Does your CDI have a tacho output that you can use to trigger the Micro?
That's what I used to do on my bike when running fuel only.

Is flex fuel available on pin6 on the beta units?

I had to hardware mod the Beta unit so that Knock was available.
Do I need to do the same thing for FlexFuel, or was it available already?

For the record, this seems to be fixed by tying the bootloader wire to TPS VREF as suggested by James on the msextra forums.

Looking at the V2 schematic, it looks like I just need a 1k resistor in series, and a 0.01uF capacitor in parallel, then out to pin 5.

That sounds do-able to me?

Ok, I have the red board and it says 0.9, so I guess that's because it's one of the beta units.

Next question - is there any way I can modify this hardware so that pin5 is connected, or is it too fiddly?

It's a metal case, but my understanding is that both V1 and V2 had that same case.
Not sure what colour the board is. Will the board have the version printed?
I looked at the manual, but it doesn't seem to help.

I'm planning on using the knocksense unit if my Microsquirt can use it.

Is there an easy way to tell which version of Microsquirt I have?
I wanted to hook up a knock sensor, but I have a feeling I might have version 1 (beta) which won't have pin 5 connected.

Thanks Matt.
So I definitely should be set to "going high (inverted)" when triggering an MSD from a Microsquirt that has the VB921's built in?

Laptop has been running on battery lately, but I've had my old one on AC power (both saw this issue).

I've now put a stereo noise filter on the 12V line as well, so I'll see how that goes.
I think krisr is going to bring his scope over, so we can scope vref and 12v. I have a scope that I left at my ...

I notice in the sticky here, Bruce mentions to set the Output to "going high" when driving coils directly from the Micro.
Is this the same when driving a MSD box?

At the moment, I have it set to "going low" and the MSD is triggering. If I set it to "going high" it doesn't seem to work, so I'm a bit ...
