When I compare the green pattern to Alex's green pattern mine is symetrical and his isnt making it seem like I am missing a mark/tooth (i dunno)

Right so I got a reply from Phil regarding the logs:

I have replied and sent him the 4 logs where its rising edge, cam inverted and the other 3 ect to see what he says.

Is it possible I might have a faulty CAS?

So I just got a reply back from Phil again:

So I am gonna swap the CAS over tomorrow and fit a fresh O-ring and hope for the best really... I suppose its possible the CAS got damage when fitting the engine and It may have hit the fire wall but I doubt it.

No CAS input (no spark etc)
 

His looks nb. I think you just need to mod the board. Will post the steps later.

His is a MK1 BBR turbo just with a MS2 instead of the stock BBR ECU since it decided to die on him.

And thanks Brain, I wont mod it my self what I'll do is relay the information to Phil and get his opinion since he built it of course.

So I swapped over the CAS today and no luck at all I took another log and its exactly the same and according to Phil its close but literally a few degress off which annoying.

He asked for me to open the ECU and send him pictures as he always uses a opto circuit on MX5's however he has had a few cases where a VR circuit has been needed instead which I find odd since from what I have read VR was only introduced from MS2 onwards so my MS1 wouldn't of been using VR it would have used opto and that worked, badly but it worked hence the upgrade since I had surging issues.

Anyways I have attached the images for you guys to also take a gander at:

Need to see bottom of the blue board.

All that wiring and no flyback on the idle fet...

Okay I got a reply from Phil and basically he is asking me to remove two links and add two wires, I am not sure what this is actually going to do but he said just to try it again after that.

Just to keep you updated here is the pictures he sent me:

And remove these links.

I have to add these wires.


Does anyone actually have a idea what I am doing here?

Figuire out that basically I am adding hall sensor support for the 4g63 cas, which seems partially done all I am doing is finishing it off in a sense. any reccomendations for soldering iron and wire gauge I should use?

getting a new iron since i let someone borrow mine and well they decided to utterly fuck it...

see attachment.

and look at this post: https://www.miataturbo.net/megasquir...94/#post940609

Ahh brilliant thank you brain, so basically Phil forgot to update my board when upgrading to MS2 atleast on that side of things.

Atleast that pretty much confirms that I should be good to start the car tomorrow or atleast progress to the next stage atleast!
