Anyone else using MegaSquirt on a LA motor?

Oh yeah it’s a lean burn distributor...

What are you doing with the secondary variable reluctor inside? If it’s left as an open circuit or something, maybe it is inducing current into your signal feed, conviently at the end where there is limited amount of shielding and the splice. It should be removed.


If you have any other leftover wiring at the end of the VR that can’t be shielded, make sure you twist together making at least 3 twists per inch. There is inherently already enough noise going on under the cap with the spark gaps. You may get lucky and get it to run properly, tho.
