Yeah, we got 4 cyl MS users over here as well but I need to know it can handle 5 cyl.

I e-mailed a MS retailer now and waiting for a happy reply, the charged around 400 USD for an assembled MS2.

well sheeat, seeing as MS gives you the source code, download and hack yourself what you need 8-P .

Will the assembled box have the option to have a hi-voltage coil driver installed? That's going to be necessary for the EMS install...

Am I getting this right? MS is a standalone but only for fuel and timing, so what's setting it apart from a piggyback Civinco (this really doesn't apply to Swedish Mike)?

Stand-alones you can wire straight to the alternator, fuel pump, etc. Piggybacks just splice into the stock wiring and leave the stock wiring architecture intact but modify the signals to do what you want.

MS can serve as a full stand-alone, or you can integrate it only partially... When I was going to do MS in an 850, I was going to leave motronic ignition intact but replace the motronic fuel injection with a fully stand-alone MS substitute.

Eric´s answer + I can´t use a piggy back, no wires in the car, no Motronic, nothing. Read from first post and you´ll understand.

I do not know what you are referring to exacly with "high voltage", but MSII with v3.0 board has a VB921 high current coil driver installed. Whether this works with the standard Volvo coil, I do not know, as I do not know what kind of signal this coil needs.

A single coil driver will be installed, but normally not enabled. If you need it enabled we can do that without a problem (on request). You should be able to drive any standard coil with this and I haven't heard of any that don't work. Ignitors are triggered differently sometimes from car to car, but coils are pretty standard in design. And the VB921 is the ignitor in this case so we know how it's driven. Shouldn't be a problem at all!

So who's the technical writer of the bunch?

We are pretty much stand alone noobs cause the Volvo EMS are really good, we use it up to 600hp normally.

I will e-mail you in a few weeks to order, just want a few more guys to join cause it´s better when we install and tune.

Share ideas and knowledge.

Sounds good. In the meantime I'd recommend anyone interested just read through the MegaManual at www.megasquirt.info from cover to cover... maybe more than once. It starts to come together and make sense and you'll be glad you took a little time to read it all. Even if you were installing another brand of ECU there is a TON of good information in the MegaManual.

Also-- just to clarify: Are all of you running motors with the same ignition system? A 60-2 wheel at crank speed with the VR sensor, and a distributor with single coil?

Note that when this order goes through, if you buy assembled units you'll need them setup for the VR input. It's free for us to do when filling the order.

Also-- does it have an external ignitor that fires the coil or is the coil/ignitor or maybe even coil/ignitor/distributor all one piece?

Most of us got the first gen 5-cyl. Distrubutor, single coil, cam sensor, crank sensor with 60-2.

The next gen use coil on plug but also 60-2, the regular Bosch way.

With ignitor, do you mean the ignition module as we call it here, also called amplifier here.

If you mean that part it´s mounted on the coil bracket connected to the coil with short cables.

What years are the first gen/second gen? And yes that sounds like the ignitor to me and most stock ignitors work fine with the MS. (I've never had one fail to myself).

First gen from 94 to 98, the second gen came in 99 up to this day. They all use Bosch parts but more complicated on 99+ cars.

Most fast 99+ guys use stand alone cause it´s harder to tune them with the electronic TB and "hard to tune" ECU.
