EDIS on EA82T, can I remove the distributor?

I may eventually use MS to control fuel, but no immediate plans to do this yet. I was hoping for a clean EDIS install with factory injecton. Thanks.

I wonder if there is a way to use the VR sensor to trigger the fuel injection. I wish I had an O-scope to see what the signal looks like. I bet there is a way to replicate it to make the stock ECU happy by using EDIS as the trigger.

Everything GD has brought up is spot on.
I would recommend going full megasquirt as it will remove many, many headaches whenever you have to interact with the stock management. Fuel control is the reason to bother with any of it.
Also, the Edis setup has been superseded with ms1 extra and on board coil control and having done both I would recommend the latter every time.

Also, engine sometimes misses and I can see this in the pulse from my timing light. Not bad and goes away at higher rpm. I decreased gap in all my plugs to see if it would go away, but it did not. It doesn't do this on the stock ignition. Is this normal? Could it be running this way becuase timing is fixed?
Planning on purchasing a MS3, but want the edis setup to run as good as I can get it first. So will MS3 connect direct to the coil pack (bypassing the EDIS module)

It should run stable on it's own. Few ideas on stuff to watch for.
The Edis sensors and wheels can be tricky re. gap and alignment. Have a scope to check your signal? Ms would give you a look at this.
The sensor bracket can have vibration issues
Electronic noise can also be a problem, are you using the condenser for the Edis coil? They are particularly noisy. Tidy, protected wiring helps with this also. The Edis wiring has the important wire bits shielded for noise.
