Megasquirt + DIS???

[1FASTKINGCAB]

I have a VG30DE-TT, and I really want to run a Megasquirt. but when I start looking at all the available parts, I get lost. I know I can wire it all up and figure it out. But can you guys help point me in the right direction?

 

I want to buy the complete 3.0 unit for $330ish from DYI but what else do I need?

 

 

Thanks,

Tom D

 

P.S. I also have all the OE sensors on the motor, I want to use all that I can and ditch the rest.

The biggest difficulty with a VG30DETT is that the trigger uses the length of a slot in the CAS to determine the number one cylinder. Megasquirt works by sensing missing teeth or by using a second trigger input. I believe there's a trigger wheel from Autronic that will convert a standard VG30DETT trigger into one with an outer ring of six holes and a single inner trigger, perfect for use with Megasquirt. Alternatively, you can use a 36-1 trigger wheel and run a Ford EDIS system or have Megasquirt trigger a wasted spark setup.

 

If you want to have Megasquirt drive the coils, you need one VB921 per coil. The Megasquirt already comes with one VB921 (it's installed in our assembled units, but not jumpered), so you will need two more for wasted spark or five more for a COP setup.
