NA 94 MS3(3.57)+MS3x no start - help please
Hi dearest MS gurus,
I have a friend with a 94 MX-5 here in Germany, who can't get his newly set up MS3+MS3X running. The MS3 is a 3.57 board CKP goes through the Mainboard pin 24 and the CAM through the MS3X.
he has both signals - but he get's sync losses instantly - so the car doesn't start:
Here is a screenshot of the Composite log:
Any advice is appreciated...!

Just one more information - the sync lost reason is 38/39 = 4G63 - which doesn't help me...
(I will post the MSQ as soon as I get it from my colleague)
Could it be that his CAS is turned too much and the wrong timing affects the trigger? He couldn't get a got timing light reading - so he wasn't able the check the trigger angle

@Matt - what should be set on a 3.57 board specificly (is there something that specifies the egde of the trigger?)
Just had another look at the MS3 documentation, the V3.57 board for the Miata CAS has to be set for VR circuit with a 1K pullup, correct? I have pictures of Philips board here, and there is no pullup on R57... This should be it then...?! And the J1 jumper sits on 5-6 not 3-4, as the docu states... Damn....
I think we are a big step further now...

Megasquirt-3 MS3 Ignition - 4G63 (Miata)
The ignition input capture is the setting for trigger edge. Below are good baseline settings.
