I'm setting up an MS3Pro with the following:
302 Ford
Wasted Spark DIS coil packs
36-1 Crank wheel
Explorer CMP sensor
EDIS8
The problem I am having is the MS will not control spark at all. I have limp mode spark with the EDIS only.
The spark is consistently at 10*ATDC
I am not able to move it at all using the trigger offset.
The MS shows cranking in tunerstudio when cranking.
I have double checked wiring and all appears correct.
I was trying to use the tooth logger but found that it does not work with EDIS. Correct?
My CKP- wire is not connected to anything. Is this correct?
Any advice is appreciated.
The ignition system and crank wheel worked previously with an older MS2 setup.
Thanks

Re: MS3Pro Cranking Spark EDIS
Also please confirm the wiring between the ECU and the EDIS module.

Re: MS3Pro Cranking Spark EDIS
Sorry,
I thought I attached the file the first time but it didn't show up.
I have it wired according to the manual.
PIP=CKP+
SAW= Spark A Out
CMP+ and CMP- to the cam sensor
The VR crank sensor is directly to the EDIS module.
One question is about the CKP- wire. Is this left open in this arrangement?

Re: MS3Pro Cranking Spark EDIS
Yes, you don't use CKP- here. Leave it floating.
Try changing dwell type to standard dwell.

Re: MS3Pro Cranking Spark EDIS
I tried setting to std. dwell with no change. Tried fixed timing at many different settings and stays steady at 10* ATDC.
After researching the past couple days, I think I will just spend some time and mount up the LS coils I found in my stack of stuff. Sounds like a better way to go in the long run.

Re: MS3Pro Cranking Spark EDIS
All that might do is give you a new set of problems. EDIS is working with perhaps thousands of MS, so you obviously have a fault somewhere.Npieces wrote:I tried setting to std. dwell with no change. Tried fixed timing at many different settings and stays steady at 10* ATDC.

A scope would be useful to see SAW is present.
