Alternator causing interferance to EDIS

qadir03 · Post by **qadir03** » Thu Jul 13, 2006 4:50 pm

Running EDIS on limp mode, the timing is rock solid 10btdc. However when I plug it into MS the timing starts hunting around 10-20 degs. Even when I set the fixed timing to 20btdc. I then unplugged the alternator to check for interferance and sure enough as soon as I unplugg, the timing advance is rock solid. This has been holding me back for the past week now. I have tried bringing all my ground to one source and it still has this problem. Also tried a different ignition module and vr sensor. I am going to be installing a RFI filter for the edis module next and hopefully solves the problem. I have searched the forum and I can't seam to find anyone having a similar problem. Any edis gurus have any more advice?

Thanks

Sorry for the late response, just been really busy. I am using the 029q2 code running MSExtra. Megatune 2.25. I have attached a log and my current msq. Towards the end of the log, my fusible link was loose and was causing the whole car to reset, so don't worry about that. But in the begining where the red lines are is when it is really evident. I have just installed resistor plugs and still the timing jumps around. I haven't recieved the filter yet so I am hoping that fixes it.

Just a thought, are you running shielded cable on the PIP & SAW lines to the MS from the EDIS6 ECU?

No actual experience yet, this is just something that was recommended to me

Yes I ran the wires shielded separately all the way from the module to MS.
