No spark MS2 V3 board 1967 Beetle

[bug_n_67]

I am finally trying to start my car and I don't seem to have any spark. I have had my Megasquirt hooked up to my Stim and everything seemed to be working fine but in the car no spark. The whole megasquirt is pretty new to me so if anyone has any thoughts as to settings I might be missing that would be great. A run down of what I'm running. 1915 turbo engine, EFI throttle bodies from CB Performance, EDIS with ford module, 42lbs injectors. I have 40lbs for fuel pressure.
Also with the key just in the on position the fuel pump comes on and stays on is that correct or should it just prime for a sec and then go off till the car starts?

Thanks
John

When cranking, does megatune/tunerstudio show an rpm signal?
What are you using for rpm input?

Do you have the MS controlling a ground for a fuel pump relay? That is all it is designed to control.

Many other questions, but we'll start with the basics. And and licensed version of TS is highly recommended for tuning.

The EDIS Module is self contained and will run the engine without the MS unit.
You might want to check your PiP and SAW wires to make sure they are correctly wired.
Also check your VR wires to make sure they are connected to the EDIS module correctly.

It's usually something simple like a wire connected backwards........BTDT.

I've been EDIS free for two years now.....

But it worked flawlessly for me for two years also. It is a robust system.

So to start, I undid my MS2 and turned the engine over with just the EDIS module hooked up and still no spark. I checked it has power to it and it is grounded. So thoughts on what to check on the module?

I've never dealt with EDIS, always used direct control single coil setups. I will be helping with a wasted spark direct control on a VR this summer. You have MS2, you should be able to do any config you want w/o some other controllers being involved. That just makes for more complication and more things to fail.

EDIS is a very solid system and has a limp home mode.
If it doesn't work it will more than likely be a wiring issue.
Make sure the VR sensor is connected to the Module correctly.
Make sure the module is wired correctly and the grounds are connected.

Last, make sure you have the PIP and SAW wires connected to the ECU correctly.

Here is an old pic of my module connection.

The MS Extra Site should have a diagram of how the wires go. It's been over 2 yrs. since I messed with EDIS and can't remember details.
I know Mario at thedubshop.net used to have the diagram posted on his website that you could download.

Do you have the VR sensor and trigger wheel installed correctly????

Once you have it wired right the engine should start without the ECU hooked to the module.
If you leave the SAW wire disconnected you can then check that you have the timing correct. It should be at 10 degrees BTDC at idle to full throttle.
That is the limp home mode.

If the timing is not at 10 Degrees BTDC then you do NOT have the Sensor/Trigger wheel set up correctly.

It should run on the 10deg limp all by itself if its correct .

I haven't had a chance yet to test the EDIS module, but I'm running the MS2 extra V3 board. Also the toothed wheel and VR sensor is from CB Performance (http://www.cbperformance.com/ProductDetails.asp?ProductCode=2093) coil and module from a Ford. I will try over the next couple day to check that I'm getting 12 volts coming out of the module to see if that is working right.
