EDIS4 missing tooth 90 degrees behind

I have my EDIS missing tooth 90 degrees behind rather than ahead of the sensor. Its a 1342 fireing order, could I switch plug wires for cylinders 1 and 2 with wires for 3 and 4, being that they are 180 degrees off, like my toothed wheel? The wheel is heat shrunk on so I'd rather not remove it , but a I can if I have to.
Thanks!

If it was me I wouldn't move the plug wires. I'd just swap the wires at the module. ie. swap the wires on pins 10 & 12 that come from the coils. It would accomplish the same thing.
On my v8 (EDIS8) I did something similar in order to simplify plug wire routing. My coils fire ACBD instead of ABCD.

Thanks for the reply. Upon closer inspection, looks like I am gonna reposition the wheel anyway as it's not exactly 90 degrees behind.
Thanks again!

That would certainly be the optimum solution IMHO.
Good luck.

I need some help if you guys can do so. I have a 4age 20v blacktop in a mr2. Ran perfect. Then megasquirt came along. I am super new to this. I put the EDIS 4 on it with COP's as it came. I can get it to start but I have to tell megasquirt to advance timing to 48degrees for it to start at all and it runs ok at that? WHAT AM I DOING WRONG? I set the trigger wheel 9 teeth behind the missing tooth as it says all over the internet to do running clockwise and this thing is making me advance my timing super far. Is it possible i have another sensor messed up? Or a calabration I missed somewhere? Please help. -Jake

Check it with a timing light - when the engine is set to 48 degrees advance, are you in fact getting 48 degrees of advance? If you are not, what is the real advance amount?

Me too, i couldn't start my engine for a week wondering why, i re-checked everything but helplessely;
then i checked with a timing light and the advance was something like 50-70 deg btdc...
So with the help of my friend i checked the timing and he was moving the vr sensor until the timing was set to 10 deg btdc and the sensor position was actually the opposite from what the edis manual says, 9 teeth ahead of the gap...
The engine cranked from the first try
