignitor, because that's exaclty what it was designed for: Taking a logic-level input, and using it to control a power-level transistor (or darlington pair). |

Re: The beginnings of a Megasquirt how-to guide
Take a look at the MS2 extra manual. You add the required components when you do it. Using a BIP373, it becomes possible. It looks like they changed it up a bit since I built mine. I could have swore they used 1 VB921 per ouput instead of 2 BIP373.

Re: The beginnings of a Megasquirt how-to guide
Cory purchased a used MS2 that was pre-assembled so he may not have the option to add this in.

Re: The beginnings of a Megasquirt how-to guide
Cory's right. The MS spark outputs are logic-level, not powerful enough to actually fire the coil.
You can add ignitor modules to the board, and then fire the coils from those. Dynomatt did just that with his (wasted spark).
